Wear-resistant tube series |
  |
| 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. |
