API 11B AISI 4130 1 1/4 " x 25Ft Alloy Steel Sucker Rods Pony Rod Polished Rod 4140
Product Description:
Zhongshi provide the sucker rod and polished rod with API SPEC 11B standard. They used in the oil industry to join together the surface and down hole components of a reciprocating piston pump installed in an oil well. The pump jack is the visible above-ground drive for the well pump, and is connected to the subsurface pump at the bottom of the well by a series of interconnected sucker rods.
Features of rod coupling:
1. Standard class T coupling: 5/8”; 3/4”; 7/8”; 1”; 1 1/8”.
2. Class T slim hole coupling: 5/8”SH; 3/4”SH; 7/8”SH; 1”SH; 1 1/8”SH.
3. Class SM coupling: 5/8”; 3/4”; 7/8”; 1”;
4. Sub-Coupling: 5/8”×3/4”; 3/4”×7/8”; 7/8”×1”; 1”×1 1/8”.
