Brief:ASTM A106 Grade B Seamless Pipe is the most widely specified carbon steel pipe material for high-temperature service in refineries, petrochemical plants, and power generation facilities. Manufactured in accordance with ASTM A106/ASME SA106 standards, this seamless pipe is designed to operate reliably at temperatures up to approximately 427°C (800°F)
Brief:API 5L X52 PSL1 Line Pipe delivers reliable medium-strength performance for oil, gas, and water transmission applications. Available in seamless and welded formats with comprehensive quality assurance, it provides proven performance for pipeline infrastructure projects worldwide.
Brief:API 5CT K55 casing is a medium-strength steel pipe used in oil and gas well construction to maintain borehole stability, prevent formation collapse, and enable safe drilling fluid circulation. It shares the same chemical composition and yield strength as J55 but offers a higher minimum tensile strength, providing an extra safety margin against burst pressures.
Brief:API 5CT J55 casing is a grade of carbon steel pipe manufactured in accordance with the American Petroleum Institute Specification 5CT, specifically designed for use as casing in oil and gas wells. It is one of the most widely used casing grades for shallow to medium-depth wells, offering an optimal balance of mechanical properties, weldability, and cost-effectiveness.
Brief:ASTM A213 Grade T22 alloy steel tube is a high-performance chromium-molybdenum (2.25Cr–1Mo) steel tube designed for high-temperature and high-pressure service. It is widely used in power generation, petrochemical, and industrial boilers, where durability, creep resistance, and oxidation resistance are critical.
T22 offers a perfect balance of strength, thermal stability, and long-term service performance, making it suitable for superheaters, heat exchangers, and high-temperature piping systems. The seamless manufacturing process ensures a uniform microstructure, high integrity, and reliable mechanical properties.
Brief:The ASTM A335 Gr. P91 seamless pipe is an advanced ferritic alloy steel pipe specifically developed for high-temperature and ultra-high-pressure service. With a nominal composition of 9% chromium, 1% molybdenum, and controlled additions of vanadium and niobium, Grade P91 offers significantly improved creep strength and oxidation resistance compared to traditional Cr-Mo grades like P22 or P9.
Brief:ASTM A213 TP316L is a seamless austenitic stainless steel tube specifically designed for high-temperature and high-pressure service in boilers, superheaters, and heat exchangers. The "L" grade indicates low carbon content (≤0.035%), which provides superior resistance to intergranular corrosion after welding. The addition of molybdenum (2.0-3.0%) enhances corrosion resistance, particularly against chlorides and other aggressive media.
Brief:ASTM A790 Grade UNS S32760 duplex stainless steel pipe is a high-performance super duplex stainless steel pipe designed for extreme corrosion and high-strength applications. This grade features a balanced ferritic-austenitic microstructure (approximately 40–50% ferrite / 50–60% austenite) with added tungsten and copper, which further enhance its resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in aggressive environments. UNS S32760 is available in seamless and welded constructions, offering superior performance compared to standard duplex grades like S31803 and S32205.
Brief:API 5L X42 PSL2 welded line pipe is engineered for medium-pressure oil, gas, and water transmission lines where enhanced toughness, stricter chemical limits, and traceability are required. Manufactured to API Specification 5L PSL2, this pipe outperforms PSL1 in fracture resistance, weldability, and low-temperature performance — ideal for onshore and offshore projects with demanding service conditions.
