High Quality Seamless Steel Pipe
PRODUCT DETAILS
Keyword: Steel Plate
General-purpose seamless pipes are made by hot rolling or cold rolling of high-quality carbon structural steels such as 10, 20, 30, 35, 45, 16Mn, 5MnV and other low-alloy structural steels, or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other combined steels. 10, 20 and other low carbon steel seamless pipes are mainly used for fluid conveying pipelines. Seamless tubes made of medium carbon steel such as 45 and 40Cr are used to manufacture mechanical parts, such as stressed parts of automobiles and tractors.
For general purpose seamless pipes, the strength and flattening tests shall be guaranteed. Hot-rolled steel pipes are delivered in a hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in a heat-treated state. Seamless tubes for low and medium pressure boilers: used to manufacture various low and medium pressure boilers, superheated steam tubes, boiling water tubes, water wall tubes and superheated steam tubes for locomotive boilers, large smoke tubes, small smoke tubes and arch brick tubes, etc.
High-quality carbon structural steel hot-rolled or cold-rolled (dial) seamless pipe. It is mainly made of No. 10 and No. 20 steel. In addition to ensuring the chemical composition and mechanical properties, hydrostatic tests, crimping, flaring, and flattening tests are required. Hot rolling is delivered in a hot rolled state, and cold rolling (dial) is delivered in a heat treated state.

Warehouse Storage
The raw material of seamless carbon steel pipe is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a critical issue. After the round tube blank is released from the furnace, it is pierced through a pressure punching machine. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls.
