Product Description

Product Description

The ASTM A106 standard is synonymous with excellence in seamless carbon steel pipes. Renowned for its robustness and reliability, it is a staple in the industrial sector, thriving especially in high-temperature settings. This esteemed standard is categorized into three distinct grades: A, B, and C, each meticulously engineered with unique chemical compositions and mechanical attributes to cater to diverse application demands.
Versatile Applications of ASTM A106 Seamless Steel Pipes:
Boiler and Power Plant Excellence: Our ASTM A106 seamless steel pipes are indispensable in boilers and power plant operations, with A106 Gr. B pipes leading the charge. Their unmatched thermal conductivity and heat resistance assure seamless equipment functionality even under the most demanding conditions.
Petroleum, Natural Gas, and Beyond: The superior performance of SA-106Gr. C high-pressure boiler tubes (ASTM A106C) shines in high-temperature, high-pressure conditions across industries such as petroleum, natural gas, chemical, and power. These tubes are designed to withstand the harshest conditions, offering remarkable reliability.
Diverse Industrial Applications: From shipbuilding to aerospace, and automotive to military, ASTM A106 seamless steel pipes prove their versatility and reliability. Industries such as machinery manufacturing, energy, geology, and construction rely on these pipes for their diverse and demanding requirements.
Composition and Mechanical Mastery:
Carbon Content Precision: Grade A boasts a carbon content not exceeding 0.25%, Grade B ranges from 0.18-0.25%, and Grade C extends from 0.25-0.35%. As carbon content increases, so does strength, although excessive carbon can reduce toughness.
Manganese Mastery: Ranging between 0.29-1.06%, manganese plays a crucial role in refining grain size, fortifying ferrite, and enhancing both tensile and compressive strength.
Silicon Stability: With a silicon content carefully maintained around 0.10%, it serves as a key agent for deoxidation and purification of molten steel, ensuring superior steel quality.
Strength Specifications: Grade A's tensile strength starts at 330MPa with yield strength of 207MPa minimum. Grade B boosts these values to 415MPa and 240MPa, while Grade C offers an impressive 485MPa and 275MPa respectively, providing unmatched durability.
Elongation Efficiency: A vital elongation rate of over 30% ensures the pipes can absorb energy through deformation, mitigating impact forces and preventing brittle fractures.
