Servomax elastomer couplings feature a specially calibrated polyurethane insert, which is preloaded between precision machined driving jaws. The spacers are used for vibration damping, shock ...

Couplings chosen with application requirements in mind last longer, improve precision, and protect other system components from premature failure. • Engineers should choose couplings that compensate ...

Operators can avoid failure of couplings during hydraulic fracturing by using a design window when designing a casing string. Hydraulic fracturing treatments produce higher stress levels in couplings.

In recent years, environmentally-assisted cracking has caused failures of many Grade P110 couplings during fracturing operations, causing enormous economic loss to the oil and gas industry. Factors ...
