Manufacturing Excellence

Sachiya Steel International Pvt. Ltd maintains only the highest standards when manufacturing ASTM A106 GR B pipes, using two primary processes for production: hot-finished and cold-drawn. In hot-finished production, pipes are heated to optimal temperatures before being carefully hand shaped before cold-drawing is used to achieve precise dimensions – our commitment to precision ensures each ASTM A106 GR B pipe surpasses rigorous quality benchmarks.      

At Sachiya Steel International, we take pride in our extensive inventory of ASTM A106 pipes, which cater to a wide range of needs and specifications.

  • Our pipe offerings encompass Grade B and Grade C, and they come in various sizes, starting from ¼” NPS and extending up to 24″ NPS. In response to our clients’ specific requirements, we’re also equipped to provide large-diameter pipes exceeding 24″ NPS.
  • The thickness of our pipes varies, ranging from SCH 20 to SCH XXS, conforming to ANSI B36.10 / ASME B36.10 standards. What sets us apart is our flexibility in accommodating non-standard thicknesses that may not be readily available within the specified dimensional standards.
  • When it comes to length, our pipes can be delivered in two options: single random lengths measuring 4 to 7 meters or double random lengths spanning 7 to 12 meters. Should our clients have precise length preferences, we’re more than willing to supply fixed-length pipes.
  • Quality is paramount to us, and we ensure the integrity of our pipes by offering Mill test certificates compliant with EN 10204 3.1 and 3.2. Additionally, our pipes meet the Indian boiler requirements through IBR Form III certification.
  • For clients with specific specifications, our pipes can be tailored to meet a range of additional requirements, including NACE MR0175, NACE MR0103, H2 Service, Wet H2S Service, AXN1, AXN2, AXN3, AXN4, UOP1, UOP2, NAC4, NAC6, and NAC7.
  • To accommodate various inspection preferences, we are open to working with any Third-party inspection agency chosen by our clients, ensuring that our products meet their unique standards and expectations.

Advantages of ASTM A106 GR B Pipes

Using ASTM A106 GR B pipes offers an array of advantages:

  • Temperature Resilience: With a tolerance for temperatures up to 750°F, these pipes excel in hot environments.
  • Corrosion Resistance: These pipes’ composition protects against corrosion in various settings.
  • Robust Strength: Their mechanical properties ensure resilience under high stress and pressure conditions.
  • Ease of Use: ASTM A106 GR B pipes are compatible with various welding and threading methods.

The ASTM A106 specification serves as the benchmark for carbon and alloy steel pipes. It outlines the specific requirements that such pipes must meet. Additionally, ASTM A530/A530M provides general prerequisites for specialized carbon and alloy steel pipes, ensuring they meet industry standards.

For assessing the quality of metal pipes and tubing, ASTM E213 prescribes the practice of ultrasonic examination. This method employs ultrasonic waves to detect any imperfections or irregularities within the material.

Eddy-current examination, as detailed in ASTM E309, is another crucial practice for assessing the integrity of steel tubular products. It uses magnetic saturation to identify potential defects or weaknesses in the material.

To further evaluate the quality of steel bars, billets, blooms, and forgings, ASTM E381 prescribes the macroetch testing method. This procedure involves etching the material’s surface to reveal any hidden flaws.

When dealing with ferromagnetic steel tubular products, ASTM E570 provides guidelines for conducting flux leakage examinations. This method helps in identifying issues within the material that might not be visible on the surface.

Finally, ASME B36.10M sets the dimensional standards for both seamless and welded pipes. These standards are crucial for ensuring that pipes fit and function as intended.

Hydrostatic Test

As part of our efforts to guarantee the quality of our pipes, we conduct hydrostatic tests on each pipe segment to verify there are no leaks through its walls. The hydro test exerts stress equivalent to 60% of its Specified Minimum Yield Strength (SMYS). For pipes up to 3″ NPS size, maximum allowable hydro test pressure should not exceed 2500 PSI while larger diameter pipes (above 3″) exceed this limit at 2800 PSI – this rigorous process ensures pipe integrity and safety.

ASTM A106 GRADE B / SA106 GR B PIPE WELDING PROCEDURE

SA106 GR B pipes

Carbon steel is a large category of steel that encompasses many varying chemical compositions. Each type of carbon steel requires different considerations when welding. For example if you choose Low carbon steel to weld which is typically the most readily welded steel in a room temperature environment. These low carbon steel suitable for welding include C1008, C1018, A36, A1011 and A500.

Medium carbon steel such as C1045 typically requires preheat and post-heat treatment to avoid weld cracking. High carbon steel is even more prone to weld cracking than the other two groups of carbon steel. Welding high carbon steel will most likely require very thorough preheating and post-heating processes to avoid this. It could also require special welding filler metals.

Standards referenced in the production of ASTM A106 pipes include the following ASTM standards:

a. ASTM A530/A530M: This specification outlines the common requirements for carbon and alloy pipes.
b. E213: The standard governing the Ultrasonic Examination test.
c. E309: The standard for the Eddy Current examination test.
d. E381: The standard detailing the Macroetch test plan for steel products like steel bars, steel billets, blooms, and forging steels.
e. E570: The standard outlining the test plan for the flux leakage test of ferromagnetic steel pipes and pipeline products.
f. Related ASME Standard:
g. ASME B 36.10M: The standard specification for nominal sizes of welded and seamless steel pipes.
h. Related Military standard:
i. MIL-STD-129: The standard addressing the markings of shipment and storage.
j. MIL-STD-163: The standard governing the storage and shipment of steel forging products.
k. Related federal standard:
l. Fed. Std. No. 123: The standard for marking and shipments for civil agencies.
m. Fed. Std. No. 183: The standard specification for continuous ID marking for steel products.
n. Surface standard:
o. SSPC-SP 6: The standard specifying surface preparation requirements.

Heat Treatment

Heat treatment requires considering the type of pipes being produced; those made through cold-drawn processes require normalized temperatures while hot finishing methods do not necessitate any additional processes for heat treatment.
