Abstract
Description
本発明は、海洋構造物上のメタノール送液用配管を支持するメタノール送液用配管支持部材に関する。 The present invention relates to a methanol liquid supply pipe support member that supports a methanol liquid supply pipe on a marine structure.
硫化水素ガス製造の原料となる水素は、メタノールを熱分解させることで発生させている。ここで用いられるメタノールについては海上輸送にて受け入れる事が一般的であり、運搬船から配管を用いて受入れを行う。 Hydrogen, which is a raw material for producing hydrogen sulfide gas, is generated by thermally decomposing methanol. Methanol used here is generally accepted by sea, and it is accepted from the carrier using piping.
運搬船からの受け入れに用いる配管（メタノール受入配管）は海洋上に設置された構脚橋上に配置されているが、メタノール受入配管は温度差による配管の伸縮や船からのメタノールの圧送による配管の動きによって、配管を支持している構造部材と配管下部とが擦れて磨耗する為、最終的には配管の穴あきが発生する。 The pipes (methanol receiving pipes) used for receiving from the carrier are located on the piers installed on the ocean, but the methanol receiving pipes are expanded or contracted due to the temperature difference and the movement of the pipes due to the pumping of methanol from the ship Since the structural member supporting the pipe and the lower portion of the pipe are rubbed against each other and worn away, a hole is eventually formed in the pipe.
配管の穴あきによる液漏れの防止に関して、例えば特許文献１には、輸送用鋼管や鋼製容器の外面に下地処理を行う下地処理工程と、下地処理された輸送用鋼管や鋼製容器の外面を樹脂含浸繊維で被覆し所定厚さの繊維強化樹脂層を形成する繊維強化樹脂層形成工程とを備えていることを特徴とする配管や鋼製容器の防食施工方法が記載されている。 Regarding prevention of liquid leakage due to perforation of piping, for example, in Patent Document 1, an undercoating step of performing an undercoating treatment on the outer surface of a transportation steel pipe or a steel container and an outer surface of the transportation steel pipe or steel container subjected to the undercoating treatment And a fiber-reinforced resin layer forming step of forming a fiber-reinforced resin layer having a predetermined thickness by coating the resin-impregnated fiber with the resin-impregnated fiber.
しかしながら、メタノール送液用配管は、数ｋｍにも及ぶ長さになるため、配管の全てに対して防食施工処理を施すことは困難である。また、メタノールは可燃性液体であるため、火花が生じるような配管の切断や火気を用いた溶接補修は内部のメタノール又は残留メタノールガスに引火する可能性があり危険である。 However, since the length of the pipe for feeding methanol is as long as several km, it is difficult to perform anticorrosion treatment on all the pipes. Further, since methanol is a flammable liquid, there is a possibility that internal methanol or residual methanol gas may be ignited by cutting pipes or welding repair using fire, which causes sparks.
また、ＦＲＰ等を穴あき箇所をカバーするように施工することも考えられるが、受入時の送液圧力で破損する可能性やメタノール耐性のあるＦＲＰを用いなければならないため採用は難しい。 Further, it may be possible to construct the FRP or the like so as to cover the perforated portion, but it is difficult to adopt because there is a possibility that the FRP may be damaged by the liquid sending pressure at the time of receiving and methanol must be used.
本発明は、このような実情に鑑みて提案されたものであり、簡易な構成で配管の摩耗による損傷（穴あきや割れなど、メタノール漏洩を生じるものを指す。以下同じ）を防止することのできるメタノール送液用配管支持部材を提供することを目的とする。 The present invention has been proposed in view of the above circumstances, and is capable of preventing damage due to wear of a pipe (such as a hole or crack that causes methanol leakage; the same applies hereinafter) with a simple structure. An object of the present invention is to provide a pipe supporting member for methanol delivery that can be performed.
本発明者らは、鋭意検討した結果、配管を支持する鋼材（構脚橋の鋼材）と配管との間にさらに支持部材を設けることで配管が直接摩耗により損傷するのを防止できることを見出し、本発明の完成に至ったものである。 As a result of intensive studies, the present inventors have found that it is possible to prevent the pipe from being damaged by direct wear by further providing a supporting member between the steel material (steel material of the pier bridge) that supports the pipe and the pipe. The invention was completed.
すなわち、本発明の一態様は、一端がメタノールを分解して水素を発生する設備に設置された海洋構造物上のメタノール送液用配管を支持するメタノール送液用配管支持部材であって、メタノール送液用配管の円周面の一部に沿うように湾曲した補強プレートと、荷重を分散する底面部と、底面部に対して補強プレートを一定高さに保持する保持部とを備える。 That is, one aspect of the present invention is a methanol liquid feeding pipe support member for supporting a methanol liquid feeding pipe on an offshore structure installed at a facility for decomposing methanol at one end to generate hydrogen. A reinforcing plate that is curved so as to follow a part of the circumferential surface of the liquid supply pipe, a bottom portion that distributes the load, and a holding portion that holds the reinforcing plate at a constant height with respect to the bottom portion.
本発明の一態様によれば、配管を支持する鋼材（構脚橋の鋼材）と配管との間にさらに支持部材を設けることで配管が直接摩耗により損傷することを防止できる。 According to one aspect of the present invention, it is possible to prevent the pipe from being damaged due to direct wear by further providing the supporting member between the steel material (steel material of the structural bridge) that supports the pipe and the pipe.
このとき、本発明の一態様では、補強プレートには空気抜き穴が設けられていてもよい。 At this time, in one aspect of the present invention, the reinforcing plate may be provided with an air vent hole.
補強プレートに空気抜き穴を設けることにより、配管と補強プレート溶接時の溶接品質不良を防止することができる。 By providing the air vent hole in the reinforcing plate, it is possible to prevent poor welding quality when welding the pipe and the reinforcing plate.
また、本発明の一態様では、メタノール送液用配管支持部材は、長手方向の長さが０．３ｍ以上１．０ｍ以下であるとすることができる。 In addition, in one aspect of the present invention, the length of the methanol liquid supply pipe supporting member in the longitudinal direction may be 0.3 m or more and 1.0 m or less.
長手方向の長さを上記長さとすることで、メタノール送液用配管支持部材が配管を支持する鋼材（横桁など）から脱落するのを防止することができる。 By setting the length in the longitudinal direction to the above length, it is possible to prevent the methanol liquid sending pipe support member from falling off from the steel material (horizontal girder or the like) that supports the pipe.
また、本発明の一態様では、底面部には摺動材が備えられていてもよい。 Further, in one aspect of the present invention, the bottom surface portion may be provided with a sliding member.
底面部に摺動材を備えることで、底面部と配管を支持する鋼材との間の摩耗を低減することができる。 By providing the bottom surface with the sliding material, it is possible to reduce wear between the bottom surface and the steel material that supports the pipe.
また、本発明の一態様では、補強プレートは、メタノール送液用配管の円周の４分の１以上２分の１以下を覆うように湾曲していてもよい。 Moreover, in one aspect of the present invention, the reinforcing plate may be curved so as to cover not less than ¼ and not more than ½ of the circumference of the methanol liquid supply pipe.
配管の上記範囲を覆うように補強プレートを湾曲させることにより、配管と補強プレートとを強固に接合することができる。 By bending the reinforcing plate so as to cover the above range of the pipe, the pipe and the reinforcing plate can be firmly joined.
本発明によれば、簡易な構成で配管の摩耗による損傷を防止することのできるメタノール送液用配管支持部材を提供することができる。したがって、海洋構造物上の配管摩耗が抑えられ、メタノールの海洋漏洩リスクを抑えることができる。 Advantageous Effects of Invention According to the present invention, it is possible to provide a methanol liquid feeding pipe support member capable of preventing damage due to abrasion of the pipe with a simple structure. Therefore, the abrasion of the pipe on the offshore structure is suppressed, and the risk of leakage of methanol to the sea can be suppressed.
本発明を適用した具体的な実施の形態について、図面を参照しながら詳細に説明する。なお、本発明は、以下の実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々の変更を加えることが可能である。 Specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. The present invention is not limited to the following embodiments, and various modifications can be made without departing from the gist of the present invention.
上述したように硫化水素ガスは、硫化水素ガス製造プラント等により製造されるが、この時使用する水素ガスの原料としてメタノールが用いられる。メタノールは、引火性のある常温で液体の化合物である。硫化水素ガス製造プラントで用いるメタノールは、船舶等により海上輸送された後、海洋上に設置された構脚橋上の配管を通して受け入れを行う。 As described above, hydrogen sulfide gas is produced by a hydrogen sulfide gas production plant or the like, and methanol is used as a raw material of the hydrogen gas used at this time. Methanol is a flammable liquid compound at room temperature. Methanol used in the hydrogen sulfide gas production plant is transported by sea, etc., and then received through piping on a pier installed on the ocean.
メタノール送液用配管は、温度差による配管の伸縮やメタノールの圧送によって送液方向の前後にずれるように移動する状況にあるが、海洋上の構脚橋の鋼材上に本発明の一実施形態に係るメタノール送液用配管支持部材を介して載置することで、このような状況において、簡易な構成で配管の摩耗による損傷を防止することができる。 The methanol liquid delivery pipe is in a situation where it is displaced back and forth in the liquid delivery direction due to expansion and contraction of the pipe due to temperature difference and pressure feed of methanol, but in one embodiment of the present invention on the steel material of the construction bridge on the ocean By placing the pipe via the methanol liquid-feeding pipe supporting member, it is possible to prevent damage to the pipe due to abrasion with a simple structure in such a situation.
図１は、本発明の一実施形態に係るメタノール送液用配管支持部材の配管接合時の正面断面図であり、図２は、本発明の一実施形態に係るメタノール送液用配管支持部材の配管接合時の側面図である。本発明の一態様は、一端がメタノールを分解して水素を発生する設備に設置された海洋構造物上のメタノール送液用配管を支持するメタノール送液用配管支持部材１０であって、メタノール送液用配管１１の円周面の一部に沿うように湾曲した補強プレート１２と、荷重を分散する底面部１３と、底面部１３に対して補強プレート１２を一定高さに保持する保持部１４とを備える。 FIG. 1 is a front cross-sectional view of a pipe support member for methanol liquid feed according to an embodiment of the present invention at the time of pipe joining, and FIG. 2 is a pipe support member for methanol liquid feed according to an embodiment of the present invention. It is a side view at the time of pipe joining. One embodiment of the present invention is a methanol liquid feeding pipe support member 10 for supporting a methanol liquid feeding pipe on an offshore structure installed at a facility for decomposing methanol to generate hydrogen. Reinforcing plate 12 curved along a part of the circumferential surface of liquid pipe 11, bottom portion 13 for distributing load, and holding portion 14 for holding reinforcing plate 12 at a constant height with respect to bottom portion 13. With.
このように、構脚橋の鋼材１５とメタノール送液用配管１１との間にさらにメタノール送液用配管支持部材１０を設け、メタノール送液用配管１１とメタノール送液用配管支持部材１０とを接合することにより、配管伸縮時等には、メタノール送液用配管支持部材１０がメタノール送液用配管１１とともに移動するため、メタノール送液用配管支持部材１０と構脚橋の鋼材１５との間でのみ摩耗が生じる。これにより、メタノール送液用配管１１が直接摩耗するのを防止することができる。なお、ここで構脚橋の鋼材１５とは、構脚橋の一部（好ましくは上部や最上部）をなすものであり、Ｈ鋼などのチャンネル鋼を接合又は組み合わせることにより、構脚橋の強度を向上する形状であってもよい。 In this way, the methanol liquid feeding pipe support member 10 is further provided between the steel material 15 of the pier and the methanol liquid feeding pipe 11 to join the methanol liquid feeding pipe 11 and the methanol liquid feeding pipe support member 10. By doing so, when the pipe is expanded or contracted, the methanol liquid feeding pipe supporting member 10 moves together with the methanol liquid feeding pipe 11, so that only between the methanol liquid feeding pipe supporting member 10 and the steel material 15 of the pier. Wear occurs. Thereby, it is possible to prevent the methanol liquid sending pipe 11 from being directly worn. Here, the steel material 15 of the pier bridge is a part (preferably the upper part or the uppermost part) of the pier bridge, and the strength of the pier bridge is improved by joining or combining channel steels such as H steel. It may have a shape.
補強プレート１２は、メタノール送液用配管１１の円周面の一部に沿うように湾曲した部材であり、メタノール送液用配管１１と溶接等により接合される。メタノール送液用配管１１と補強プレート１２溶接時の溶接品質不良を防ぐため、補強プレート１２には空気抜き穴１６が設けられていることが好ましい。補強プレート１２の材質は特に限定されないが、例えば、鉄鋼材やステンレス鋼材などとし、メタノール送液用配管１１と同じ材質とすることが好ましい。 The reinforcing plate 12 is a member that is curved so as to extend along a part of the circumferential surface of the methanol liquid sending pipe 11, and is joined to the methanol liquid sending pipe 11 by welding or the like. It is preferable that the reinforcing plate 12 is provided with an air vent hole 16 in order to prevent poor welding quality during welding of the methanol liquid sending pipe 11 and the reinforcing plate 12. Although the material of the reinforcing plate 12 is not particularly limited, it is preferable to use, for example, a steel material, a stainless steel material, or the like, and the same material as the methanol liquid sending pipe 11.
底面部１３は、メタノール送液用配管支持部材１０にかかる荷重を構脚橋へ分散する。メタノール送液用配管支持部材１０をメタノール送液用配管１１と接合することにより、底面部１３が構脚橋の鋼材１５との間で摩耗することになるため、底面部１３は耐摩耗性に優れた部材で構成することが好ましい。 The bottom surface portion 13 disperses the load applied to the methanol liquid supply pipe supporting member 10 to the pier bridge. By joining the methanol liquid feeding pipe supporting member 10 to the methanol liquid feeding pipe 11, the bottom face portion 13 will be worn between the steel material 15 of the pier and the bottom face portion 13 has excellent wear resistance. It is preferable that it is configured with a member.
保持部１４は、底面部１３に対して補強プレート１２を一定高さに保持する。保持部１４の材質は特に限定はなく、補強プレート１２や底面部１３と同一の部材で良い。保持部１４は、図１や図２に示すように、メタノール送液用配管支持部材１０の側壁を構成するものでもよく、あるいは複数の支柱状の形状となっていてもよい。 The holding portion 14 holds the reinforcing plate 12 at a constant height with respect to the bottom surface portion 13. The material of the holding portion 14 is not particularly limited and may be the same member as the reinforcing plate 12 and the bottom surface portion 13. As shown in FIG. 1 and FIG. 2, the holding portion 14 may constitute a side wall of the methanol liquid sending pipe supporting member 10, or may have a plurality of columnar shapes.
メタノール送液用配管支持部材１０は、長手方向の長さＬが０．３ｍ以上１．０ｍ以下であることが好ましい。上述したように、メタノール送液用配管１１は、温度差による配管の伸縮やメタノールの圧送によって送液方向の前後にずれるように移動するため、メタノール送液用配管支持部材１０は、前後の移動によって構脚橋の鋼材１５から脱落しない程度の長さが必要である。長手方向の長さＬが０．３ｍ未満の場合は、メタノール送液用配管支持部材１０が構脚橋の鋼材１５から脱落するおそれがあり、長さＬが１．０ｍを超える場合には、メタノール送液用配管支持部材１０が長くなりすぎて、製造や運搬の際にコストが増加して無駄である。なお、メタノール送液用配管支持部材１０は、送液方向を前後とした場合の左右方向に動くことはほとんどないが、図１に示すように構脚橋の鋼材１５にメタノール送液用配管支持部材１０が左右方向に動かないようにするためのガイド１７を設置しておくことが好ましい。 It is preferable that the length L in the longitudinal direction of the methanol liquid sending pipe support member 10 be 0.3 m or more and 1.0 m or less. As described above, since the methanol liquid sending pipe 11 moves so as to shift in the front-back direction in the liquid sending direction due to the expansion and contraction of the pipe due to the temperature difference and the pressure feed of methanol, the methanol liquid sending pipe support member 10 moves back and forth. Therefore, it is necessary to have a length that does not fall off the steel material 15 of the pier. When the length L in the longitudinal direction is less than 0.3 m, there is a possibility that the methanol liquid feeding pipe support member 10 may fall off the steel material 15 of the pier, and when the length L exceeds 1.0 m, the methanol The liquid supply pipe support member 10 becomes too long, which increases the cost during manufacturing and transportation and is wasteful. It should be noted that although the methanol liquid supply pipe support member 10 hardly moves in the left-right direction when the liquid supply direction is set to the front and rear, the methanol liquid supply pipe support member is attached to the steel material 15 of the pier as shown in FIG. It is preferable to install a guide 17 for preventing the 10 from moving left and right.
また、底面部１３には犠牲材または摺動材が備えられていてもよい。底面部１３は、構脚橋の鋼材１５との間で摩耗する部分であるため、例えば底面部１３の構脚橋の鋼材１５側にゴム板などが接着されていてもよい。 Further, the bottom surface portion 13 may be provided with a sacrificial material or a sliding material. Since the bottom surface portion 13 is a portion that wears with the steel material 15 of the pier bridge, for example, a rubber plate or the like may be bonded to the steel material 15 side of the pier bridge of the bottom surface portion 13.
また、補強プレート１２は、メタノール送液用配管１１の円周の４分の１以上２分の１以下を覆うように湾曲させることが好ましい。すなわち、図１において、９０°≦θ≦１８０°とすることが好ましい。補強プレート１２が覆う部分が円周の４分の１未満の場合は、メタノール送液用配管１１と補強プレート１２の接触面積が少なくなるため、配管の荷重が補強プレート１２に十分に分散されない恐れがある。また、補強プレート１２が覆う部分が円周の２分の１を超える場合には、補強プレート１２がメタノール送液用配管１１の上半分の一部まで覆うことになるため、取り付けや溶接等の接合が困難となる。 Further, it is preferable that the reinforcing plate 12 is curved so as to cover not less than ¼ and not more than ½ of the circumference of the pipe 11 for feeding methanol. That is, in FIG. 1, it is preferable that 90°≦θ≦180°. If the portion covered by the reinforcing plate 12 is less than a quarter of the circumference, the contact area between the methanol liquid sending pipe 11 and the reinforcing plate 12 will be small, so the load of the pipe may not be sufficiently dispersed on the reinforcing plate 12. There is. In addition, when the portion covered by the reinforcing plate 12 exceeds one-half of the circumference, the reinforcing plate 12 covers a part of the upper half of the methanol liquid sending pipe 11, so that mounting or welding is not required. Joining becomes difficult.
本発明の一実施形態では、補強プレート１２とメタノール送液用配管１１を溶接する態様としたが、本発明の他の実施形態では、この溶接個所を溶接せず自由に動かせる態様、この溶接個所のかわりに底面部１３と構脚橋の鋼材１５を溶接する態様、この溶接個所に加えて底面部１３と構脚橋の鋼材１５を溶接する態様であってもよい。 In one embodiment of the present invention, the reinforcing plate 12 and the methanol liquid sending pipe 11 are welded, but in another embodiment of the present invention, this welding point can be freely moved without welding, and this welding point Alternatively, the bottom portion 13 and the steel material 15 of the pier bridge may be welded, or the bottom portion 13 and the steel material 15 of the pier bridge may be welded in addition to this welding point.
以下に示す実施例及び比較例によって本発明を更に詳細に説明するが、本発明は、これらの実施例及び比較例によって何ら限定されるものではない。 The present invention will be described in more detail with reference to the following examples and comparative examples, but the present invention is not limited to these examples and comparative examples.
（比較例）
比較例では、図３に示すように、従来通りの方法で配管１１１（材質SS400、直径20ｃｍ）と構脚橋の鋼材１１５の間にゴム板１１３を敷設してメタノールの送液を行った。定期点検の際に配管１１１と構脚橋の鋼材１１５との接触箇所のあたりで配管の損傷が発見された。当該配管の損傷は、配管１１１と構脚橋の鋼材１１５との間の摩耗による損傷に加え、海水によって損傷部分にさびが生じ腐食されたことによるものと考えられる。
(Comparative example)
In the comparative example, as shown in FIG. 3, a rubber plate 113 was laid between the pipe 111 (material SS400, diameter 20 cm) and the steel material 115 of the pier to send methanol by a conventional method. During the periodic inspection, damage to the pipe was found around the contact point between the pipe 111 and the steel material 115 of the pier. It is considered that the damage to the piping is due to the damage caused by the abrasion between the piping 111 and the steel material 115 of the pier, and the corrosion caused by the rust in the damaged portion due to the seawater.
（実施例）
メタノール送液操業において、本発明の一実施形態に係るメタノール送液用配管支持部材を適用した。すなわち、図４に示すように、メタノール溶液用配管１１と構脚橋の鋼材１５との間にメタノール送液用配管支持部材１０（材質SS400、鋼材から配管までの高さ20ｃｍ）を設置した。なお、メタノール送液用配管支持部材１０の補強プレート１２とメタノール送液用配管１１とが溶接されている。
(Example)
In the methanol liquid feeding operation, the methanol liquid feeding pipe supporting member according to one embodiment of the present invention is applied. That is, as shown in FIG. 4, a methanol solution feeding pipe support member 10 (material SS400, height from steel to pipe 20 cm) was installed between the methanol solution pipe 11 and the steel material 15 of the pier. The reinforcing plate 12 of the methanol liquid supply pipe supporting member 10 and the methanol liquid supply pipe 11 are welded.
メタノール送液用配管支持部材を設置してメタノール送液操業を実施することにより、メタノール送液用配管支持部材の底面部は多少摩耗することはあったが、メタノール送液用配管自体には摩耗による損傷が生じることはなかった。 Although the bottom part of the methanol feed pipe support member was sometimes worn by installing the methanol feed pipe support member and performing the methanol feed operation, the methanol feed pipe itself was worn. No damage was caused by.
