Abstract
The utility model discloses a polytetrafluoroethylene anti-corrosion pipeline joint which relates to the anti-corrosion pipe joints of oil fields and chemical industry. The main body is a polytetrafluoroethylene pipe body 1, wherein an annular groove 2 is arranged along the circumferential direction of the outer wall of the pipe body, a thermal insulation layer 3 is arranged in the annular groove 2, a metal band 4 is arranged outside the thermal insulation layer 3, and a stabilizer rod 5 passes through the annular groove 2 and the thermal insulation layer 3 to be radially distributed along the pipe body. The outer wall of the pipe body 1 is also provided with sealing rings 6 which are positioned at both sides of the annular groove 2. When used, the joint is arranged in the interface of each of the two pipelines, the pipeline is sealed by the sealing ring 6 on the joint, and the stabilizer rod 5 threads out of a pipeline seam to realize the inner positioning operation of the joint. The polytetrafluoroethylene anti-corrosion pipeline joint can directly realize the sealing and the protection for the pipeline, and has the superior performance of pressure resistance, corrosion resistance, ageing resistance, strong acid resistance and strong alkali resistance; the pipeline is not influenced by the processing, such as welding, etc. and has good sealing performance and convenient installation.
Description
Technical field:
The utility model relates to the anti-corrosion pipe joint of oil field, chemical industry, is adapted at using in the rugged environment.
Background technique:
At present, the pipeline of common oil field, chemical industry has corrosion-inhibiting coating usually, in the pipeline welding process, because thermal strainization can make the surface anticorrosion pull-up fall, thereby destroy its antiseptic property, causes the pipe joint place easily to be corroded, and seepage takes place.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency that above-mentioned known technology exists, thereby a kind of anticorrosive PTFE pipe coupling is provided, and antiseptic property is good, long service life.
The purpose of this utility model realizes in the following way:
This anticorrosive PTFE pipe coupling main body is the body 1 of teflon, wherein: body 1 outer wall along the circumferential direction has a circular groove 2, have one deck thermal-protective coating 3 in the circular groove 2, the outer strip metal bands 4 that have of thermal-protective coating 3, rear stabilizer 5 pass circular groove 2 and thermal-protective coating 3 along the body radially direct.
Also have seal ring 6 at body 1 outer wall, be positioned at the both sides of circular groove 2.
Rear stabilizer 5 can be a drift bolt, passes outwards through circular groove 2 and thermal-protective coating 3 from the lining.
During use, this joint is contained in two pipe joints, 6 pairs of pipelines of the seal ring on the joint seal, and rear stabilizer 5 passes the positioned internal that pipeline joint-seam can be realized joint.
The utility model compared with prior art has following advantage:
Owing to adopt the anticorrosive PTFE joint, can directly realize the sealing and the protection of pipeline, withstand voltage, corrosion-resistant aging quality and anti-strong acid, highly basic function admirable, and pipeline do not welded the influence that waits processing, and good airproof performance is convenient to installation.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural drawing.
In Fig. 1: 1 body; 2 circular grooves; 3 thermal-protective coatings; 4 metal tapes; 5 rear stabilizers; 6 seal rings.
Embodiment:
Embodiment sees Fig. 1: the utility model main body is the body 1 of teflon, along the circumferential direction have a circular groove 2 at body 1 central outer wall, have one deck thermal-protective coating 3 in the circular groove 2, the outer strip metal bands 4 that have of thermal-protective coating 3, stabilized metal bar 5 pass circular groove 2 and thermal-protective coating 3 along the body radially direct.Seal ring is respectively established two in circular groove 2 both sides.
During installation this joint is contained in two pipe joints, 6 pairs of pipelines of seal ring of four seal on the joint, and rear stabilizer 5 passes the positioned internal that pipeline joint-seam can be realized joint.
