Cryogenic Sealing Solutions provides a powerful sealing mechanism for cryogenic materials such as cryogenic fluids. Sealing at cryogenic temperatures has its own unique set of challenges. JST Seals recently designed and shipped a very urgent LNG cryogenic valve seals for the overseas customer. Its completed working conditions are as follows: Fluid media LNG at temperature: minus 175°C Maximum temp...
In the oil and gas industry, the risk and consequence of unplanned downtime is greatest in extreme environments. JST has long been committed to the provision of sealing solutions for the exploration and production of oil and gas. Wellhead is a critical part of oil and gas infrastructure. Its sealing materials need to withstand pressures as high as 15 000 psi and temperatures of 149º C. From d...
Seal leakage of equipment in the oil, natural gas, and chemical industries would cause great loss of production, and it would cause severe environmental pollution, which has gradually increased users' requirements for safety sealing solutions. There are many factors that can cause seal leakage, the more common ones are as follows: 1. Installation problems: a. &nbs...
When it comes to sealing in harsh operating conditions, the Upstream Oil & Gas industry has some of the toughest applications out there. With fluids such as hydrocarbons and gases such as H2S, combined with pressures climbing well above 20k psi and temperatures drifting to 200° C and higher, reliability in sealing is an absolute must to mitigate against unproductive downtime. Adding steam and ...
JST develops and supplies downhole tool seals for the oil and gas industry. We have developed and improved PTFE, NBR, HNBR, FKM, peek and other materials. These materials have high pressure resistance and good sealing performance, and have passed the hydrogen sulfide immersion test and explosion-proof test. Generally speaking, sealing materials suitable for downhole harsh conditions are not easy t...
Guangzhou JST Seals offers downhole sealing solution and products. Bottom hole assembly (BHA) tools (such as impactors and jars) need to be sealed to protect the tool hydraulic system from the impact of abrasive drilling mud and cuttings in the hole. Measurement while drilling (MWD) tools sometimes need high-temperature sealing solutions. This field operation is expensive, If seal failed it would ...
T-seals have a double acting seal design that are available in both piston and rod profiles.Their design aid in preventing extrusion up to 5000 psi. They are also a more reliable options, as they help eliminate the rolling or spiraling associated with O-rings,provide better extrusion resistance than an O-ring or backup ring assembly, promote lubrication for reduced friction and wear. Our standard ...
Modified PTFE or TFM, is a high-density copolymerized material. It has low gas permeation and reduces cold flow. Often used in the medical field as an artificial blood vessel graft and in other applications where biocompatibility is required. TFM is also FDA and USP class VI suitable. TFM remains a largely unfamiliar material in the general PTFE machine parts and seal markets. At JST, we have...
