As a  Railway Fastening System Manufacturer , let's analyze why the Fish Bolt has failed. 1. The connecting rod of the diesel engine is divided into several levels. In the inspection, it should be noted that different levels of connecting rods cannot be used. If the sloppy handle is messed up during the overhaul, the joint of the big joint of the connecting rod will not be tightly fitted, which will cause the connecting rod cover to loosen during the engine operation and cause the breakage of the connecting rod bolt of the fishplate. 2.Foil Bolt material problems, machining defects and heat treatment process problems can also cause the connecting rod bolts to break during engine operation. 3. The tightening torque is too large during assembly, the force is not uniform, and the tightening torque is too large, exceeding the yield limit of the  Fish Bolt  material. The connecting rod bolt is subjected to yield deformation and is broken by excessive elongation under th...

Rail bolts in railway fittings are used in railway construction to ensure that they are applied to a predetermined track. In most cases, when a new rail system is made of concrete for the track, instead of they are traditionally fixed timber. In order to ensure the track of the concrete, the track has to be fixed into the concrete, and the rails of the track are held in place by using a mounting bracket. The front rail can be applied to the mounting bracket and the mounting bracket is secured to the concrete. As a  Railway Fastening System Manufacturer , ZHONGBO will give you a detailed introduction to the application of rail bolts. Since the track system must withstand any given weight at any given time, the stronger the anchoring system, the better, to prevent any possible transfer. Therefore, the mounting brackets, as well as the rail bolts, are made of hardened steel. The steel is also treated to prevent it from becoming rusting. These installed systems are mounted directly ...

There are many types of railway accessories, which are roughly divided into three categories of accessories, each of which has its own special existence. As a  Railway Fastening System Manufacturer , TAICANG ZHONGBO will tell you about it. 1. Railway track connecting fittings, one is the connecting fittings of the same side rails, and the other is the connecting fittings between the parallel rails. Commonly used connecting components between parallel rails are gauge rods, gauge feet, and other link accessories. The general gauge pull rod is a common rail connection accessory in railway accessories. In special cases, the insulated gauge rod is used. The ball splint is an indispensable accessory in the railway track connection and is used for the connection between the rail and the rail. 2. Railway track products, one is railway rails, and the other is products such as ballasts and cores in railway tracks. The laying of railway rails in railway transportation is the basic co...

In order for railway fasteners to function better, regular maintenance is required during use. Regularly cleaning the fasteners will increase the efficiency of the fasteners. As a  Rail Spike Manufacturer , let us introduce the six common problems in  Railway Fastening System   cleaning. 1. Pollution when rinsing Cause: Rinse is not caused by silicate remaining on the surface of the fastener. 2. Unreasonable stacking of fasteners Cause: The fastener is contaminated by cleaning agents and quenching oil during the rinsing period, melts at the heat treatment temperature, leaving a chemical burn scar, which confirms that the surface of the fastener is not clean. 3. Surface residue Cause: No acid cleaner was cleaned and the concentration of lye in the rinse tank was not frequently checked. 4. Alkali burns Cause: The red area on the tested screw is caused by alkali burn. The alkaline cleaner contains chloride and calcium compounds, which will burn the steel...

A  Rail Spike  retains the trail set up. It isn't exposed to wear such as the monitor is. It has to be powerful and hard to perform its job. If a steel has a high carbon content and is heat treated so it's challenging, it gets more brittle. Should you hit it with a hammer, then it is going to crack. But  Railway Bolts  that’s bent can still do its job. So the metal needs to be soft enough to bend without shattering. Rail Spike Manufacturer  said rail spikes usually aren’t an exact equivalent though. If anything, they’ll have less carbon and therefore won’t get as hard. Sometimes they’ll be a bit of an alloy, with metals like copper mixed in to help make them more malleable. This will further help to prevent cracking. If you would like to cut on a HC railroad spike automatically (like using a blade rather than having a cutting torch) then you might wish to anneal it. Annealing will soften the alloy so you are able to work with this.
