1. Hot-rolled (extruded) carbon steel seamless steel pipe: round tube billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube removal → sizing (or reducing) → cooling → straightening → water Pressure test (or flaw detection) → marking → storage...
The pipe is then pulled through a ring die or bell and the pipe is welded by pressing the edges together at a high temperature. The pipe OD is reduced and the wall thickness is achieved in a stretching mill. A saw cuts the pipe to length and the pipe enters a sizing mill that ...
1. Production process of hot-rolled seamless steel pipe: tube billet → heating → perforation → three-roller/cross-rolling & continuous rolling → de-pipe → sizing → cooling → straightening → hydraulic test → marking → seamless steel pipe with leverage effect detected. 2. Production proce...
using hot rolled steel pipe billet to make heating and piercing, elongating, sizing and stranghtening, cooling, finally hollow bars finished, this is the type most commonly used. Because it is hot rolled, so cost is lowest, but it is suit for large quantity, for small...
common welded pipe is used as the base pipe and the pure stainless steel pipe is used as the outer pipe is formed, and stainless steel/carbon steel composite pipes for the bridge guardrail with different specifications are manufactured by straightening, sizing, port processing and surface polishing...
B: Production process of hot-rolled seamless steel pipe: Tube billet → heating → perforation → three-roller/cross-rolling & continuous rolling → de-pipe → sizing → cooling → straightening → hydraulic test → marking → seamless steel ...
billet for drilling, forming a steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the sizing machine drill bit. After the steel pipe is sized, it enters the cooling tower and is cooled by water spray. After cooling, the steel pipe n...
The sizing machine uses a conical drill bit to rotate at high speed into the steel billet for drilling, forming a steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the sizing machine drill bit. After the steel pipe is sized, i...
Stainless Steel Pipe ASTM B-241 Pipe Aluminum Pipe ASTM A-106 Pipe This specification covers carbon steel pipe for high-temperature and high-pressure service. This pipe is suitable for welding, bending, flanging, and similar forming operations. Sprinkler Pipe The sizing of fire sprinkler pipe is...
The weld seam is ironed and pipe passes through the cooling section. Then in sizing section, pipe is formed to specified size and converted into specified shape. After sizing, pipe is cut to required length by using flying saw cut off equipment and delivered to col...
