Product Description

Zirconium Coil tube ,corrosion-resistant zirconium heat exchangers , UNS R60702

Custom manufacturer of corrosion-resistant zirconium heat exchangers. Types are chemical, shell, and tube heat exchangers. Production of zirconium coil tube for heat exchanger and cooler, Corrosion resistant R60702.

 

  • Description

Zirconium coil tube

Used in enamel reactor, steam heating in glass fiber reinforced plastic reactor and circulating water cooling. The one-shot molding process uses a single-sided welding double-sided forming process to ensure the quality

 

According to the heat exchange area and pressure, there are usually size:

57×3,57×2.5,45×2.5,38×2.5,38×2,32×2.5,30×1.5,25×2,25×1.5mm etc., can be produced according to user requirements. In addition, we can also provide a variety of shaped pipe fittings, such as serpentine tubes, U-shaped tubes, etc.

Features: It has strong corrosion resistance, good thermal conductivity and long service life.

 

Zirconium coil tube are suitable for various concentrations of hydrochloric acid, acetic acid, phosphorous acid, phosphoric acid, nitric acid, formic acid, acetic acid, oxalic acid and their corresponding salt solutions.

 

Corrosion resistance of zirconium tube:

Zirconium is a reactive metal with a strong affinity for oxygen. When zirconium is in an oxidizing medium, the surface spontaneously forms a protective oxide film having a very good adhesion. This oxide film has a very high self-healing ability in the presence of oxygen, and can protect the zirconium substrate from corrosion at 300C. Therefore zirconium is a corrosive metal. Its chemical stability is similar to that of precious metals and silver, and is superior to nickel and alloys, and also stronger than high-grade stainless steel and its alloys. In general, the corrosion resistance of zirconium in acid is slightly inferior to that of bismuth, and the corrosion resistance in alkali is better than that of cerium zirconium. One advantage is the corrosion resistance of reducing acid, that is, in sulfuric acid, hydrochloric acid, etc. The acid has excellent corrosion resistance, which is precisely the deficiency of titanium in corrosion resistance. Zirconium is very resistant to corrosion in most inorganic acids, organic acids, alkaline solutions, salt solutions and certain molten salts. However, it is not resistant to corrosion in a few media such as hydrofluoric acid, ferric chloride, copper chloride, aqua regia, concentrated sulfuric acid, and wet chlorine. It also has corrosion resistance to high temperature and high pressure water, steam and liquid metals.
