About this topic pipe insulation joint protection, insulation joints With our experience and access to a lot of information on the topic of insulation joints to protect the pipeline has its own point of view, you may find some helpful analysis of the topic, (1) can not have an additional vertical pipe resistance of pipe fittings (such as union section, expansion joints, valves, flanged), or they must use metal wire jumper. (2) There must be a good pipe insulation coating gas pipeline insulation joints, as little coating defects. It should not leak those devices will increase the load has been grounded contact, such as grounding devices, pipes, casing, valves, bearings, nor can be electrically connected to each other with them. (3) In the short pipe in the ground and by the end of the longer range of pipe insulation should be installed to protect endpoints joints, or in parallel with additional cathodic protection stations to limit the scope of protection of power. Measures to achieve low resistance meets this paper discusses only the insulated joint protection of the pipeline on behalf of my factory own point of view, does not guarantee one hundred percent accuracy. An insulating layer sandwiched between the upper and lower rigid conduit pipe insulation joints between the upper and lower rigid insulation joints, joints between insulation voltage insulation between the manufacturer and the catheter jacket, down jacket and pipe together as one, through a certain process of internal and a pressure seal, forming a seal between the outside and insulated from each vertical conduit; installation directly welded to both ends of the pipe end. Vintage insulating flange is constituted in a plane between two flanges welded to install the fastening flange of the insulating sheet and the insulating sleeve is connected with the installation of the insulating shim screw bolts. Generally ground installation, and the installation process is complex, requiring high insulation performance by insulating gasket materials and installation techniques impact, large-diameter insulated joint is unstable prices, especially for natural gas sealing performance poor insulation joints and insulation joints and insulation method Portland compared to just pipe welded on both sides, the process is simple, sealing, rigid, especially the insulation performance is more stable, both on the ground is also suitable for installation underground installation, use temperature -40 ~ 1200C, for medium installation oil and gas, water, chemicals, coal, coal slurry, etc., has become insulating flange replacement.
