Flame-retardant and explosion-proof pipeline flame arresters cover diameters from DN15 to DN300 and pressure ratings from PN1.6 to 4.0 MPa. Carbon steel and stainless steel shells paired with corrugated flame arrestor cores effectively prevent flame backfire, strengthening pipeline safety. Flanged hydraulic-pneumatic solenoid valves are available in sizes from DN25 to DN150 and pressure ratings from PN1.6 to 2.5 MPa. They feature corrosion-resistant valve bodies and specialized seals, support various power supply options, have an IP65 protection rating, and offer optional explosion-proof configurations for remote automated on/off control.

The national standard forged steel flanged gate valves are primarily available in small diameters (DN15–DN100), capable of withstanding pressures up to PN160MPa. The forged steel valve body, combined with a hard alloy sealing surface, offers excellent regulating and shut-off performance, making it suitable for high-temperature and high-pressure conditions. The natural gas filters are available in diameters (DN25–DN300) and pressures (PN1.6–4.0MPa), equipped with stainless steel filter elements, offering a filtration accuracy of 5–100μm. They feature integrated differential pressure monitoring and a drain structure, efficiently removing impurities and protecting downstream equipment such as flow meters and valves. All products in the series utilize flange connections, comply with national standards, and can be customized.
