Turbine Repair Wrench Series: High-Strength Tools for Power Generation Maintenance

Product Overview

During turbine installation, commissioning, and routine maintenance, high-precision, high-strength manual tools are essential for ensuring repair quality and operational safety. This series of wrenches is specifically designed for the high-temperature, high-pressure, and space-constrained environments of a turbine.

The tools are fabricated from high-quality alloy steel, reinforced with heat treatment, and finished with a rust-proof surface process. This manufacturing ensures superior high strength, wear resistance, impact resistance, and slip resistance for reliable assembly, disassembly, and tightening of nuts on key components such as the cylinder body, valves, and couplings.

Product Categories and Main Uses

Box Wrench (Socket Wrench):
  • Description: Features an enclosed, cylindrical structure.
  • Main Use: Ideal for deep holes or confined spaces. Typically used for disassembling nuts and countersunk bolts on the horizontal split flange of high and medium-pressure cylinders.
Hex Key Wrench (Allen Wrench):
  • Description: Available in various L- or T-shaped designs for flexible operation.
  • Main Use: Used for tightening hexagon socket head screws on components like control valves and instrument joints.
Wrench Adapter (Socket Adapter):
  • Description: Connects standard sockets to electric or pneumatic drive tools.
  • Main Use: Used with ratchet wrenches and torque wrenches for quick assembly and disassembly, significantly increasing efficiency.
Slotted Striking Wrench / Ring Striking Wrench:
  • Description: Features a thickened striking end designed for use with a sledgehammer.
  • Main Use: Used for the initial pre-tightening and final loosening of large-diameter nuts, such as main cylinder bolts, requiring significant force.
Slotted Wrench / Slotted Nut Wrench:
  • Description: Specifically designed to engage slotted nuts, preventing slippage.
  • Main Use: Typically used on anti-loosening structures like bearing caps and end cover locknuts where precision and non-slip action are required.
Box Wrench (Ring Wrench - Closed End):
  • Description: Features an enclosed ring head design.
  • Main Use: Ensures even force distribution around the nut, preventing damage to the nut's corners. Suitable for tightening standard hex bolts and for use in confined spaces.
Slotted Wrench (Open-End with Slot):
  • Description: U-shaped open-end design with a slot specifically for engaging groove structures.
  • Main Use: Used for special connectors and locking nuts for locating pins where a standard open-end or box wrench cannot fit the geometry.
Striking Wrench (Heavy-duty Open-End or Ring):
  • Description: Forged as a single piece with strong impact resistance.
  • Main Use: Used for disassembling and assembling high pre-tensioned bolts on cylinder flange connections, where extreme force is necessary.
Six-Claw Wrench (Six-Point Socket/Box Wrench):
  • Description: Features a six-point engagement design to significantly reduce the risk of stripping or slipping.
  • Main Use: Used for the precision assembly and disassembly of valuable and delicate nuts, ensuring the integrity of the fastener corners.
