BOLTING

BOLTING air-powered torque wrenches, such as the NRP series, deliver fastening torque up to 2,212.7 ft-lb. For example, the NRP-30K model with a 1-inch square drive produces 2,212.7 ft-lb, while the NRP-15K and NRP-9K models offer 663.8 ft-lb and other intermediate values. These tools operate at 90 psi air pressure and are available with 3/4-inch or 1-inch drives. They are intended for high-torque fastening in industrial assembly, maintenance, and repair. The torque output is fixed by the tool's design, and selection depends on the required fastening torque and drive size. For precise torque control, hydraulic torque wrenches may be more appropriate.

BOLTING hydraulic flange spreaders, such as the FLS15-ST model, have a nominal capacity of 16.5 tons. They feature a 0.2-inch tip clearance for insertion into tight gaps and a 0.59-inch spread width. These spreaders are used to separate flanges in piping systems during maintenance or repair. The tool requires an external hydraulic pump to operate, which is not included. The compact design allows access to confined spaces, and the hydraulic operation provides controlled force for safe flange separation. When selecting a spreader, consider the required spread width and the available access gap. The FLS15-ST is part of the BOLTING line of hydraulic bolting tools.

BOLTING high-flow air-operated hydraulic pump units, such as the HPUTP150002K, have a maximum operating pressure of 21,750 psi. They feature a 2.5-gallon reservoir and a hand-operated, 2-position advance control. These pump units are designed for industrial tensioning and bolting applications requiring high flow and pressure. The air-operated design allows for use in environments where electric power may be unavailable or unsafe. The pump provides hydraulic power to torque wrenches, tensioners, or spreaders. When using this pump, ensure that all hydraulic connections are rated for the maximum pressure and that the system is properly bled. The 2.5-gallon reservoir capacity supports extended operation without frequent refilling.

BOLTING TWHC series hydraulic torque wrenches use square-drive sockets available in various SAE sizes. For example, the TWSIC219 socket has a 1-1/2 inch square drive, while the TWSIB-138 and TWSIB125 sockets have 1-inch square drives. These sockets are 6-point and designed for use with square-drive hydraulic torque wrenches. The TWHC series includes sockets to fit a range of fastener sizes. When selecting a socket, match the drive size to the wrench and the socket size to the fastener hex. The 6-point design provides full engagement on the fastener flats, reducing the risk of rounding. These sockets are part of the BOLTING bolting system and are intended for controlled torque applications.

BOLTING bolting tools are used in applications requiring controlled torque and reliable fastening. Typical uses include pipeline flange assembly and maintenance, where hydraulic torque wrenches and flange spreaders are employed. In power generation, they are used for turbine and pump bolting. Heavy equipment repair and industrial assembly often utilize air-powered torque wrenches for high-torque fastening. The tools are also found in oil and gas, chemical processing, and manufacturing plants. The selection of a specific tool depends on the torque requirement, access constraints, and power source available. For critical joints, hydraulic torque wrenches provide precise torque control, while air-powered wrenches offer speed and repeatability for less critical applications.
