In contrast, dual-pin connections are employed in more demanding drilling environments, such as oil and gas exploration. These connections feature two pins that engage corresponding holes in the mating rod section, offering enhanced stability and reduced stress concentrations at the connection point. Dual-pin connections are ideal for high-torque situations and can significantly improve the overall performance of the drill string Dual-pin connections are ideal for high-torque situations and can significantly improve the overall performance of the drill string
- PTFE. PTFE excels at extreme operating temperatures from -80°C to 200 °C. It also boasts extremely good oil resistance and very good wear resistance.
Single - Lip seal gaskets are used in a wide range of applications due to their versatility and effectiveness. They can be found in automotive, aerospace, marine, and industrial machinery, as well as in household appliances and recreational vehicles. Some specific examples include sealing doors, windows, and hatches on boats and RVs, preventing water ingress in HVAC systems, and ensuring the proper functioning of hydraulic and pneumatic cylinders.
The edge of the metal is finely ground after seal manufacture in a centerless grinder to enable an interference fit in the oil seal housing. A slight chamfer on the outer diameter (OD) of the seal is desirable for easy assembly. The sealing lip is prepared by buffing, grinding or cutting away the rubber flash which occurs at the sealing edge. A fine sealing edge creates sufficient pressure on the shaft to minimise spring load, leading to lower friction whilst maintaining effective seal performance. The garter spring plays an important role in the efficiency of the oil seal. If its tension is too high, heat will be generated between the sealing lip and the shaft, and result in rapid wear of the lip. If too low, the spring will be ineffective and the sealing lip will be worn away leading to leakage of the fluid.
