ST42 Carbon steel pipe
PRODUCT DETAILS
Keyword: Steel Plate
The tensile strength of ST42 Carbon Steel Pipe shall not be less than 42kgf/mm2, which is 420MPa.
ST42 Carbon Steel Pipe is a German standard seamless steel pipe, which is widely used. German standard seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for fluid transportation .
According to different uses, it can be supplied in three categories: a. according to chemical composition and mechanical properties; b. Supply according to mechanical properties; c. Supplied as per hydrostatic test. The steel pipes supplied according to class a and b shall also undergo hydrostatic test if they are used to withstand liquid pressure. 3. Seamless tubes for special purposes include boiler seamless tubes, chemical and electric power seamless tubes, German standard seamless tubes for geology and seamless tubes for petroleum.
The German standard seamless steel pipe has a hollow section, and is widely used as a pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steels such as round steel, steel tubes are light in weight when their bending and torsional strength are the same, so they are a kind of steel with economic section.
German standard seamless steel pipe materials: ST33, ST37, ST37.2, ST35.8, ST35.4, ST35.8, ST35.8, ST42, ST42.2, ST45.8, ST45.8, ST45.4, ST52.4, ST52.3, ST52, etc.

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.
1. Seamless steel pipe for structure (GBT8162-2008). Mainly used for general structure and mechanical structure. Its representative material (brand): carbon steel, 20, 45 steel; alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc. 2. Seamless steel pipes for conveying fluids (GBT8163-2008). It is mainly used for conveying fluid pipelines in engineering and large-scale equipment. The representative material (grade) is 20, Q345, etc. 3. Seamless steel pipes for low and medium pressure boilers (GB3087-2008) are used to manufacture various structures of low and medium pressure boiler superheated steam pipes, boiling water pipes and superheated steam pipes, large smoke pipes, small smoke pipes and arch bricks for locomotive boilers Hot-rolled and cold-drawn (rolled) seamless steel pipes of high-quality carbon structural steel for pipes. The representative material is 10, 20 steel.
