Threaded Flange Plate
Threaded flanges, with internal and external thread meshing locking technology at its core, offer a zero-spark, detachable connection revolution for oil and gas, chemical and pharmaceutical, and fire protection systems through precision turning processes.
- Product Introduction
Products Description
Threaded flanges are used for weldless pipe connections, primarily in low- and medium-pressure applications. They offer advantages such as easy installation, reliable sealing, and low maintenance costs.
Products Advantages
No Welding Required
Utilizing a precision-machined thread structure (NPT/BSP standard), direct connection is possible without on-site welding.
Reliable Sealing
Thread tolerance controlled to ±0.01mm, with concentric machining of the sealing surface for more even pressure distribution.
Stable Pressure Bearing
Made with ASTM standard materials (A105/304/316) and manufactured according to ASME B16.5, ensuring stable compatibility with Class 150/300 piping pressures.
Corrosion Resistance
High Cr/Ni content and optional galvanizing or black paint finishes effectively reduce corrosion rates in humid and mildly corrosive environments, extending overall service life.
