High Quality API 5L ASTM A106 Sch40 Sch80 Sch160 St52 Q345b St37 A106c 210c Seamless Carbon Steel Pipe
Short Description:
The ASTM A210 standard covers seamless medium carbon steel boiler tubes and superheater tubes. Seamless medium carbon steel pipes for boiler tubes and boiler flue pipes.
“Quality very first, Honesty as base, Sincere assistance and mutual profit” is our idea, in an effort to create consistently and pursue the excellence for High Quality API 5L ASTM A106 Sch40 Sch80 Sch160 St52 Q345b St37 A106c 210c Seamless Carbon Steel Pipe, We will wholeheartedly welcome all purchasers from the industry the two at home and abroad to cooperate hand in hand, and produce a bright foreseeable future jointly.
“Quality very first, Honesty as base, Sincere assistance and mutual profit” is our idea, in an effort to create consistently and pursue the excellence for China Carbon Steel Pipe and Carbon Pipe, Now the competition in this field is very fierce; but we will still offer best quality, reasonable price and most considerate service in an endeavor to achieve win-win goal. “Change for the better!” is our slogan, which means “A better world is before us, so let’s enjoy it!” Change for the better! Are you ready?
Delivery Condition
Annealed, Normalized, Normalized and Tempered.
Surface Treatment
Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting.
Application
For high, middle, low pressure boiler and pressure purpose.
Length: 5800mm; 6000mm; 6096mm; 7315mm; 11800mm; and so on.

This specification 2 covers minimum-wall-thickness, Seamless Medium-Carbon Steel, boiler tubes and boiler boiler, “covers”, “1″.
Note 1 – This type is not suitable for safe ending by forge welding.
The tubing sizes and thicknesses usually furnished to this specification are 1/2 in. to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to in. 0.500 [0.9 to 12.7 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
Mechanical property requirements do not apply to tubing smaller than 1/8 in.
The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents therefore, each system must; be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of specified this specification is in the order.
Orders for material under this specification should include the following, as required, to describe the desired material adequately:
Quantity (feet, metres, or number of lengths), Name of material (seamless tubes), Grade, Manufacture (hot-finished or cold-finished), Size (outside diameter and minimum wall thickness), Length (specific or random), Optional requirements (Sections 7 and 10), Test report required, (see Certification Section of Specification A 450/A 450M), Specification designation, Special requirements.
