3 Steel Material: Q235A, Q235B, Q345, ASTM A53/106, API 5L GR.A/B, A672 B60 CL22, L245 L290 X42 X46 X70 X80
4 Standards: API 5L, ASTM A672, SY/T5768-2006, GB/T3091-2008, GB/T9711-1
5 Applications: liquid delivery such as water, oil and gas, constructions, chemical plant, power plant, and offshore drill platform.
6 Packaging: in bundles with steel strips or in bulk as per loading requirements
7 Loading: mainly Tianjin port
8 Surface: anti-rust paintings, heat treatment, galvanizing, anti-corrosion treatment ( FBE, 3PE, 2PE)
9 Tests: factory in-house inspection, third party inspection ( SGS, BV, MOODY, CCIC),
Testing range: chemical composition, mechanical properties ( yield, tensile, elongation, impact) , flattening, bending, visual inspection, etc.
10 Mill Test Certificate: as per standard
11 Payment Terms: TT, LC
13 Mini Order: 10tons for carbon steel, 20tons for low alloy steel

B: ASTM A672 Standard 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.

Heat treatment should be considered according to the steel grades.
