BOYUE STEEL supply carbon steel seamless pipe to Sudan Petroleum , Iran Petroleum,
Peru Petroleum, Colombia Petroleum, ...Every year we export at least 150000 tons of carbon steel
seamless pipe to 42 countries .

We produce the highest quality steel products. Customers use our seamless standard and line steel pipe for a variety of critical applications, including the transmission of crude oil, natural gas and petroleum products, refining and process piping for the chemical and petro-chemical industries, structural members in the construction industry, slurry pipelines as well as water transmission line applications.
sage: Used for low pressure liquid delivery, such as water, gas, and oil.
ASTM A672 Standard Specification for Electric-Fusion-Welded Steel Pipe for
High Pressure Service at Moderate Temperature covers electrical-fusion-welded steel
pipe for high-pressure service at moderate temperature. Heat treatment may or may not be
required to attain the desired properties or to comply with applicable code requirements.
An analysis of each mill heat of plate material shall be made, also, an analysis of the
finished deposited weld material from each 500 ft or fraction thereof shall be made.
The mechanical test requirements includes one tension test specimen to represent each
lot of finished pipe, and one transverse-guided-weld-bend test (two specimens) to
represent each lot of finished pipe. Also, radiographic examination shall be made on the
full length of each weld.
1.1 This specification covers steel pipe: electric-fusion-welded with filler metal added,
fabricated from pressure-vessel quality plate of any of several analyses and strength levels
and suitable for high-pressure service at moderate temperatures. Heat treatment may or
may not be required to attain the desired properties or to comply with applicable code
requirements. Supplementary requirements are provided for use when additional testing or
examination is desired.
1.2 The specification nominally covers pipe 16 in. [400 mm] in outside diameter or larger
with wall thicknesses up to 3 in. [75 mm], inclusive. Pipe having other dimensions may be
furnished provided it complies with all other requirements of this specification.
1.3 Several grades and classes of pipe are provided.
1.3.1 Grade designates the type of plate used.
1.3.2 Class designates the type of heat treatment performed during manufacture of the
pipe, whether the weld is radiographically examined, and whether the pipe has been
pressure tested.
