China Threaded Flange(TH) Factory

Threaded Flange(TH)

The product specification-SS Threaded Flange from China Manufacturer
Our SS threaded flanges are a type of pipe threaded flange designed for use in low-pressure piping systems where welding is not suitable. These threaded flange fittings are ideal for applications requiring easy assembly and disassembly, such as in chemical plants, refineries, and water treatment facilities.

Product Introduction

A typical flange connection consists of two flange discs, a sealing gasket, and multiple bolts or studs. The flanges are mounted at the ends of the pipes or equipment, with the gasket positioned between them to ensure tight sealing. The bolts are used to fasten the flanges together, applying uniform pressure on the gasket and maintaining the integrity of the connection under pressure or temperature variations.

Core Technology

Sealing Surface Design: Pipelines carrying highly corrosive media (e.g., sulfuric acid, hydrochloric acid) use tongue-and-groove flanges or metal seals to ensure leak-proof performance.
