Well completion is the process of making a well ready for production after drilling. As in well drilling, seals used in well completion have to cope with the increasingly harsher conditions of deeper wells and diverse geographical areas, from the heat of Africa to the cold of Canada, Norway or Russia, with storage conditions as low as to -60℃. The system pressure can vary from 345 bar to 2070 bar,...
Well drilling is the process of extracting oil and natural gas from the ground (both onshore and offshore). As the well becomes deeper, the seals used in drilling must adapt to increasingly harsh environments. System pressures up to 2,070 bar (30,000PSI)and operating temperature extremes between -50℃(-58℉)and 220℃(428℉) are common. At the same time, seals used in drilling applications must have ex...
Whether it is on onshore oil wells, offshore drilling platforms, or subsea oil wells, it is necessary to avoid blowouts at all costs - or uncontrolled release of natural gas and/or crude oil from excavation sites. JST provides high-quality industrial rubber products for the oil field industry, such as rubber blowout preventer seals. With the help of the blowout preventer seal, the well can be safe...
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...
