Blast Joints A blast joint is shorter in length than standard tubular joint. Built with a heavy wall pipe it is incorporated in the production string to facilitate production across any perforated interval and zone. Blast Joints are manufactured to the following specs connections, lengths, weights and material grade. Crossover Blast Joints are heavy wall pin by box connectors used in tubing strings and are designed to minimize the effect of external erosive action caused by production fluids. Blast joints are located opposite the location of perforations in the production casing or just below the tubing hanger in sand frac designs. Crossover blast joints are manufactured from seamless mechanical tube in sizes ranging from 2 3/8” to 4 1/2” OD. Any length, grade of material, and threading is available at the customers request. Typical lengths are 10' and 20'. Both API and Premium threads are available.
Flow Couplings Crossover Flow Couplings are heavy wall box by box connectors used in tubing strings and are designed to minimize the effect of internal erosive action caused by production fluids. Flow couplings are located just above or below Landing Nipples, Safety Valves or Control Devices where turbulent flow problems are likely to occur. Crossover flow couplings are manufactured from seamless mechanical tube in sizes ranging from 2 3/8” to 4 1/2” OD. Any length, grade of material, and threading is available at the customers request. Typical lengths are 3' and 6'. Both API and Premium threads are available.
