Xi 'An QinSteel Trading Co., Ltd specializes in manufacturing ASME B16.11-compliant Forged Steel Weldolets, delivering robust solutions for oil and gas pipeline operators worldwide. With GMP-certified facilities and API 6A compliance, we ensure precision-forged components that withstand extreme pressures up to 9,000 PSI. Whether you need bulk orders for pipeline expansions or urgent deliveries to remote drilling sites, our 15,000+ ready-to-ship units and custom engineering support keep your projects on track.
The products are critical for creating leak-proof branch connections in high-pressure oil and gas pipelines. Engineered to meet MSS SP-97 and ASME B16.11 standards, our weldolets feature precision-forged construction for enhanced mechanical strength and fatigue resistance. Available in carbon steel (A105), low-temperature alloys (A350 LF2), and corrosion-resistant stainless steels (F304/F316), they’re ideal for offshore rigs, refineries, and petrochemical plants.
