The difference between Seamless Steel Pipe and Welded Steel Pipe

 

1. Appearance difference

Welded steel pipe surface quality is much better than seamless steel pipe.

 

2. Molding process differences

Seamless steel pipe can be formed one time in the rolling process.


Welded steel pipe is manufacturing with steel strip or steel plate, through bending and different welding processes.

 

3. Performance and Usage

Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries.


Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance.

 

4. Available Sizes differences

For most of seamless steel pipe manufacturers in China, they produce original seamless pipe sizes maximum OD in 20 inch, 508 mm, because of the equipment limits.


On the contrary, welded steel pipe don’t have these limitations, sizes available from 1-1/2 inch 48.3mm to 100 inch 2540 mm.

 

5. Cost and prices

Usually the seamless steel pipe cost is higher than welded steel pipes, because the raw material, manufacturing equipment and processes. But sometimes by the market pressure, welded pipe is more expensive.

 

We can provide both seamless steel pipes and welded steel pipes, they are widely used in low and medium pressure boilers, petroleum casing pipes, ships, fluid conveyance, petroleum cracking, chemical fertilizer equipment, structures, and hollow pumping rods. We can produce pipes according to the standards such as GB, ASTM, API 5L, API 5CT, DIN and JIS.
