ERW steel pipe/tube Electric Resistance Welding oil natural gas
Introduction “ERW steel pipe” is a straight seam resistance welded pipe, abbreviated as ERW. It is used to transport oil, natural gas and other vapor and liquid objects. It can meet various requirements of high and low pressure, and it occupies a pivotal position in the field of transportation pipes in the world. Welded pipes are round pipes welded by steel plates, which are divided into high frequency resistance welded pipes (ERW welded pipes), straight seam arc welded pipes (LSA... -
High frequency welded pipe Straight Seam Production manufacturer
Introduction High frequency welded pipe is based on solid resistance heat. Resistance thermal welding uses high-frequency current in the workpiece to heat the surface of the workpiece welding area to a molten or close to plastic state, and then applies (or does not apply) an upsetting force to the metal composite tube of this type of steel. The production speed of HFW steel pipe is fast, and the welding speed can reach 30m/min. It is made by melting the base material of the steel strip body, ... -
Welded steel pipe Straight Seam Carbon Steel Welded tube
Introduction Welded steel pipe refers to steel pipes with seams on the surface that are welded by steel strips or steel plates that are bent and deformed into round or square shapes. The blanks used for welded steel pipes are steel plates or strip steels. With the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds continues to improve, and the variety and specifications of welded steel pipes are ... -
Scaffolding steel pipe manufacturer hot dip GI
Introduction Scaffolding steel pipe is a working platform erected to ensure the smooth progress of various construction procedures. According to the erection position, it can be divided into outer scaffolding and inner scaffolding; each construction process. There are generally two kinds of steel pipes used to build scaffolding, one with an outer diameter of 48mm and a wall thickness of 3.5mm; the other with an outer diameter of 51mm and a wall thickness of 3mm; according to their location an... -
Petroleum steel pipe LSAW pipe oil seamless tube
Introduction Petroleum steel pipe is a long steel with a hollow section and no joints on the periphery. Petroleum cracking pipe is an economical section steel. The use of petroleum cracking pipes to manufacture annular parts can increase the utilization rate of materials, simplify the manufacturing process, and save materials and processing man-hours. For example, rolling bearing rings, jack sleeves, etc., have been widely manufactured with steel pipes. Petroleum cracking tubes are also indis... -
Seamless steel pipe galvanized carbon Weld Steel Seamless tube
Introduction Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and top pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. Special-... -
Precision seamless steel Pipe Cold Drawn Hot Rolled Tube
Introduction Precision seamless steel Pipe/tube is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipe have no oxide layer, bear high pressure and no leakage, high precision, high smoothness, cold bending without deformation, expansion It is mainly used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes or welded pipes. The chemical... -
Hot roll seamless steel pipe Cold Drawn Hot Rolled Precision
Introduction Hot rolling is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature. Hot-rolled seamless steel pipes are divided into general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. Parameter Item Hot roll seamless steel pipe ... -
Thick wall seamless steel pipe precision Carbon Steel Tube
Introduction The production process of thick-walled seamless steel pipes can be divided into four basic methods: cold drawing, cold rolling, hot rolling, and thermal expansion. Uses are divided into seamless steel pipes for structure; seamless steel pipes for transportation; seamless steel pipes for boilers; high-pressure seamless steel pipes for boilers; high-pressure seamless steel pipes for fertilizer equipment; seamless steel pipes for geological drilling; seamless steel pipes for oil dri... -
Small seamless steel Pipe cold drawn hot rolled precision steeltube
Introduction Seamless steel pipes with small outer diameters can be called small-diameter seamless steel pipes. Small-diameter seamless steel pipes can also be divided into: seamless small-diameter steel pipes and straight seam (also called welded) small-diameter seamless steel pipes. The outer diameter of the steel pipe is 89mm or less, 4mm or more; they can be collectively referred to as small-diameter seamless steel pipes. Parameter Item Small seamless steel Pipe/tube Standard ASTM, D... -
Large seamless steel pipe Cold Drawn Hot Rolled Precision tube
Introduction The main production processes of large-diameter seamless steel pipes in my country are hot-rolled large-diameter seamless steel pipes and heat-expanded seamless steel pipes. The maximum specification of heat-expanded seamless steel pipes is 325mm-1220mm and the thickness is 200mm.
