Polished Rod

 

1.Sucker Rod for coal-bed gas production is an important component to connect surface pumping unit with down-hole pump in coal-bed gas rod production system.

2.We mainly produce 6 sorts and over 20 specifications of rods.

3.They are grade D rod, grade H ultra-strength rod, hollow rod, polished rod, pony rod and continuous carbon fiber rod.

4.Steel continuous sucker rod and continuous carbon fiber currently take the lead place at home.
