  It is common to see some of the   Railway Bolts  cross recesses black, or the thread is black and the wash is not clean. So what is the reason that the Railway Bolts can't be washed clean? How can I better solve the blackening phenomenon of Railway Bolts?   Rail Spike Manufacturer   tells you about the causes and solutions of Railway Bolts. Bridge Bolt is usually black because of the high heat generated during cold or tooth decay. Usually occurs in the cross section. In the production process, the heat can be dispersed in time through the supply of lubricating oil, and the speed of the machine can be appropriately adjusted to avoid problems. Of course, in addition to the technical reasons for the Bridge Bolt black, it is also possible that the material problem of the Bridge Bolt itself will also cause the surface of the stainless steel screw to blacken. Bridge Bolt Bridge Bolt  blackened solution: Degreasing - water - cross tank cleaning agent - water - n...

  Normally, the Rail Anchor Bolt is not easy to break when it is used. Only in special circumstances, the Rail Anchor Bolt will break. Why does the Rail Anchor Bolt break? What is the real reason for its break? According to the summary,   Anchor Bolt China Exporter   tells us that there are four common breaks. Anchor Bolt 1. The quality of the raw materials used by Rail Anchor Bolt, the quality of the wire is not good. There are many impurities, impure, resulting in insufficient hardness. 2. When the customer uses the  Anchor Bolt , the force is too large. Generally, you can do a lower torque test to see what the minimum breaking force is, and then adjust the torque. If the screw torque is required to be high, the screw should be heat treated. 3. Production process problems. For example, the Anchor Bolt with a biased eccentricity, and the Q value is too deep and the R-bit design is too small when the undershoot is produced during manufacturing. 4, see if the pre-hole...

  China's rail transit industry can be said to be developing at a rapid pace. It is not only the continuous optimization and improvement of domestic rail transit construction, but China's rail transit strength has been recognized and praised internationally. Today, China's rail transit equipment companies have become one of the world's leading phalanx, with world-leading R & D and manufacturing capabilities, comparable to any international giant. Many countries have cooperated with China to build rail transit projects in their own countries. The Boston Metro and even the US subway are the world's largest international giants, but in 2014, in the history of the American subway, the mark of Chinese manufacturing was engraved - the subway car of China North Car successfully entered the United States.

  As a   Rail Spike Manufacturer , let's share with you the application standards for rail bolts. According to the relevant railway standards, at least two sets of bolts are required for each rail joint to be fastened, each bolt is tightened to a torque of approximately 400 ft., and the product itself needs to be between 25,000 and 30,000 lbs. A) Bolts must be properly sized according to the standard and tightened in place. B)  Rail Bolts  must use spring pads and nuts. C) The nut used with the bolt can be selectively mounted on the inside or outside of the rail. Rail Bolts D) When the bolts and fishplates are removed from the rail, the contact surface with the rails should be clean. The threaded part must be oiled. E) Safety standards require replacement and installation of missing and damaged bolts in the rail connection. Our company specializes in providing a variety of railway fasteners such as  Rail Anchor Bolt . It can also be customized to your requiremen...
