Specifications
- Spray Metal coupling
- •Basic material: Steel alloy 40Cr ( AISI 5140, HRA 56-62);
- •API SPEC 11B specification manufacture;
- •Inside diameter: 35.38mm(error bound: 0~+0.25mm);
- •Outside diameter: 55.6mm(error bound: -0.25~+0.13mm).
- •Casted alloy layer process on the surface has the function of wear-proof, corrosion-resisting and reducing the friction, protect both the coupling and the rods
Features
- It is made of good quality steel
- The deflection-proof and abrasion-proof sucker rod joint is processed with some special technology, coated a layer of abrasion-proof, wear-proof and lessening friction coat. This kind of joint can protect not only itself but also the rod, preventing and slowing down the wear.
Certificate
- API and ISO9001:2000
