Material Overview & Specifications

Tatvam Overseas Inc is a premier stockist, stock distributor, and bulk exporter of high-integrity Carbon Steel Seamless Pipes conforming to ASTM A106 Grade B, ASTM A53 Grade B, and API 5L Grade B based in Mumbai, India. Backed by extensive warehouse facilities in Kalbadevi and Girgaon, we maintain ready stock of over 400 metric tons of seamless carbon steel pipes serving oil refineries, gas transmission pipelines, firefighting lines, and heavy engineering projects.

ASTM A106 Grade B is the benchmark specification for seamless carbon steel pipe engineered for high-temperature and high-pressure service in power stations, oil refining units, and industrial steam boilers. API 5L Grade B (PSL-1 & PSL-2) governs steel pipe suitable for the transportation of oil, gas, and hydrocarbon slurries in pipeline transportation systems. Our pipes feature dual certification (ASTM A106 Gr B / API 5L Gr B) to afford maximum versatility across structural and process piping designs.

Our comprehensive size range extends from 1/2 inch NB through 24 inches NB in seamless execution, across schedules ranging from standard weight (STD / SCH 40) up to extra heavy (XS / SCH 80), Schedule 160, and double extra strong (XXS). Pipes are supplied with black rust-preventative varnish, beveled ends for butt-welding, and heavy plastic end protectors.

Quality assurance at Tatvam Overseas Inc encompasses rigorous third-party inspection compliance, hydrostatic pressure testing up to 3000 PSI, non-destructive ultrasonic and eddy current examination, and full heat traceability. Every pipe length is continuously stenciled and delivered with authentic EN 10204 3.1 Mill Test Certificates and optional NACE MR0175 / ISO 15156 sour service compliance.

Frequently Asked Questions

What is the difference between ASTM A106 Grade B and ASTM A53 Grade B? ↓
ASTM A106 covers seamless pipe exclusively, intended for high-temperature service. ASTM A53 covers both seamless and welded pipe for general structural, air, steam, and water piping applications. Most of our stock is dual-certified A106/A53/API 5L.
What is the difference between API 5L PSL 1 and PSL 2? ↓
API 5L PSL 2 specifies more stringent technical requirements including mandatory fracture toughness (Charpy V-Notch) testing, mandatory chemical composition limits, and stricter non-destructive inspection compared to PSL 1.
Can you supply pipes cut to custom lengths? ↓
Yes, our warehouse facility is equipped with automated band saws capable of cutting carbon steel pipes up to 24 inches in diameter to exact project cut lengths.
Are these pipes certified for sour service applications? ↓
Yes, we stock NACE MR0175 / ISO 15156 compliant pipes tested for Hydrogen Induced Cracking (HIC) and Sulfide Stress Corrosion Cracking (SSCC) for sour gas and oil refineries.
What is your Minimum Order Quantity for carbon steel pipes? ↓
Our standard warehouse MOQ is 500 kg or 1 standard bundle. Containerized export orders are stuffed and dispatched within 3 to 5 business days.
