KMT McCartney LDPE High Pressure Products
The KMT McCartney Hydraulic Stud Tensioner
The KMT McCartney Hydraulic Stud Tensioner provides a safe, easy and accurate method of pre-stressing large diameter stud bolts such as those used on Hyper Compressor cylinders and large block valves. Tensioners can be supplied for bolting sizes of 1 1/4” (31.8 mm) and larger, providing tensioning forces up to 275.000 lbs. (124.700 kg).
The Stud Tensioner Unit is self-contained and portable, needing only plant air of 100 PSIG (6.9 BarG). A simple push button controls the flow of plant air to a one or two stage diaphragm pump, which in turn, supplies hydraulic fluid to each of the tensioning heads.
Hydraulic pressures of up to 12.000 PSIG (827 BarG) is adequate to torque even the largest stud bolts. Custom “dial indicators” monitor stud stretch, insuring precise results. A small 1-gallon (3.8 l) hydraulic reservoir located along side the diaphragm pump provides for flooded suction. Each tensioning head is supplied with a hydraulic hose of adequate length for easy positioning. Large air and hydraulic pressure gauges provide easy monitoring of each tensioner cylinder while a hydraulic relief valve insures safe operation.
KMT McCartney PMP Reciprocating Test Pump
The KMT McCartney Model PMP air-driven test pump package is designed as a convenient and economical alternative to the stationary hydraulic pump. The unit is totally self contained and mounted on a heavy structural steel skid or a pneumatic wheeled cart for easy maneuvering.
Pneumatic piping is complete with filters, regulators, shutoff valves, and a safety relief valve. Customer supplied plant air with 1” pipe connection is all that is required for operation.
The 3-stage High-Pressure Intensifier is supplied with manifolded discharge piping complete with pressure gauge and isolation valves. A single 9/16” HP discharge connection is located at the panel.
HP Cylinders and Check Valves are constructed of VAR 4340 material to insure long and dependable service. A 24 gallon (91 liter) test fluid reservoir is mounted along side the intensifier to provide a constant positive flooded suction.
LDPE PMP Test Pumps are available with design pressures up to 100.000 PSIG (6.897 Bar).
