Abstract
The utility model discloses a kind of cargo oil system pipeline installation pipe snap ring, for large-scale VLCC Main deck cargo oil system, be positioned on Main deck unit pipe support, novel snap ring is by the sheet material of one fixed width and three pieces of polyethylene cushion blocks, and four fixing bolts are formed; Wherein, three pieces of polyethylene cushion blocks are between snap ring and cargo oil system pipeline, and snap ring is fixedly mounted on above unit pipe support by four fixing bolts.The utility model fundamentally changes existing pipe and fixes the form using snap ring, increase pipe installation strength, and enhance in installation process and controllability and adjustable type are installed, form snap ring insufficient strength is in the past avoided to cause oily medium pipeline, fix because of pipe clamp the coupling incessantly caused to damage, thus the serious consequence causing Cargo Oil to reveal.The utility model solves heavy caliber pipe fixed tube card insufficient strength, the problems such as construction quality is not good.Strengthen adjustable, reduce difficulty of construction, improve the service property (quality) of pipeline in construction quality and system operation.
Description
Technical field
The present invention relates to a kind of pipeline road snap ring, more particularly, relate to and installing for large-scale VLCC boats and ships Main deck cargo oil system pipeline, pipe fixedly uses snap ring.
Background technique
In the large-scale VLCC shipbuilding process of prior art, Main deck cargo oil system pipeline, bore is large, and system pipeline arranges expansion bend.Pipe bore is large, and the snap ring existing form intensity of fixing tube is not good; The expansion bend that pipeline is arranged, " concentricity " of two ends institute installation pipeline requires very high, and reason needs to ensure that the close property requirement of rear pipe-line system installed by annex.There is not the inching of pipe mounting point in existing snap ring.Frequent needs are modified to the large-scale outfititem supporting pipeline or on-the-spot adjustment, and not only adjustment process exists potential safety hazard, and construction is got up very difficult, causes very large construction load to site operation.
The difficult point of this problem is, large-scale VLCC boats and ships Main deck cargo oil system pipeline, bore large (conventional design is the pipe of external diameter Φ 660*12.7), and pipe weight is large, adjusts pipe " concentricity " difficulty in installation process; In system work process, system pipe stressing conditions is serious, and the pipe snap ring of prior art, often because intensity is not good, causes the damage of pipe and annex.
Summary of the invention
The present invention for better can fix large-scale VLCC boats and ships Main deck cargo oil system pipeline, and in system pipeline installation process, makes the mounting point of pipe have certain controllability.Avoid because the damage of snap ring fixed by the bad caused pipeline fittings level pipe of this system pipeline installation quality.Namely the intensity that snap ring fixed by pipe is enhanced; " concentricity " requirement between better guarantee tube and tube, improves system pipeline installation quality again.Further, improve in the operation of this system works of boats and ships, the safety index of boats and ships and personnel.
In order to achieve the above object, the invention provides a kind of installation for large-scale VLCC Main deck cargo oil system pipeline and fixedly use snap ring.Cargo oil system pipeline installation pipe snap ring of the present invention, comprising a centre is the snap ring that semicircle both sides transit to horizontal segment, and described horizontal segment arranges two bolts hole fixed with bolt matching straight down; On left and right, upper three directions of described semicircle, inner side is offered hole body respectively and is inlayed and establishes polyethylene cushion block.
Under optimal way, be connected by vertical section and arc transition mode between described semicircle with described horizontal segment.
The present invention installs at large-scale VLCC boats and ships Main deck cargo oil system pipeline and in system operation, takes this invention pipe to fix pipe clamp for fixed system pipeline.Through on probation, the invention solves the situation that the intensity of prior art pipe clamp is not good, and improve the adjustable type of pipe in pipeline installation process, while reducing builder's site operation difficulty, improve the installation capability of construction quality and system cloud gray model.
Accompanying drawing explanation
Fig. 1 is Novel pipe clamp detail drawing.
Fig. 2 is Main deck cargo oil system pipeline installation form (new-type, old-fashioned pipe snap ring contrast figure).
In figure, 1, snap ring, 2, polyethylene cushion block, 3, bolt, 4, pipeline, 5, deck unit pipe holder
Embodiment
As shown in Figure 1, it is the middle snap ring 1 for semicircular arc of plane that Novel pipe clamp comprises two ends, and inner left and right, upper three directions arrange three polyethylene cushion blocks 2 to semicircle snap ring 1, are used for holding out against Cargo Oil pipeline 4.As shown in Figure 2, in use, half-round clamping ring 1 two ends are fastened on deck unit pipe holder 5 by bolt 3 this device, and three the polyethylene cushion blocks 2 being arranged on half-round clamping ring 1 inside apply pressure to Cargo Oil pipeline 4 simultaneously.So just, make two ends fixing bolt 3 be fixed on firmly on deck unit pipe holder 5 by Cargo Oil pipeline by snap ring.
In figure, middle transit to horizontal segment 11 for semicircle both sides, horizontal segment 11 arranges two supporting fixing bolts hole with bolt 3 straight down; Left and right, upper three directions of semicircle are offered respectively hole body and inlay and establish polyethylene cushion block 2.Be connected by vertical section 12 and arc transition mode between semicircle with described horizontal segment 11.
A kind of embody rule at large-scale VLCC boats and ships, the present invention large-scale VLCC boats and ships Main deck cargo oil system pipeline installs fixing snap ring, and employing thickness is 30mm, and the steel plate of width 80mm is snap ring body, bolt/the mother of M30 is fixing bolt, realizes pipeline fix by adding three polyethylene cushion blocks.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
Claims (2)
