Abstract
The utility model discloses a stainless steel joint that is protected from heat, including one section stainless steel steel pipe, the both ends of stainless steel steel pipe have from the inclined plane of inner wall to the outer wall, and the contained angle of inclined plane and inner wall is at 40 -60, the wherein one end at the both ends of stainless steel steel pipe is big than the internal diameter of the other end. The utility model discloses based on deformed steel welding technique, adopted have different non -corrosibilities can seamless stainless steel pipe do and connect, the design conception through being protected from heat simultaneously, better solution anticorrosive steel pipe connect a difficult problem to anticorrosive steel pipe's life has been prolonged greatly. Use in the seamless stainless steel pipe design of surface machining fine screw thread and slot in the design, effectually increased interior anticorrosive coating in the bonding force and the intensity in here, corrosion prevention medium infiltration deformed steel's welding seam department.
Description
Technical field
The utility model relates to pipe technology field, specifically refers to a kind of connect for anti-corrosive steel tube stainlessThe steel joint connecting structure that is Protected from Heat.
Background technology
Along with the fast development of China's economy, the consumption of anti-corrosive steel tube is increasing. Steel pipe corrosion-proof technologyHave a connectivity problem that greatest problem is exactly pipeline, existing method of attachment meeting destroys corrosion-inhibiting coating,Therefore have that antiseptic property is undesirable, poor sealing, high in cost of production defect, thereby restricted greatlyA large amount of uses of anti-corrosive steel tube.
Based on above reason, be necessary to develop a kind of method of attachment or structure of new anti-corrosive steel tube.
Utility model content
The object that the utility model is wanted is to overcome existing steel pipe corrosion-proof pipeline and connects the defect existing, and carriesSupply a kind of moderate cost, can weld and do not affect the connection for anti-corrosive steel tube of antiseptic property notThe rust steel joint that is Protected from Heat.
The technical solution of the utility model is:
A kind of stainless steel joint that is Protected from Heat, comprises one section of stainless-steel pipe, it is characterized in that,The two ends of described stainless-steel pipe have the inclined-plane from inwall to outer wall, inclined-plane and inwallAngle is at 40-60 °, and the wherein one end at the two ends of described stainless-steel pipe is compared with in the other endFootpath is large.
In the two ends of described stainless-steel pipe, have compared with one end of large diameter and be provided with screw thread.
In the two ends of described stainless-steel pipe, have compared with the inwall of one end of large diameter and be provided withGroove, described groove is positioned at the end place of described screw thread.
In above-mentioned design, the setting on 40-60 ° of inclined-plane is for the ease of of the present utility modelRust steel be Protected from Heat between joint with and with the welding of anti-corrosive steel tube, have compared with one of large diameterEnd is for being connected with anti-corrosive steel tube, and larger internal diameter is convenient to the processing processing of corrosion-inhibiting coating.Arranging of fine thread can make corrosion-inhibiting coating have larger surface area, increases bonding forceAnd intensity, arranging of groove can separate corrosion-inhibiting coating region and the uncoated joint that is Protected from HeatRegion, the destruction to corrosion-inhibiting coating region reduce to be situated between prevents from being Protected from Heat while welding between jointWashing away of confrontation steel pipe.
Anti-corrosive steel tube is installed while connection, by two stainless steels be Protected from Heat the internal diameter of joint large oneEnd is connected with anti-corrosive steel tube respectively, be Protected from Heat little one end pair of internal diameter of joint of two stainless steelsWeldering.
The utility model, taking deformed steel solder technology as basis, has adopted different anti-corrosive propertiesThe stainless-steel seamless pipe of energy is made joint, simultaneously by the Design Conception being Protected from Heat, preferablySolve anti-corrosive steel tube and connected a difficult problem, thereby greatly extended the service life of anti-corrosive steel tube.In design, apply the design side of stainless-steel seamless pipe inner surface processing fine thread and grooveCase, has effectively increased interior anticorrosive coat bonding force and intensity herein, prevents that corrosion is situated betweenMatter is infiltrated the commissure of deformed steel.
Brief description of the drawings
Fig. 1 is the be Protected from Heat longitudinal sectional drawing of joint of stainless steel.
Fig. 2 is that be Protected from Heat joint and seamless steel pipe of stainless steel welds and carry out the vertical of inner wall anti-corrosiveTo profile.
Detailed description of the invention
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, of the present utility model to describe in detailTechnical scheme.
Embodiment:
The joint that is Protected from Heat of stainless steel of the present utility model as shown in Figure 1, comprise one section stainlessSteel steel pipe 100, the two ends of stainless-steel pipe have the inclined-plane from inwall 110 to outer wall 120101, the angle of inclined-plane and inwall is at 60 °, and the wherein one end at the two ends of stainless-steel pipeThe internal diameter of the other end is large, generally has compared with one end of large diameter and is provided with screw thread 102, the using up of screw threadThe inwall at head place is provided with groove 103.
Its processing preparation process is as follows: get the stainless-steel pipe of one section of 130mm, at eachThe inclined-plane that the processing of section two ends is 60 °, wherein one end adds internal diameter within the scope of mouth of pipe 30mmWork expands 1-2mm, and the Surface Machining fine thread expanding; At inner surface fine threadA wide 2mm of end place, inner end processing, the groove of dark 0.2mm.
As shown in Figure 2, when anti-corrosive steel tube is made, stainless steel is Protected from Heat and connects 100 internal diameters expansionsLarge one end with weld together with bore steel pipe 200 pipe ends; Require corrosion-inhibiting coating 300 completePortion cover weld seam 400, and all cover stainless steel be Protected from Heat joint surface screw thread 102 andThe groove 103 of screw thread inner end, the stainless steel part beyond joint screw thread and groove that is Protected from Heat must not haveCorrosion-inhibiting coating, to ensure that corrosion-inhibiting coating of steel pipe is not damaged by electric welding high temperature.
More than show and described general principle of the present utility model, principal character and this realityBy novel advantage. The technical staff of the industry should understand, and the utility model is not subject to above-described embodimentRestriction, that in above-described embodiment and description, describes just illustrates principle of the present utility model, notUnder the prerequisite of disengaging the utility model spirit and scope, the utility model also has various changes and modifications,These changes and improvements all fall within the scope of claimed the utility model.
