Considering the range of polymeric compounds used in the various industries we serve, elastomeric materials can be among the most challenging, and sensitive materials to manufacture. To ensure materials are capable of surviving a range of performance and operating scenarios, from HPHT, to RGD, to ED, or supercritical gases, materials must be compounded and selected after evaluating a range of critical factors prior to the design process.
Our depth of experience allows us to produce materials with minimal batch variation and consistent quality. Our molding processes – compression, transfer, and injection – satisfy both low and high-volume production.
HEAT, CORROSION AND OTHER POTENTIAL THREATS
If materials are chosen improperly, bottom-hole temperatures (BHT) escalating to 400°F can pose an immediate threat to the integrity of seal materials, making the application susceptible to failure. Aggressive chemical environments such as hydrogen sulfide, paraffin inhibitors, acids, and bromides accelerate critical component corrosion. High levels of CO2, methane or other compressible fluids create rapid gas decompression (RGD), one of the leading causes of seal failure.
