Product Description

Billets and coils are delivered to the pipe mill ready to be made into carbon steel pipe. Depending on the capabilities of the pipe mill and the end use of the final product, the casts will be formed into pipe by means of four distinct different manufacturing.Seamless carbon steel pipe has, as its name implies, no longitudinal weld seam. It is, in essence, one solid homogeneous piece of steel. A solid billet is simply heated and then stretched over a series of mandrels until the pipe has achieved its desired diameter and wall thickness.
1. The main production process of hot-rolled seamless steel pipe (main inspection process):
Tube blank preparation and inspection→tube blank heating→piercing→tube rolling→steel reheating→fixed (reduced) diameter→heat treatment △→finished tube straightening→finishing→inspection (non-destructive, physical and chemical, Taiwan inspection)→warehousing
2. The main production process of cold-rolled (drawn) seamless steel pipes:
Billet preparation→pickling lubrication→cold rolling (drawing)→heat treatment→straightening→finishing→inspection
The fluid pipeline is a hollow section steel pipe without weld from beginning to end. The steel pipe is a hollow section, which is used as a pipeline to transport a large amount of oil, natural gas, natural gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter and has the same bending and torsional strength. It is a kind of economical section steel, which is widely used in the manufacture of structural and mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle and so on. Scaffolds and steel scaffolds for construction. We also have other similar steel pipes, such as structural steel pipe, boiler steel pipe, polished steel pipe, etc. (such as API 5L hot rolled steel pipe, API 5L grade B Sch 40 80 160, API 5lx52 seamless steel pipe, API 5lx52 seamless steel pipe)
When seamless welded pipes are used as fluid transmission pipes, they have different requirements from ordinary steel pipes:
1. No leakage is allowed in the weld. For the welded pipe required by API, the weld of each welded pipe also needs ultrasonic flaw detection and hydrostatic test;
2. When transporting corrosive chemical solutions, the inner walls of all steel pipes must be subject to anti-corrosion treatment;
3. All fluid pipes need internal deburring to reduce fluid transmission resistance.
Hot rolled and extruded (1-3) steel pipe
2. Cold drawn (rolled) steel pipe 3-10.5m
1. When the wall thickness is less than or equal to 15mm, it shall not be greater than 1.5mm/m
2. When the wall thickness is > 15mm, it shall not be greater than 2.0mm/m
3. When the outer diameter is greater than or equal to 351mm, it shall not be greater than 3.0mm/m
(outer diameter and wall thickness) * wall thickness * 0.02466 = kg / M (weight per meter)
