As a trusted manufacturer of ASME B16.20 gaskets, we specialize in high-performance sealing solutions for oil, gas, and petrochemical industries. With over XX years of expertise, our gaskets are engineered to meet strict international standards, ensuring leak-free performance in extreme temperatures (-200°C to +800°C) and pressures (up to Class 2500). Whether you need spiral-wound, ring joint, or custom-designed gaskets, our scalable production and global logistics guarantee timely delivery.
The products are critical for maintaining flange integrity in high-pressure systems. Our products combine precision engineering with materials like stainless steel, carbon steel, and advanced fillers (graphite, PTFE) to deliver unmatched corrosion resistance and durability. Available in sizes from ½” to 60” (DN 15–1500), these gaskets are ideal for pipelines, refineries, and power plants.
