Refrigerantion pressure gauge raw materials have skills

Have already visited: 12608/20/2021  

There are many refrigeration pressure gauge manufacturers in the Chinese market, and the market retail price of the product is also from more than ten yuan to dozens of yuan. So how to identify the quality of refrigerant pressure gauges? It's not that the higher the price, the better. It is suggested that we should make a comprehensive analysis and consideration from the aspects of raw material procurement, pressure holding test, cleaning process, welding process, and precision of the product to choose the suitable product.

The selection of refrigeration pressure gauges is very important, quality products are pure SS304 stainless steel, 59-1 brass as the main parts. Some businesses in order to seek higher interests, use inferior stainless steel or directly with iron to replace.

Raw materials also include movement, oil, glass, and so on. How do you choose these materials? The material of the movement can be copper alloy or pure brass. Take the VAB stainless steel shock-resistant refrigeration pressure gauge as an example, its movement using imported well-known brand products, so the quality is excellent.

Why some refrigeration pressure gauge has not been used long inside the oil began to turn yellow hair black? This is largely related to oil. VAB stainless steel shock-resistant refrigerant pressure using imported oil can ensure that it is transparent throughout the life of the clear. In the refrigeration pressure gauge on the choice of the surface glass, high-quality glass can play a pressure resistance, shatterproof, explosion-proof role, and high transparency. Poor quality glass, on the other hand, runs the risk of blurring and shattering.
