Lockdown screw seals have been widely used in geothermal applications as they provide superior performance over traditional metal pressure seals. These seals are designed to handle high pressure and high temperature conditions, making them an ideal choice for geothermal applications. Lockdown screw seals consist of HNBR (Hydrogenated Nitrile Butadiene Rubber) packing with stainless steel caps that...

PTFE seal designs were developed to incorporate energizing elements such as O-Rings and metallic springs. These energizers ensure the PTFE seal is always in contact with the sealing surface. JST utilizes three different types springs to internally energize PTFE and other polymer seals, each with its own advantages. Below, we will discuss in details for some of the advantages of cantilever V-spring...

SLS sealing packing is a high-quality stem packing primarily used in FLS and FLS-R style gate valves. This seal is spring energized and is applied to the top of the valve bonnet around the valve stem.  On the hydraulic valve, additional SLS packing is used at the bottom of the valve with the lower balance valve stem. Materials and Components The high-quality materials used by Heshka Oil in SL...

Wear strips are suitable for guiding pistons and piston rods of hydraulic cylinders and pneumatic cylinders with supporting and guiding functions. We can provide double-sided embossed wear strips with a thickness equal to or greater than 2mm. The embossed structure facilitates the formation of lubricating micro-pits, improves micro-lubrication and protects the sealing system. Polyester resin fabri...

A water pump seal is a mechanical component that helps to contain the liquid inside a pump and prevent it from leaking. The seal is usually located between the pump's rotating shaft and the pump housing. The purpose of a water pump seal is to provide a barrier between the liquid being pumped and the environment outside the pump, thus preventing leaks and contamination of the liquid. There are seve...

Cementing wiper is one of the indispensable auxiliary tools for downhole operation. Its main use is to remove the mud from the outer wall of the drill pipe, to keep the drill pipe and the drill floor environment clean, and make it easy to check the scars on the scraped drill string, which can help us lower the risk of potential accidents. During the downhole work, there may be cement blocks, cemen...

FKM – Fluoroelastomers FKM is a fluorocarbon rubber, commonly referred to as fluorine rubber, VITON and FPM. They provide additional heat and chemical resistance. FFKMs are perfluororelastomer compounds containing an even higher amount of fluorine than FKM fluoroelastomers. They have improved resistance to high temperatures and chemicals and even withstand environments where Oxygen-Plasma are pres...

Grooves and Glands The physical space occupied by the seal is usually referred to as a groove, but it can also be referred to as a gland. In most cases, it’s a rectangular groove cut into the hardware whether it be on a piston, in the housing for a rod, or in the face of two mating surfaces. Compared to O Ring and elastomer seals, PTFE and polymer seals are critically dependent on hardware conditi...
