We specialize in manufacturing high-quality industrial pipe fittings and precision-engineered pipe flange products for oil & gas, petrochemical, power generation, marine, water treatment, construction, and heavy industrial applications.
Our flange products are manufactured with strict dimensional tolerance, superior surface finish, and reliable mechanical strength to ensure leak-proof performance and long-term durability under high-pressure and high-temperature working conditions.
Available in multiple flange types including blind flange, slip on flange, threaded flange, and weld neck flange, our products are designed to meet international standards and customized engineering requirements.
Manufactured from premium carbon steel, stainless steel, alloy steel, and forged materials, our flanges comply with international specifications such as ASTM A182, ASME, ANSI, DIN, JIS, BS, and EN standards.
Each flange is processed using advanced CNC machining technology to ensure smooth sealing surfaces, precise dimensions, and excellent concentricity.
Our carbon steel flange and forged steel flanges provide outstanding resistance to pressure, wear, and harsh industrial environments.
Suitable for:
Available surface finish:
A blind flange is used to seal the end of piping systems or pressure vessel openings for maintenance, inspection, or future expansion. It provides reliable sealing performance under high pressure.
The slip on flange is easy to align and weld, making installation convenient and cost-effective for low-pressure applications.
A threaded flange connects pipes without welding, suitable for low-pressure systems or environments where welding is restricted.
The weld neck flange features a long tapered hub for superior strength and reduced stress concentration, ideal for high-pressure and high-temperature systems.
Popular material grades include:
ASTM A182, A105, F304, F304L, F316, F316L, Duplex Steel, and customized materials according to customer requirements.
