Piping Technology & Products, Inc. fabricated cryogenic pipe supports designed for a 14-inch pipe at a LNG plant in Algeria. The pipe operates below minus 50 degrees F, therefore the pipe supports were fabricated from three different materials in order to accommodate the low temperatures. The upper part, which clamps on to the pipe, was fabricated from a stainless steel plate that retains its strength at low temperatures. The middle section is a laminated phenolic block made from layers of wood impregnated under vacuum with a synthetic resin. A crossed orientation of the hard wood fibers is used to provide extra strength. The laminated phenolic block, which is a poor conductor of heat, was bolted to the bottom plate of the galvanized carbon steel.
Piping Technology & Products, Inc. specially designed and fabricated Big Ton Variable Springs for a chemical project in Canada. The supporting beams are 30″ in length with PTFE, 25% glass filled stainless steel slide plates. The Big Ton Springs were designed with six coil springs with external guides to prevent horizontal twisting and internal guides to withstand horizontal friction forces. These units were also designed for operating loads from 260,000 to 350,000 Newtons and hydro-test loads from 300,000 to 450,600 Newtons. A total of six units were painted with a special finish specified by the client.
Piping Technology & Products, Inc. custom designed and fabricated 1,728 rods and clevises for a heat recovery steam generation plant. The rods and clevises will be utilized to support various pipe loads throughout the piping system.

Piping Technology & Products, Inc. specially designed twelve Type-F variable spring hangers (4-160-F, 8-170-F, 8-180-F) for an oil refinery in Indiana. These variable spring hangers were custom designed to support a Hydro-Test load 4.5 to 5 times the design load, which ranged from 7,988 lb. to 13,075 lb. The spring rates of the variable spring hangers ranged from 500 lb./in. to 750 lb./in. with travels of 1.15″ to 2.82″, upward movement respectively. The locking devices for these springs were manufactured using basic materials (rods, hex nuts and heavy pipe wall) and a special pressure plate to accommodate the application design criteria requested by the client. The base plate designed for these F- Type cans were modified to accommodate the locking devices.
