Special Treatment

● Surface sandblasting SA 2.5

A) Sand spraying inside and outside of the valve body B) The surface is detailed after sand spraying, and the paint has strong adhesion

c) If O2 ingredients in the medium> 23.5%, external sandblast treatment, no sandblasting is required inside

● Spray paint treatment after surface treatment

A) The surface temperature resistance can reach 450 ° C after the standard spray paint, and the higher temperature can be treated separately B. The two layers of paint and corrosion are 35 microns

● Valve board dense cover pile welding hard alloy

a) The cover of the valve board can be piled up and welded the alloy, Stellited GR.6,

b) Spray hard alloys such as tungsten carbide, and the hardness can reach HRC 60-7
