Digital torque wrench should pay attention to those problems when using
Digital torque wrench should pay attention to those problems in use, digital torque wrenches are not unfamiliar to everyone, its main role is to tighten and detect bolts, a wide range of applications, reinforcement torque, only need to set the required value can be The operation is comparatively simple, so we all know what problems should be paid attention to in the use of digital torque wrenches in order to reduce errors. Users who do not understand quickly have a look.
Digital torque wrench in use should pay attention to the problem:
1. When using the digital torque wrench, firstly select the moderate range according to the requirements of the measurement item. The measured torque value can not be less than 20% of the digital torque wrench in use. The too large range should not be used for small Torque item reinforcement, small-scale digital torque wrench can not use over-range.
2. When using a digital torque wrench, first connect the force pawl to an auxiliary accessory (such as a sleeve, various types of mouthpieces) to ensure that the connection is no problem. Before reinforcing the torsion, set the required reinforcement value, lock the locking device, and then adjust the direction change button to the direction of the force.
3. During the measurement, the hand must grasp the effective range of the handle, and slowly increase the force along the direction perpendicular to the body until the sound is heard after reaching the set value. During the exertion of force, in accordance with the norms governing instrument regulations in the country, the verticality deviation should not exceed 10 degrees. The vertical deviation in the horizontal direction should not exceed 3 degrees. In the course of use, the controlling personnel should ensure that the range of up, down, left and right exertion does not exceed 15 degrees.
4. In order to prevent the measurement result from being affected by horizontal and vertical deviations, a vertical downward stabilizing force should be applied to the gripping end of the grip.
Digital torque wrenches are an indispensable part of our lives. We must fully understand its characteristics in order to maximize its role!

Steel Coupling
Steel coupling is a piece of short pipe that is used to connect one pipe with another pipe, scope of application is also more widely, like agriculture, industry, construction and so on. There are socket welding couplings and threaded couplings, they are all High Pressure Forged Fittings. Pressure shall be CLASS3000, CLASS6000, CLASS900. The standard of these products are in compliance with ASME B16.11.
Socket welding coupling
Pipes are put into socket welding hole and welded. Because of this connection, installation cost is reduced.
Threaded coupling, the type of thread is NPT.
For Npt Coupling, the length of thread will be mentioned under the standard ASME B16.11.
