High Purity Stainless Steel Tubing | High Purity Gas Tube

High Purity Stainless Steel Tubing | High Purity Gas Tube | High Purity Pipe Fittings

High purity stainless steel tubing is widely used in various industries where high purity, high cleanliness, and high performance are critical required, such as semiconductor industry, sports, pharmaceuticals, laboratory engineering, high purity gas industry, and more. As mostly this kind of tubing is mostly used to deliver various kinds of high purity gas for different applications, it is also known as high purity gas tubing as well.

As one of the top quality China precision stainless steel tube manufacturers, Younglee produces and supplies high purity tubes in a wide range of metric sizes and imperial sizes. Our customers include many respected companies in China & oversea countries.

Easily distinguishing tips between 304,304H and 304L

304,304H and 304L, What is the difference?

In fact, according to the content of chromium and nickel ,they are all 304 stainless steel, the composition is containing 18% chromium (Cr), 8% nickel (Ni), but the main difference is the percentage of carbon between them.

Stainless steel products you may be interested in:

304, 304L, 304H chemical composition (%) table

304L is ultra-low carbon stainless steel, the carbon content is down to 0.03% or less, to avoid intergranular corrosion, and the effect of stress corrosion resistance is better than 304 in theory, but in practice the effect is not obvious. Reducing the carbon and adding titanium can achieve the same effect, but adding titanium which is 321 stainless has higher smelting costs, the price is more expensive.

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.
