ASTM A106 Grade A Carbon Steel Seamless Pipes are Low Carbon Steel Pipes with 0.25 % carbon content with combination of 0.27-0.93 % manganese. These Pipes are also known as mild steel pipes and tubes.
ASTM A106 Grade A Pipes are low-cost Pipes easy to form and shape. These pipes are manufactured as per ASTM Specification and commercially referred as cs pipes or ms pipes. Low Carbon Steel Pipes are not as hard as hig carbon steel pipes, Though carburizing can increase its surface hardness.

All tubes are supplied with clean, square cut ends.Deburring and/or chamfering can be carried out on request.
Tubes are supplied normally without anti-corrosive treatment, but anti-corrosive treatment is available and is carried out on request.
ASTM A106 Grade A Carbon Steel Seamless Pipes are bundled as standard, with steel straps into hexagonal bundles with one end flush.Length sorting can be carried out on request. Tubes can also be bundled in multiples. Bundle weights are adjusted as requested by the customer. Each bundle contains tubes from a single cast/heat only.
ASTM A106 Grade A Carbon Steel Seamless Pipes is marked with tube type, heat number, steel grade and size. Information is repeated along the whole length of the tube. Other markings, such as stamping, can be made on request. Bundles are also labeled with a tag having info both alphanumeric and by bar code.
ASTM A106 Grade A Carbon Steel Seamless Pipes delivered direct from our mill is labeled in accordance with automotive standard, ie with both alphanumeric and bar code information. Customer specific data can be added on request.
WWP-404c is similar to ASTM A-53 except that Government inspection and continuous identification marking of electric weld and seamless is mandatory. It covers black and galvanized welded and seamless pipe for flanging, bending, and coiling and for use with fresh water, oil, steam, air, and gas on shore plus a limited number of shipboard uses. Sizes 1/8 inch through 24 inch.WWP-406c is a federal specification comparable to ASTM A-120 (withdrawn 1988). Mills can certify that A-120 pipe in a distributor-s stock meets all the requirements of WWP-406c.
C-200 covers black welded and seamless pipe intended for the conveyance of water in sizes 6 inch and larger. Specification prescribes hydrostatic test pressures for sizes of pipe covered. Tensile, flattening, and bending tests are required.
ASTM A106 Grade A Specification covers seamless carbon steel pipe for high-temperature service (Note 1) in NPS 1-8 to NPS 48 inclusive, with nominal (average) wall thickness as given in ANSI B36.10. A106 Pipes having other dimensions may be furnished provided such pipe complies with all other requirements of this specification. ASTM A106 Grade A Carbon Steel Seamless Pipes shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized.

In addition to the marking specified in Specification A 999/A 999M, the marking should have the length, an additional symbol -S-, if ASTM A106 Grade A Carbon Steel Seamless Pipes conforms to any of the Supplementary Requirements S1 to S6, the schedule number of the pipe is ordered to a schedule number viz. SCH 5,10,20,30,40,60,80,100,120,140,160,XS, XXS, STD, and the heat number of or manufacturer-s number by which the heat can be identified as per ASTM A106 Grade A.
Wall Thickness : the minimum wall thickness at any point or end on ASTM A106 pipes and tubes shall not be greater than 12.5% under the nominal thickness specified.
Inner Diameter: For pipe ordered in inside diameter, the inside diameter shall not vary more than ñ 1% from the required/specified inside diameter.
For ASTM A 106 Grade A Pipes ,When test reports are requested, in addition to the requirements of Specification A 530/A 530M, The manufacturer shall furnish to the purchaser a chemical analysis report for the elements required as per the chemical content of ASTM A 106 Grade A.
Pipes and Tubes manufactured as per ASTM A106 Grade A are certified with En 10204 Type 3.1/3.2. IBR,NACE,HIC,IGC,IMPACT are adhered as supplementary testing requirements.
A The minimum elongation in 2 in. (50.8 mm) shall be determined by the following equation: e = 625 000A0.2/U0.9
where:
e = minimum elongation in 2 in. (50.8 mm), %, rounded to the nearest 0.5%.
A = cross-sectional area of the tension test specimen, in.2, based on specified outside diameter or nominal specimen width and specified.
wall thickness rounded to the nearest 0.01 in.2 If the area thus calculated is greater than 0.75 in.2 shall be used, and U p specified tensile strength, psi.
A For each reduction of 0.01% below
mum, an increase of 0.06% manganese above the specified maximum will be permitted up to a maximum of 1.35%.
the specified carbon maxi- B The combination of Copper, Nickel, Chromium, Molybdenum & Vanadium Shall not exceed 1.00%
ASTM A 106 Grade A shall conform to a carbon equivalent (CE) of 0.50 maximum as determined by the following formula:
CE = %C + %Mn/6 + (%Cr + %Mo + %V)/5 + (%Ni + %Cu)/15 . A lower Carbon equivalent ration maximum may be agreed upon between the purchaser and the producer.
S5.3 The Carbon equivalent ration shall be reported on the MILL test report.
