　　1. The hydraulic torque wrench adopts an aluminum-titanium alloy integral body, which is light in weight, small in size, large in strength and strong in toughness, ensuring durability, reliability and safety. Hydraulic torque wrenches are naturally aged for 2-3 years according to the national standard. Because this process takes too long, it is impossible for small-scale hydraulic torque wrench manufacturers to wait that long due to capital turnover. It is a factory producing hydraulic torque wrenches. It has strong economic strength and technical support. The huge production workshop and strict warehouse management system provide strong support for the natural aging of materials.

　　2. The aluminum-titanium alloy of the hydraulic torque wrench has good toughness, and the gear and drive shaft of the reaction arm can not break teeth or crack under the condition of high torque; although the reaction arm of aluminum alloy that has not undergone natural aging for 2-3 years has a certain strength , but the brittleness is large, the hardness is small, and it is prone to fracture and deformation at relatively weak connections.

　　3. The hydraulic torque wrench sealing system adopts imported sealing ring, which can withstand the work under the pressure of 70MPa for a long time, with slow aging and long service life; when the domestic rubber sealing ring works under the pressure of more than 60MPa, the performance is unstable and it is easy to be damaged. , resulting in oil leakage of the hydraulic torque wrench working head and short service life. As a result, the pressure cannot go up, and the torque output of the wrench is not enough.

　　4. The hydraulic torque wrench has introduced advanced CNC precision machining equipment, advanced machining technology and advanced management system to ensure the machining accuracy, make full use of the performance of CNC machine tools, improve machining efficiency, shorten machining time, and ensure that the product has sufficient in stock. However, small-scale hydraulic torque wrench manufacturers cannot mass-produce due to limited sales. They are basically workshop-type processing, and the processing technology and precision are not as good as those of the products, so the actual precision is greatly deteriorated.

　　5. It adopts pure imported high-pressure hose, and the safety factor is 4:1. The working pressure is 70MPa, and the burst pressure is 280MPa. The exterior is made of thermoplastic polyurethane material, the interior is designed with 4 layers, and the 2 layers are high-strength steel wires. The outer layer of the domestic high-pressure hose is wrapped in rubber, the safety factor is less than 2, and the inner layer is designed with 2 layers. The easy aging of rubber determines that the service life of the tubing is very short. If it is not replaced in time, it will easily cause safety hazards, such as working at 70Mpa. Perforation occurs in the state, and the consequences are unimaginable.

　　6. The material and sealing process of the quick connector are mature, the long-term work under the pressure of 70Mpa and the frequent disassembly and assembly process have little loss and strong durability.

　　7. It is a big brand, with good after-sales service, and after-sales service promises can be fulfilled. If the equipment is faulty, engineers can be dispatched to the site to solve the fault on time, without affecting the progress and tasks of equipment maintenance. Small-scale hydraulic torque wrenches are usually manufactured by their own factories due to their low prices, so they generally do not send special personnel to the site for service. After receiving the fault notification, they directly ask the customer to send the equipment back to the company, and the maintenance cycle is long.
