Manufacturing Process:
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.
Is seamless pipe stronger than welded pipe?
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.

Carbon steel welded pipe and tube are used in high-pressure conditions. They are highly resistant to shock and vibration, making them ideal to transport fluids. Carbon steel pipes are widely used in a number of industries, such as transporting water and sewage, oil and gas industries, boiler and condenser tubes, high-pressure applications, and chemical processing.
- Transporting water and sewage
- Oil and gas industries
- Boiler and condenser tubes
- High-pressure applications
- Chemical processing
