steel pipe

 ERW steel pipe, which is short for electric resistance welded steel pipe, is widely used for low pressure liquid delivery, such as water, gas and oil field, oil drilling and machinery manufacturing, etc. Today, we’ll talk about most common seen surface treatment for electric resistance welded steel pipe. First comes fusion bond epoxy, also known as FBE coating, which is widely used to protect steel pipe used in pipeline construction from corrosion. Working temperature for FBE coated steel pipe can up from 180? to 250?. Then comes varnish coating. Varnish coating is the most general surface treatment for steel pipe. General varnish coating is just an oil-liked coating on pipe surface and have strong anti-corrosion effect. For industrial steel pipes, varnish steel pipes is needed. Another surface treatment for ERW steel pipe is PE. Both PE and 3PE is common seen ways. PE coated steel pipe is widely used for liquid transportation usage pipe. Another surface treatment for ERW steel pi...

 A flange is a disc-shaped part that is most common in plumbing engineering.It is the part that connects the pipes to the pipes. Connect to the pipe end. There are holes on the flanges for bolts to connect the two flanges tightly. The flanges are sealed with gaskets. The main factors affecting flange sealing are: bolt preload, sealing surface form, gasket performance, flange stiffness and operating conditions. 1.Form of sealing surface 1)Flat type: simple structure, convenient processing, convenient for anti-corrosion or lining. However, the gasket is easy to extrude and not easy to be compressed. It is used in low pressure, small size, non-toxic, and low sealing requirements. 2)Concave-convex type: good neutrality and good sealing performance, suitable for medium pressure and high temperature occasions. 3)Tongue and groove type: good neutrality, reliable sealing, small gasket width, and small pressing force. It is suitable for flammable, explosive, toxic and high pressure occasion...

 Submerged arc welding is an important welding method. Its inherent advantages of stable welding quality, high welding productivity, no arc and little smoke make it an important steel structure in the production of pressure vessels, pipe sections, box beams and columns. the main welding method.In recent years, although many new welding methods with high efficiency and high quality have appeared successively, the application field of submerged arc welding has not been affected in any way. From the perspective of the weight share of deposited metal for various fusion welding methods, submerged arc welding accounts for about 10% and has not changed much over the years. Therefore, in the production process of SSAW steel pipe, the following three process defects often occur. 1)Defects in the handling of heated parts.In the thermal process, proper and effective heat treatment heating equipment and heating medium must be selected. If the heating temperature exceeds the process requirement...
