Our ASME B36.10M Grade B carbon steel pipes are engineered for high-pressure and high-temperature industrial systems. With higher carbon content (0.3% max) than standard Grade A, these pipes deliver enhanced strength and durability for critical oil & gas, power plant, and process industry applications.

Key Features

 ASME B36.10M Compliant - Meets strict dimensional & material standards
 Grade B Carbon Steel - Higher tensile strength (≥60,000 psi) vs. Grade A
 Pressure-Temperature Optimized - Suitable for SCH 40 to SCH XXS heavy-wall services
 Seamless & Welded Options - ERW, SAW, or seamless manufacturing
 Corrosion-Resistant Coatings - Available with FBE, epoxy, or galvanized finishes

Technical Specifications

Parameter	Details
Standard	ASME B36.10M
Material Grade	ASTM A53/A106 Gr.B
Carbon Content	0.30% max (higher strength than Gr.A)
Size Range	1/8" - 48" (DN6 - DN1200)
