Abstract
A pipe fitting wireform which when threaded into a fitting allows a user to measure center-to-end or end-to-center of the fitting to determine the length of a pipe needed to connect a pair of pipe fittings in a pipe assembly. The fitting wireform is a coil with a free end bent laterally to form a tang. The fitting wireform having an outside diameter substantially equal to the nominal size of the pipe fitting with substantially the same number of turns per inch as the pipe fitting such that the pipe fitting wireform can be threaded into the pipe fitting.
Claims4
A pipe fitting wireform for use in determining a center-to-end or end-to-center pipe length for joining a pair of pipe fittings attached to a first and second pipe-to-be-joined, said pipe fitting wireform comprising a first circular coil of spring steel, said coil having an outside diameter substantially equal to the nominal size of one of said pipe fittings, said coil having substantially the same number of turns per inch as said pipe fitting such that the pipe fitting wireform can be threaded into the pipe fitting, said coil having a free end bent laterally to form a tang which passes through the center of the coil from one side to the other.
A method for determining a center-to-end or end-to-center pipe length for joining a pair of pipe fittings attached to a first and second pipe-to-be-joined comprising the steps of
- providing a pipe fitting wireform comprising a coil of spring steel, said coil having an outside diameter substantially equal to the nominal size of one of said pipe fittings, said coil having substantially the same number of turns per inch as said pipe fitting such that the pipe fitting wireform can be threaded into the pipe fitting, said coil having a free end bent laterally to form a tang which passes through the center of the coil from one side to the other,
- threading the pipe fitting wireform into said pipe fitting with the tang side last until the tang is flush with a face of the fitting,
- hooking a free end of a tape measure on the tang and measuring the distance between the tang and the center of the second fitting;
- adjusting the measured length for the make-up on the first fitting and the take-out on the second fitting.
A method for determining an center-to-end or end-to-center pipe length for joining a pair of pipe fittings attached to a first and second pipe-to-be-joined together comprising the steps of
- providing a pipe fitting wireform comprising a coil of spring steel, said coil having an outside diameter substantially equal to the nominal size of one of said pipe fittings, said coil having substantially the same number of turns per inch as said pipe fitting such that the pipe fitting wireform can be threaded into the pipe fitting, said coil having a free end bent laterally to form a tang which passes through the center of the coil from one side to the other,
- threading the pipe fitting wireform into the said pipe fitting with the tang side first to the extent of the make-up,
- hooking a free end of a tape measure on the tang and measuring the distance between the tang and the center of the second fitting;
- adjusting the measured length for the take-out on the second fitting.
