Pipelines and valves and other equipment play an important
role in modern coal chemical plants. The harsh transportation conditions of the
coal chemical industry put a large toll on the pipelines and valves requiring
frequent and serious wear causing failure problems. Therefore, the requirements
for corrosion resistance and wear resistance pipeline valves are very high.
High-speed erosion wear mainly occurs in the spool of the regulating valve, the
plunger valve, and the ball component of the ball valve. The surface hardening
method and material selection of wear-resistant valves directly affect the
performance and working life of the valve. Seed provides high-end wear-resistant
materials and skilled valve surface hardening technologies such as: special
powder metallurgy, supersonic flame spraying, vacuum fusion, flame re-melting
process, laser cladding and more. Seed provides solutions for the severe
working conditions of the coal chemical industry.
