Think you know stainless steel? Not enough

Stainless steel is widely used in various industries and our life. But do you think you know enough about stainless steel? Even if you are some engineer in the steel industry. Here I’d like to write an article of detailed introduction of stainless steel.

This article focuses on the types and characteristics of common stainless steels, as well as the main purpose. Continue reading →

What are the advantages of stainless steel tube heat exchangers and brass tube heat exchangers?

AS many people may know there are two typical types of tubes to constructing heat exchangers, which are seamless stainless steel tubes (including duplex stainless steel tubes S31083, 2205, S32750, 904L, etc) and brass tubes. But what are the advantages and disadvantages of this two different heat exchangers?

Stainless-steel-heat-exchangers-compared-to-brass-tube-heat-exchangers

In fact, the biggest difference is not the heat transfer performance, corrosion resistance is good or bad, but is that copper tubes are less prone to fouling than stainless steel tubes, which many people might do not realize. To give a simple example, some commercial boilers are used without water treatment equipment, but using life is as long as 15 years. The reason is that although the water can foul scale in the copper wall, but it is only flocculent fouling, in this case, as long as we increase the flow of water, fouling scale can not precipitate down.

Take you to the ferrite stainless steel- the type and characteristics

The reason why stainless steel is “stainless” is due to the chromium contained in it has a significant corrosion resistance.

Ferritic stainless steel is no exception.

Ferritic stainless steel is the main element of chromium (≥10.5%) and iron, and some grades only chromium, some grades in addition to chromium, but also contains other elements (such as Mo, Ti, Nb, etc.) to get some special performance. Continue reading →

Looking for safety pipe connectors for hydraulic pipes?

Flanges are the most popular components in pipe and tube installations in industries, they are used to connect pipes or tubes. For most of the applications, the normal flanges are enough to provide good connection to pipe lines. However, for pipes under high pressure, such as hydraulic tubing, are they normal types of flanges still safe?

No! To provide safety and leak-free connection of the tubes and pipes under high pressure, the best way is that we use certain type of SAE Flanges.
