Characteristics of welded pipes

Date:2024-04-02View:73Tags: welded pipes,ERW pipes

Welded pipe is a metal pipe made by welding. Compared with ordinary steel pipes, it has the following characteristics:


welded pipes


1. High strength: Welded pipes are made of high-strength steel and have excellent load-bearing capacity.


2. Good corrosion resistance: Because the surface of the welded pipe has been treated, it can effectively resist the erosion of the external environment and can be used for a long time in harsh working environments.


3. Good processability: Welded pipes are processed using welding technology and have good processing performance, and can be processed into different shapes and sizes according to different needs.


4. Long service life: Because welded pipes have excellent corrosion resistance and high strength, they generally have a long service life and are widely used in construction, manufacturing and industrial fields.


Generally, welded pipes have high precision, uniform wall thickness, high internal surface brightness, high pipe density (the surface grade of the steel plate determines the pipe surface brightness), and can be of any length. Therefore, in the application of high-precision, medium and low-pressure fluids, its economy and aesthetics are reflected. The production process of welded pipe is simple, the production efficiency is high, the cost is low, and it develops rapidly. Welded pipes are steel pipes made by bending steel strips or steel plates into circles or squares and then welding them.


According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, etc.


Electrically welded pipes: used in China's oil drilling and machinery and equipment manufacturing industries.


Furnace welded pipes: It can be used as water and gas pipelines, large-diameter straight seam welded pipes for high-pressure oil and gas transportation; spiral welded pipes for oil and gas transportation, pipe piles, bridge piers, etc.
