ASTM A106 / API 5L Gr.B Seamless Carbon Steel Pipe,1-1/4" SCH40
Quick Detail:
Description:
Carbon Steel Seamless Pipe:
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. Typically seamless carbon steel pipe fourteen inches and greater in diameter are rolled from shells which expand the diameter and reduce the wall until the desired dimensions are achieved. Sizes smaller than fourteen inches in diameter are typically stretch reduced whereby the diameter is gradually reduced and the wall relatively increased via a series of rolls. There is also a cold forming process for seamless pipe production, but such manufacturing processes are typically reserved for different alloys. Being that there is no seam, seamless carbon steel pipe is typically used in high pressure applications.

Features
The primary benefit of steel pipe is its strength. These pipes don’t crack under most impacts and can operate under high pressure. Under abnormal loads, steel will bend, rather than break.
Advantages | Disadvantages |
·High tensile strength ·High compressive strength .Range of corrosion protection systems ·Wide range of diameters and wall thickness ·Welded joints give continuity | ·Prone to external corrosion ·Electrolysis prone ·Jointing requires skilled welders ·Internal/external corrosion protection systems add to price ·Coatings and linings can get damaged during installation and by third parties |
