"Contact: Li Chunpeng Tel: QQ:1327077391 13930752103" L360 anticorrosive insulating joint is also referred to as having pipe insulation performance of buried steel pipeline joint requirements of the sealing performance, strength properties and electrical corrosion protection required by the. The utility model comprises a component, an insulating board, a filler, a sealing ring, a short tube, etc.. The insulation joint is improved according to the replacement of insulating flange problems in use, the pressure is an important essential element of cathodic protection system of steel pipe in the cathodic protection system is widely used in steel pipe.
With the development of sour gas field, gas pipeline is facing more and more severe corrosive environment. A lot of gas pipeline failure due to serious corrosion, and even cause an explosion, threatening personal safety, pollution of the environment, the consequences are very serious. At the same time, the development of the steel pipe manufacturing industry Xu Su, stainless steel composite steel pipe because of its carbon steel or alloy steel mechanical properties, but also has the advantages of corrosion resistance of stainless steel, has been widely used.
L360 its main chemical components include C0.30, Mn1.25, P0.030, S0.030, and its yield strength 360Mpa, tensile strength 460Mpa, elongation of 9%. The microstructure of L360 steel is pearlite and ferrite. L360 steel has the title of anti sulfur steel. Marked its corrosion resistance. L360 material is mainly used in the field of central heating, with high compressive strength and low temperature toughness and excellent welding performance. Gas, water and oil transportation in the oil and gas industry due to the L360 pipeline. So L360 insulation joint is widely used in oil, natural gas industry in the gas, water, oil pipeline.
Therefore, L360 anti-corrosion insulation joint is more suitable for oil and gas pipelines in the application of insulation joints
