API 11B Sucker rod,polish rod,sucker rod centralizer,sucker rod coupling for oil pumping out

Polish rod is a kind of special sucker rod connected with sucker rod and beam hanger. It is at the top of sucker rod, need to bear the most strength, so with bigger diameter and higher steel grade than sucker rod, and the surface is very smooth.Sucker Rod Nominal Value Φ16(5/8")Φ19(3/4")Φ22(7/8")Φ25(1")Φ29(11/8").

Orchid Energy Co Sucker rod is an important part of a sucker rod pumping equipment. Sucker Rod connect with coupling to be a rod string, and up through polished rod connection on the pumping unit or PCP motor, down connection on the pump piston or PCP, its role is to ground the reciprocating movement of the pumping unit horsehead suspension point is passed to the downhole pump or pass the rotation of the PCP motor torque to downhole PCP. Sucker rods are divided into grade of C, K, D, KD, HL, HY according to mechanical properties.

Orchid Energy Co Sucker rod centralizer is a kind of downhole tools which is pumping well anti-abrasion, it is especially suitable for pumping well and directional well which above of sucker rod middle point, under the middle point of sucker rod , the rod body with nylon centralizer is works better. The centralizer is made of high strength wear-resistant material, and touched with the tubing to reduce the abrasion to achieve the purpose of anti-abrasion.

Sucker rod coupling, sub-coupling and spray coupling which are designed according to API Spec 11 B standards using the high quality carbon steel or alloy steel (the equivalent of AISI 1045 and AISI 4135) and plating metal is a kind of surface hardening technology, is the nickel, chromium, boron and silicon powder coated on the substrate metal and fused with the laser processing, Coupling type: Class T (full size and slim hole ) ,Class SM (full size and slim hole ).
