In industrial pipeline systems, LSAW and SSAW are two mainstream types of welded steel pipes. Although both belong to the category of arc welded steel pipes, they have significant differences in manufacturing process, structural performance and engineering applications. 1. Essential differences in manufacturing processes 1.
Alloy steel pipe is a high-performance pipe made of carbon steel by adding alloy elements such as chromium, molybdenum, nickel, and vanadium. Its excellent strength, high temperature resistance, corrosion resistance, and creep resistance make it occupy an important position in the fields of energy, chemical
As an important metal material, galvanized square tubes are widely used in construction, machinery, transportation, municipal administration and other fields due to their excellent corrosion resistance, high strength and aesthetics. 1. Material and steel grade The base material of galvanized square tubes is mainly carbon
Black square tube, also known as carbon steel square tube, is a hollow steel tube with a square or rectangular cross-section. It is named because it has a black metal surface without surface treatment (such as galvanizing or painting). Black square tubes are widely used
I. Materials and steel grades of seamless steel pipes and welded steel pipes Seamless steel pipes and welded steel pipes use different materials and steel grades according to their uses and requirements. Common ones include: 1. Seamless steel pipes Seamless steel pipes are usually used
Oil and gas line pipes are steel pipes specially used for transporting fluids such as oil and natural gas. As a key component for oil and gas transportation, it not only needs to withstand high pressure, corrosion, and low temperature, but also must meet the
The following are some commonly used grades and related introductions of carbon steel pipes in the world, classified according to common standards and countries: 1. United States (ASTM/ASME standard) ASTM A106 Purpose: Seamless carbon steel pipes widely used in high temperature and high pressure environments.
Coated steel pipe refers to a steel pipe with one or more layers of coating added to the surface of ordinary steel pipe to improve its performance. Coated steel pipe combines the strength of steel and the characteristics of surface coating and is widely used
Red plastic-coated fire fighting steel pipe is a steel pipe specially used in fire protection system. It has the characteristics of corrosion resistance, high temperature resistance and easy identification. It is widely used in automatic sprinkler fire extinguishing system, fire hydrant system, etc. The following
Seamless steel pipes are widely used in many industries such as petroleum, chemical industry, energy, and machinery manufacturing due to their high strength, good corrosion resistance, and strong pressure bearing capacity. In actual use, different industries and application scenarios have different requirements for the material
