Abstract
An apparatus is disclosed that forms a piping thread form of four threads per inch pipe (TPI). The thread form is configured to have a load flank, a load flank angle, a stab flank, a stab flank angle, a crest, and a root. Hydrostatic pressure tests using the 4-round thread form at pressures of 4,500 psi and greater resulted in failures due to thread leaks. Tensile tests using the 4-round thread form at loads of 187,400 lbs. and greater resulted in shearing at forces of 3,535 psi and greater.
