Application
Long distance pipeline
Crude oil often contains hard particles such as sand, which is easy to wear or scour the sealing surface and inner cavity of the valve. It is recommended to select a metal sealed ball valve. The sealing surface is coated by HVOF(high-velocity oxy/air fuel) or coating off nickel-based alloy process to increase the thickness and of the coating on the sealing surface and improve the wear resistance and scratch resistance
Offshore oil and gas platform
Offshore platforms not only face the external corrosion of the marine environment but also produce high content of H2S gas in the fluid, which may corrode the valves to a certain extent. We use materials conforming to NACE 0175 / ISO 15761 to manufacture the valves to eliminate the corrosion of H2S on the valves. The selected bolts and nuts are also sprayed with PTFE for anti-corrosion treatment
petrochemical industry
The petrochemical industry produces required chemicals through the processing of petroleum. Therefore, the working condition is characterized by high temperature, high pressure and strong corrosion. According to the composition content and temperature of the medium, the valve body materials and seals of different corrosion-resistant materials such as SS316, Inconel, Monel and Hastelloy are selected
Chemical industry
The chemical industry belongs to the continuous production type, and the production process requires safety, stability, and a long cycle, which is an important guarantee for energy conservation, stability, and high yield. Valves are widely used in low temperature, ultra-low temperature, high temperature, bellows, sulfur resistance, hydrogen resistance, wear resistance, low leakage, and other special conditions
liquified natural gas
Thermal power
In the thermal power generation industry, the medium of the pipeline is mainly high-temperature and high-pressure steam, which puts forward higher requirements for the sealing materials such as valve seat, gasket, and packing. In order to realize the normal sealing function under a high-temperature and high-pressure environment, sealing materials with good thermal stability should be selected
