Brief: Socket Welding Flange is a forged hub flange. The pipe is inserted into the flange socket and fillet welded on the outside. It features compact structure, reliable sealing and excellent pressure resistance. It is commonly used for small-bore pipelines of oil, gas, steam and chemical media. Sealing faces including RF, FF and RTJ are available.
Brief: Loose Flange consists of loose flange ring and stub end. The flange ring can rotate freely for easy bolt hole alignment. It helps save high-cost alloy materials and is suitable for corrosive medium. Widely applied in stainless steel and titanium piping systems.
Brief: Long Welding Neck Flange is an integrated forged flange with extended tapered hub. The longer hub optimizes stress distribution and reduces welding joints. It fits vessel nozzles, high-temperature, high-pressure and critical process pipelines. Hub length can be customized as drawings.
Brief: This pressure relief valve is a hydraulic self-operated control valve for pipeline protection, used in water supply, drainage and fire-fighting systems. It automatically releases excess pressure to avoid pipe bursts, or maintains stable upstream pressure. Composed of main valve, pilot valve and gauges, it runs on fluid pressure without external power. It features sensitive response, easy installation and low maintenance. Widely applied in high-rise buildings, water plants and industrial water systems.
Brief: The High-Speed Combination Air Valve is designed for water supply, fire water, pump station and pipeline systems. It can quickly discharge large volumes of air during pipeline filling, admit air during pipeline draining or vacuum conditions, and release accumulated air during normal operation. This valve helps protect the pipeline system, improve flow efficiency and reduce pressure fluctuation.
Brief: air valve series includes flanged combination air valves, double-orifice air valves, easy-maintenance air valves, large-orifice air and vacuum valves and threaded automatic air release valves. Different designs are available for different pipeline sizes, pressure ratings and working conditions.

Brief: This 1" UL/FM approved valve is specifically designed for use in wet pipe fire sprinkler systems. Manufactured in accordance with UL 2573 and FM 1344 standards, the valve provides reliable pressure control, excellent leak tightness, and stable venting performance under rated working conditions.
With NPT threaded connections, the valve ensures easy installation and strong compatibility with international fire protection piping systems. Its robust construction allows it to perform safely under continuous operating pressure and temperature ranges commonly found in fire protection applications.
