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.

Pipe Marking:

a. The seamless steel pipe marking shall include the following: manufacturer's name or trademark, product standard number, steel grade, seamless steel pipe specification and traceability identification number (heat number).

b. The marking can be done by jet printing, stamping, rolling, printing, pasting or sticking labels.

c. The marking is required to be eye-catching and clear, with firm handwriting and not easy to fade.
