Pressure rating of flange
According to ASME B16.5, steel flanges have seven pressure classes: Class150-300-400-600-900-1500-2500. The pressure level of flanges is very clear. Class300 flanges can withstand more pressure than Class150 flanges, because Class300 flanges need to be made of more materials, so they can withstan...Read more -
How to improve the corrosion resistance of stainless steel
(1) The anode polarization curve of the stainless steel has a stable passivation zone for the specific medium used. (2) Improve the electrode potential of the stainless steel matrix and reduce the electromotive force of the corrosion galvanic cell. (3) Make the steel with single-phase structure...Read more -
Types and working principle of condenser
Condenser is one of the main heat exchange equipment in refrigeration unit. Its task is to discharge high pressure superheated refrigerant vapor from the compressor, through which heat is released to the environmental medium and cooled, condensed into saturated liquid, or even supercooled liquid....Read more -
Welding process to reduce welding deformation
The methods to prevent and reduce welding deformation must consider welding process design and overcome the variation of hot and cold cycles during welding. Shrinkage cannot be eliminated, but it can be controlled. There are several ways to reduce shrinkage deformation. 1 Do not weld too m...Read more -
Basic knowledge of bursting disc
1 Combined application of safety valve and bursting disc 1. The bursting disc is installed at the entrance of the safety valve — the most common advantage of this setting is that the bursting disc will isolate the safety valve and the imported process medium, and the system has no l...Read more -

The detailed classification of pressure vessels doesn’t get any clearer than this!
Pressure vessels have a wide range of use, a large number and complex working conditions, and the degree of harm caused by accidents varies. The degree of hazard is related to many factors, such as design pressure, design temperature, medium hazard, mechanical properties of materials, use occasio...Read more -
Several reasons why steam pipelines need to be decompressed
When steam is output from the boiler at high pressure and then transported to the steam point of each equipment, decompression control is usually carried out. Why does steam need to be decompressed? The main reasons are as follows: 1. The boiler usually produces high-pressure steam, which ...Read more -
What is stainless steel wire drawing and polishing?
The difference between brushed stainless steel and polished! In terms of technology, the wire drawing process is to make a regular and uniform surface pattern on the surface of the workpiece. The general drawing patterns are: thin stripes and circles. The polishing process is to make the surface ...Read more -
The principle of the separator is still unknown? Pipeline transportation and separation of materials are impossible without it!
When we use pipelines to transport medium, if there is liquid water in the medium, it will accelerate the corrosion of the pipeline; if there are solid impurities in the medium, it will cause blockage of pipelines and equipment. Impurities in these media will not only reduce the transmission effi...Read more -
The difference between TIG, MIG and MAG welding! Get it all at once!
Differences between TIG, MIG and MAG welding 1. TIG welding is generally a hand-held welding torch and the other hand-held welding wire, which is suitable for manual welding of small-scale operations and repairs. 2. For MIG and MAG, the welding wire is sent out from the welding gun through the au...Read more -
