ASTM A335 Pipe is a seamless ferritic alloy-steel Pipe for high temperature service.
ASTM A333 Gr.6 + ASME SA333 Gr.6
The main components of A333 seamless steel pipe include iron, carbon, chromium, nickel, manganese and other elements.
ASTM A335 P11+ASME SA335 P11
ASTM A335 Pipe is a seamless ferritic alloy-steel Pipe for high temperature service. Pipe of this specification are suitable for bending, flanging, and similar forming operations, and for fusion welding.
ASTM A335 P22+ ASME SA335 P22
12Cr1MoVG seamless steel pipe
Seamless steel pipe is made by perforating a whole round steel. It has no welds on the surface and a hollow cross-section structure. It is widely used in fluid transportation, machinery manufacturing and other fields.
15CrMoG Seamless Steel Pipe
DIN 1629 Seamless Steel Pipe
DIN 1629 seamless steel pipe its main grades are St37.0, St44.0, St52.0, DIN 1629. Generally, the DIN 1629 standard is not limited to the working pressure value, and the working temperature is limited to below 300 ℃.
Galvanized Steel Pipe
Galvanized pipe Galvanized steel pipe, also known as galvanized pipe, is divided into two kinds of hot dip galvanized and electro galvanized. The hot-dip galvanized layer is thick, the coating is uniform, the adhesion is strong, and the service life is long. Zinc is commonly used to galvanize or coat these metal tubes. The galvanizing process for steel pipes involves immersing the metal pipe in a bath containing 450 degrees Fahrenheit molten zinc. After a few minutes, the hot-dip galvanizing process is complete.
Resistance Welded Pipe ERW
Resistance welded pipe ERW is formed by hot rolled coil through forming machine. The skin effect and proximity effect of the high frequency current are used to heat and melt the edges of the tube blank. Pressure welding is carried out under the action of squeeze rollers. Realize production. The production process of welded steel pipes is simple, the production efficiency is high, the varieties and specifications are many, and the equipment is few, but the general strength is lower than that of seamless steel pipes.
LSAW Pipe
The longitudinal submerged arc welded pipe is made of steel plate as raw material, which is formed by a forming machine, and then double-sided submerged arc welding is carried out. Through this process, the LSAW pipe will have excellent ductility, toughness, uniformity, plasticity and good sealing performance. The production equipment can be produced quickly, easy to replace, and the product specification range of LSAW pipe is large. The production line can produce welded pipe diameter 406-4500mm, wall thickness 8mm-100mm.
DIN 17175 Seamless Steel Pipe
DIN 17175 is suitable for seamless pipes and is used in the construction of boilers, pipelines, pressure vessels and equipment. The maximum temperature can reach 600 ℃. At the same time, under high pressure, the total stress and related fouling conditions can increase or decrease the temperature limit.
