A106 Seamless Pipes Manufacturers & Suppliers

  • A106 Seamless Pipes Available on Sale in Size Range of 1/2″ NB to 24″ NB
  • For pipe NPS 11⁄2 [DN 40] and under, it shall be permissible to furnish hot finished or cold drawn.
  • Unless otherwise specified, pipe NPS 2 [DN 50] and over shall be furnished hot finished. When agreed upon between the manufacturer and the purchaser, it is permissible to furnish cold-drawn pipe.
  • ASTM A106 Carbon Steel Pipe Application : ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

As one of the largest stockholder and supplier of A106 Grade B seamless pipes, Metallica has over 250 customers in India and overseas. The manufacturing specification, ASTM A106 generally includes 3 steel grades (Grade A, Grade B, Grade C), but ASTM A106 Grade B is most widely used grade.

ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) covers seamless carbon steel nominal wall pipe for high-temperature service. A106 pipes and tubes are widely suitable for bending, flanging and similar forming operations. It is the best choice grade for general and special piping applications.

A106 seamless pipes are used for conveying oil, steam, water, gas, air at low/medium/high pressure or temperature. Additionally these pipes are also used for fire protection systems, civil engineering, architecture and other structures, shipyard, oil field, and gas field.

Manufacturing & Testing Requirements for A106 Seamless Pipes

Heat TreatmentHot-finished pipe need not be heat treated. Cold-drawn pipe shall be heat treated after the final cold draw pass at a temperature of 1200 °F (650 °C) or higher.
Process
  • The steel shall be killed steel, with the primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining. If secondary melting, using electroslag remelting or vacuum-arc remelting is subsequently employed, the heat shall be defined as all of the ingots remelted from a single primary heat.
  • Steel cast in ingots or strand cast is permissible. When steels of different grades are sequentially strand cast, identifi- cation of the resultant transition material is required. The producer shall remove the transition material by any estab- lished procedure that positively separates the grades.
Surface TreatmentOil-dip, Varnish, Passivation, Phosphating, Shot Blasting
Hydrostatic TestingInspection test pressures produce a stress in the pipe wall equal to 60% of specified minimum yield strength (SMYS) at room temperature. Maximum Pressures are not to exceed 2500 psi for NPS3 and must stay under 2800 psi for the larger sizes. Pressure is maintained for not less than 5 seconds.
Nondestructive Electric TestThe full body of each pipe shall be tested with a nondestructive electric test in accordance with Practice E 213, E 309, or E 570.
Mechanical Tests Specified
  • Tensile Test — NPS 8 and larger — either transverse or longitudinal acceptable smaller than NPS 8 — weighed in lots.
  • Larger sizes — by length.
  • Flattening Test — NPS 2-1/2 and larger.
  • Bending Test (Cold) — NPS 2 and under.
