| This
product is made of the special quality steel,
after being quenched and carried on the
carburizing chemical treatment on the inner
wall, the hardness degree of the flanged
bushings can reach 58-60 degrees, and the
serving life of pipeline can increase by
3-5 times, which can enable users save time
and costs, remove from the trouble of changing
the tube regularly, and enhance the production
efficiency. |
