Fracturing pump seals，also known as plunger pump packing or plunger packing seal, are mainly applied in fracturing trucks, mud pumps and cementing trucks for oil industry of harsh working conditions. The fracturing pump seals are combined with Top Adapter, Bottom Adapter and Pressure Rings. The number of the pressure rings is flexible, which allows the seal sealing at a wide range of pressures und...

Packer elements are rubber seals that operate under specific down-hole conditions and provide an elastomeric seal for either short-term or long-term completion. Packer elements are used between sections of oil and gas production tubing to prevent fluids and pressure from leaking through the joints. This protects the casing, production tubing, liner and wellbore wall above and below the p...

Valve seals precisely control the amount of oil entering the valve stem system, making them critical components in maintaining your engine’s compression levels. Having a valve stem seal that works correctly within any of your applications can save you time and money by eliminating the need for lengthy engine repairs and replacements. But how to install valve stem seals, please see below. Installat...

The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions. Benefits Very rob...

Pumpdown plugs separate cement from the displacement fluid during liner cementing operations. It released from the cementing manifold at the surface between the cement and the displacement fluid, wipes cement from the drillpipe and lands in the liner wiper plug. Applications Cementing operations during liner applications Wiping of the running string behind the cement with pumpdown plug Wiping of t...

Liner Wiper Plugs separates drilling fluid from cement during displacement. It can reverse in the pipe without breaking the lips. Products can be produced in a variety of compounds and are available in sizes ranging from 3 ½” to 9 5/8”. Materials: NBR, HNBR, XNBR, FKM Benefits Improves cement integrity at the liner toe by separating displacement fluids in the running string and liner Reduces drill...

Wiper seal, also known as the dust ring, is a type of hydraulic seal. Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system. This is usually accomplished by a seal having a wiper lip that substantially removes any dust, dirt or moisture from the cylinder rod e...

For the installation and assembly of step seal, first install the O-ring, and then install the wear ring of step seal. First heat the wear ring, put it on the shaft, and then cool it. When installing the wear ring, first press the wear ring inward along the diameter direction, then install the wear ring into the groove, and then smooth the deformation. For installation in northern winter, the wear...

Hammer Union Seal (Lip Seal) is relatively large elastomeric annular seal that is rectangular in cross section, and used in hammer union-style pipe connections to establish flow lines and prevent leakage. The hammer union seal is “actuated” when it is compressed between the coupling components when they are cinched up. Hammer Unions are usually used in the Oil & Gas Industry, in steel mills, c...

There are two sets of sealing rings (secondary sealing of oil casting head) at the bottom of conventional oil pipe head and casting head, which are used to seal the castings suspended at the top. At present, the commonly used seals are FS seal, S seal and P seal. The design of S and FS wellhead seals requires that they can withstand higher and higher pressure and temperature, and meet more stringe...
