What are the grades of rust removal for anti-corrosion steel pipes?
Anti-corrosion steel pipes refer to steel pipes treated with anti-corrosion technology, which can effectively prevent or slow down corrosion caused by chemical or electrochemical reactions during transportation and use.November 22, 2023
Why should we consider machinability during annealing and normalizing?
Normalizing is to heat steel pipes (such as seamless pipes and welded steel pipes) to 30 to 50 degrees above Ac3 or Accm, and then cool them at a slightly higher cooling rate than annealing after insulation.November 21, 2023
How to distinguish steel pipe piles and steel sheet piles?
Steel pipe piles and steel sheet piles are both structural members used in construction projects, but they differ in shape, use and installation methods.

What is a straight seam welded pipe production line?
The straight seam welded pipe production line is a process in which the steel plate to be welded is heated or pressurized, or both are used, with or without filling materialNovember 13, 2023
What is cold treatment of stainless steel pipes?
What is cold treatment of stainless steel pipes?
Both stainless steel seamless steel pipes and stainless steel welded steel pipes can be cold processed - cold rolled and cold drawn to meet higher requirements for cold processed products.November 8, 2023
Characteristics of OCTG pipes
Oil well pipes (including OCTG casing), also known as special oil pipes, are steel pipes specially used for oil and natural gas extraction. Most of them are seamless pipes, but welded pipes also account for a considerable proportion.November 3, 2023
How is smls pipe stored and saved?
The site or warehouse for steel storage should be selected in a clean and well-drained place, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed on the site to keep the steel cleanNovember 2, 2023
