Consideration of Heat Treatment in Pressure Vessel Design
Welding of important components, welding of alloy steel and welding of thick parts all require preheating before welding. The main functions of preheating before welding are as follows: (1) Preheating can slow down the cooling rate after welding, which is conducive to the escape of diffusible hyd...Read more -
Are you using the right emulsification homogenizer?
The effect of emulsification and homogenizer in all walks of life is getting bigger and bigger, and it has penetrated into many fields. For example, the loose shearing of coatings and fuel additives are new breakthroughs in homogeneous emulsification technology in the fuel industry. They can be w...Read more -

The purpose of the emulsification pump
The emulsification pump is a device that efficiently, quickly and uniformly transfers one phase or multiple phases (liquid, solid, gas) into another immiscible continuous phase (usually liquid). In general, the phases are immiscible with each other. When external energy is input, the two material...Read more -
How does CBD work on hormonal imbalances?
Hormone imbalance occurs when we have too little or too much of one or more hormones in our body. Hormones play a very important role in regulating our health, and the slightest hormonal imbalance can cause a lot of problems. This is because the hormones produced by the endocrine system are essen...Read more -
How much do you know about the role of “it” in beer?
The alcohol in beer has a certain influence on the foam and taste of beer. The alcohol content is high, the beer viscosity and foam viscosity are also high. The beer foam without alcohol is extremely unstable; the wort foam with hops does not hang in the cup, but After adding alcohol, the glass h...Read more -
The safety hazards of the reactor are as follows…
In recent years, the leakage, fire and explosion accidents of the reactor have occurred frequently. Since the reactor is often filled with toxic and harmful chemicals, the consequences of the accident are more serious than the general explosion accident. The hidden danger of reactor safety cann...Read more -
What is the difference between rotor pump, centrifugal pump and screw pump
Many friends will encounter such a problem when choosing pump products. Rotor pump, centrifugal pump and screw pump are silly and unclear, and they don’t know which one they should buy is better. If you want to buy the right product, you must know the basic difference between these pumps. I...Read more -
Do you know the design principle of multimedia filters?
The meaning of filtration, in the process of water treatment, filtration generally refers to the process of retaining suspended impurities in the water with a filter material layer such as quartz sand and anthracite, so that the water can be clarified. The porous materials used for filtration are...Read more -
Example Welding of Large Tanks–Double-Arc Process on Both Sides
The welding quality of the welding seam of the stainless steel pressure water tank directly affects the safety of the pressure vessel. There are many welding methods, argon arc welding is one of the ideal welding methods, but when the diameter is greater than 800mm and the volume is relatively la...Read more -
Talk about the triangular relationship between nominal pressure, design pressure and working pressure
1. What is the nominal pressure PN (MPa)? The reference value related to the pressure resistance capacity of piping system components refers to the design given pressure related to the mechanical strength of piping components. The nominal pressure is generally expressed by PN. (1) Nominal pressur...Read more -
