Carbon steel pipes are made of steel ingots or solid billets through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The raw material of 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
API 5CT CASING AND TUBING Casing pipe is most often used in underground construction projects to encase or protect utility lines from being damaged. Once a well has been drilled, if it is to become a production well, the well must undergo completion. While drilling a well cuts through the rock formations and allows drilling engineers to reach the reservoir below, the raw sides of the well cannot support themselves. Similar to the bones of your spine protecting the spinal cord, casing is tubing...

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. Steel Pipe can be divided into Cold Drawn Smls Steel Pipe Hot Rolled Smls Steel Pipe Galvanized Steel Pipe. Features of ERW pipe Low cost: the low raw material cost and manufacturing cost make it prices more competitive than longitudinal seam submerged-arc welded pipes and seamless pipes. High Weld Seam Security: As a result of...

Spiral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding, and welding them into a spiral. The SSAW pipe is widely used in long distance pipeline project for transmission of oil, natural gas, water as well as coal gas, and also is used in all kinds of engineering, such as chemical industry, electric power, irrigation, construction and piling etc. Advantages of ssaw steel pipe (1) The use of steel...
PPGI is Prepainted Steel Coil, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip Galvanized Steel Coil substrate. Zinc coated steel substrate for PPGI is typically produced on a continuous galvanizing line (CGL). The CGL may include a painting section after the hot dip galvanising section, or more commonly the metallic coated substrate in coil form is processed on a separate continuous paint line (CPL). Metallic coated steel is cleaned,...
