ASTM A106 Seamless Steel Pipe
ASTM A106 Seamless Steel Pipe
Seamless steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell, without welding or
seam. It is suitable for bending and cutting. The advantage of seamless steel is the ability of withstanding higher pressure.
ASTM A106 is seamless steel pipe specification for high-temperature service. The pipe is commonly used in the construction of
power plant, boiler, firefighting pipeline and ship where the piping must transport fluids and gases in higher temperatures and
pressure levels.
·Certificate: ISO
·Standard: ASTM A106, Grade B
·Dimension: Sch40 / Sch80 as ASME B36.10M
·Application: Fire main pipe, fire pump pipe,
fire standpipe, fire sprinkler branch pipe
Note:
1. For NPS 1/2" to 3/4" pipe, the manufacturing method is cold drawn.
2. For NPS 1" to 1- 1/2" pipe, the manufacturing method is cold drawn or hot rolled process.
3. For NPS 2" to 3" pipe, the manufacturing method is hot rolled 6-5/8" PQF mill.
4. For NPS 4" to 12" pipe, the manufacturing method is hot rolled 10-3/4" PQF mill.

Note:
1. For fixed length, length tolerance is -0.0mm / +6.0mm, as ASTM A530.
2. The weight (mass) tolerance of unit pipe is -3.5% / +10%.
3. For pipe ≤ NPS 4", weight is measured as per bundle. For pipe > NPS 4", measured as per individual length.
