Duplex Stainless Steel Seamless Pipe

Duplex stainless steel is composed by any two phase organization of the austenite, ferritic and martensite about half and half of the proportion. But it usually refers to the austenitic – ferrite duplex stainless steel, it possesses both austenite and ferrite stainless steel characteristics, which has the comprehensive mechanical properties of high strength and high toughness; good resistance to crevice cxjrrosion, pitting corrosion and stress corrosion cracking ability; good resistance to uniform corrosion ability; good welding performance, small thermal cracking tendency; high coefficient of thermal conductivity, small coefficient of linear expansion etc. It is widely used in methanol production of tubular reactor catalytic […]

Carbon Steel pipe Bollards – Steel Pipe Security for Building Perimeters

Why choose steel pipe bollards Steel posts are one of the simplest, most cost-effective ways to offer protection for buildings and pedestrians from vehicle collisions, as both a physical and visual barrier. Steel bollards can be installed in any surface, indoors or outdoors, to prevent entry from errant vehicles, secure vulnerable areas, and protect site assets. As the population, especially in urban centers, continues to grow, so too does the number of vehicles on the road. With the increase of drivers and cars in and around cities, the likelihood of accidents and collisions has gone up as well. Properly planned […]

Line pipes for the oil and gas

Line pipe is a type of pipe that is manufactured from high strength carbon steel. It is typically made according to metallurgical specifications that were developed by the American Petroleum Institute (API). Line pipe can be used to build pipelines that transport a variety of resources including natural gas, oil, petroleum, and water. Steel line pipe has been used successfully for decades now in the transportation of gases, flammable liquids and solids. Given the high pressure levels frequently involved in the transportation of these media, steel is the optimum pipe material and it remains unparalleled in terms of safety and […]
