　   Product type: pipe insulation support

　　Main properties: insulation and long-term chemical corrosion resistance, excellent wear resistance and good impact resistance, as well as mechanical, thermal impact, stress resistance.

　　Scope of application:

　　oil, natural gas, coal gas, industrial chemical liquid pipeline construction across highways, rivers, Bridges, mountains, etc., is the cathode protection measures indispensable cathodic protection series of products in the important products.

　　The pipe insulation support frame is mainly used between the pipe and the sleeve. On the one hand, it plays a supporting role in the process of the main pipe into the sleeve to avoid damage to the sleeve; on the other hand, it plays a insulating role to make the main pipe and the sleeve insulated from each other, which is also the requirement of cathodic protection. This product has been tested repeatedly and used on site. It can fully meet the requirements of site use, and has been unanimously approved and praised by users and owners. It has been selected for many times in the construction of oil and gas pipelines.

Detailed introduction:

　　Insulation support is also called insulation support, generally divided into large and small pieces, pipe diameter in the following 600 with small pieces, in a particularly large (generally refers to the diameter of more than 500 pipe) support added metal hoop, in order to strengthen the support and pipe > pipe tightness. Jiaozuo ladbrokes light alloy co., LTD., the production of useful stents in main > series pipe insulation pipeline crossing highway, railway, such as pipeline > pipeline crossing river, competent for segregation and casing, its material is high density polyethylene, insulation and long chemical corrosion resistance, excellent wear resistance and good impact resistance, and mechanical, thermal shock, The main quality and technical indexes of the stress performance have reached the quality and technical standards of the same industry abroad. Its high strength mechanical bearing capacity and its versatility, and good cost performance and is widely used, quality and technical standards have all reached China petroleum pipeline company pipeline technology research center of the directional crossing pipe racks standards > pipe insulation, the main quality of quality and technical indicators have reached the German industry technical standards.

　　Characteristics of pipe insulation support:

　　1, wide application: the company's production of pipeline insulation support, widely used in oil, natural gas, gas, industrial chemical liquid pipeline construction across the highway, rivers, Bridges, mountains, etc., is the cathode protection measures indispensable cathodic protection series of products in the important products. Suitable for all kinds of pipe diameter specifications, our company can also according to customer needs to manufacture special specifications of insulation support.

　　2, good robustness, the product has double reinforcement measures, four tighten line, scientific and convenient to support strong fastening on the pipeline, thoroughly solved because of the large diameter pipeline construction, through the long distance and easily to support mobile or single fastening is damaged, make the support block falls off phenomenon, to ensure construction quality.

　　3. Solve the construction difficulties, speed up the construction and improve the construction quality: the company fixed the 5mm rubber plate in the inner wall of the insulation support according to the construction design requirements, so as to prevent the damage of the anticorrossment layer outside the pipeline during the construction, which can effectively improve the construction speed and quality, and meet the design requirements. Ensure the construction quality and reduce the construction cost.
