Oil field chains

Chains for the petroleum industry are key transmission and load-bearing components in core links such as petroleum exploration, exploitation, drilling and refining. They are mainly used in equipment such as oil drilling rigs, pumping units and oil production platforms, undertaking important functions such as power transmission, load bearing and material transportation. Due to their working environment mostly being extreme conditions of high temperature, high pressure, high corrosion and strong impact, compared with ordinary industrial chains, they have special requirements in material selection, structural design and manufacturing process, and are one of the core basic components to ensure the safe production and efficient operation of the petroleum industry.

Ke’ai Transmission Oilfield Roller Chains. To ensure the high reliability of these chains, the processing technology of parts is crucial. Compared with the production and manufacturing of other chains, it has the following characteristics:

1. Chain Plates: Wider waist dimension to improve the fatigue strength of chain plates;

2. Higher-grade alloy steel materials, with strict control of chemical composition to obtain consistent heat treatment results;

3. Steel ball hole extrusion after heat treatment, and the existence of pre-compressive stress achieves the best crack extension resistance;

4. The orifice of the interference-fit connecting chain plate is with a formed cone angle, which is convenient for customers to install without reducing its fatigue resistance;

5. For pin shafts, sleeves and rollers, the optimized carbonitriding micro-deformation treatment process ensures that the pin shafts maintain nearly perfect straightness;

6. Extrusion-molded sleeves and rollers have higher roundness, coaxiality and surface roughness;

7. Heat treatment equipment with accurate detection and control of furnace atmosphere;
