Why choose us:
1. All pipe fittings are strictly implemented in accordance with
the standards, accept any third-party inspection, and return
service.
2. Before leaving the factory, 100% dimensional inspection, 100%
spectral test, mechanical and mechanical performance test,
pickling, pickling process are mainly aimed at the removal of
surface grease and harmful substances, complete surface passivation
to prevent oxidation. Some suppliers have not implemented ( Because
the surface is not visible to the naked eye after sandblasting)
annealing and solid solution (heat treatment), many goods on the
market are not heat-treated. When the pipe fittings are in some
cold or hot environments, the seam will slowly crack if it is not
heat-treated. This process is invisible to the naked eye, surface
sanding (many relatively inexpensive processes on the market),
bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings
is heavier than that on the market, (Ensure the back arc thickness)
to avoid the parts of the same wall thickness that cannot be seen
by the naked eye after the processing The pressure is guaranteed,
because many suppliers choose the material to the maximum limit in
order to minimize the cost.
RFQ:
1. Are you a trading company or a manufacturer?
