铁路罐车近20年来发展很快,目前,美国大约有铁路罐车17万辆,占铁路货车总数的10％,法国犬约有4万辆,其他一些工业发达国家这种率的数量和品种也在不断增加。为满足日益发展的化工产品的运输要求,提高运输效率,铁路罐车主要向大型化和结构完善方面发展。为保证运输安全,装卸装置和安全装置应逐步完善。一、罐体内表面施涂保护层铁路罐车运输多种化工产品,大多数化工产品有腐蚀作用。为保证罐车使用寿命就要有一定的腐蚀裕量,造成自重增大,成本提高。罐车罐体内表面施涂保护层,可大大
At present, there are about 170,000 railway tankers in the United States, accounting for 10% of the total number of railway wagons and about 40,000 French dogs. The number and variety of such rates in other industrialized countries are also increasing. Increasing. In order to meet the transportation requirements of the increasingly developed chemical products and enhance the transportation efficiency, the railway tankers mainly develop towards large-scale and structural improvement. In order to ensure the safety of transport, loading and unloading devices and safety devices should be gradually improved. First, the inner surface of the tank to apply protective layer Railway tanker transport a variety of chemical products, most of the chemical products have a corrosive effect. In order to ensure the service life of tankers must have a certain amount of corrosion allowance, resulting in increased weight, cost increases. Tanks applied to the surface of the tank protection layer can be large
