Class 150 Low Pressure Blind Flanges
Designed for low-pressure applications (100-299 psi), our Premium 150 Series Sealing Flanges ensure a secure connection for piping systems and pressure vessels. These flanges, also known as blanking flanges, are essential for sealing off system ends or openings to facilitate pressure testing of gases or liquids. Available with raised, flat, or RTJ (ring-type joint) faces, they cater to various sealing requirements. Constructed from Type 304 stainless steel, these flanges offer excellent resistance to corrosion from water, heat, saltwater, acids, and minerals. For environments demanding superior durability, the Type 316 stainless steel option, enriched with nickel and molybdenum, provides enhanced corrosion resistance.

Class 150 Low Pressure Butt Weld Flanges
Designed for low-pressure systems (100-299 psi), our Premium Class 150 Welded Neck Flanges ensure a secure and efficient connection between pipes and fittings. These flanges, known for their welded neck design, seamlessly transfer stress from the flange to the pipe, enhancing system integrity. With an inside diameter that perfectly matches the pipe, they facilitate an unobstructed flow of gases or liquids. Featuring a RTJ (ring-type joint) face, these flanges guarantee a smooth, flush connection. Crafted from Type 304 stainless steel, they offer excellent resistance to corrosion from water, heat, and various chemicals. For environments demanding superior durability, Type 316 stainless steel options are available, boasting enhanced nickel content and molybdenum for unmatched corrosion resistance.

Class 300 Medium Pressure Blind Flanges
Our Premium 300 Series Medium-Pressure Sealing Flanges are designed for robust connectivity in medium-pressure (300-999 psi) piping systems. These flanges, often referred to as sealing flanges, provide a secure closure for piping or pressure vessel openings, facilitating safe and efficient flow testing of gases or liquids. Available with raised, flat, or RTJ (ring-type joint) faces, they ensure a perfect seal. Crafted from Type 304 stainless steel, known for its chromium-nickel composition, these flanges offer superior resistance against corrosion from water, heat, saltwater, acids, and various minerals. For environments demanding even higher resistance, our Type 316 stainless steel option includes added molybdenum, enhancing durability against harsh conditions.
