Gayatri Tubes is a renowned name in supplying and manufacturing Duplex Steel S31803 / S32205 Compression Tube Fittings to its clients. We at Gayatri Tubes offer a superior quality Duplex S31803 / S32205 compression tube fittings. It is a combination of advance geometry with shapes. And manufacturers do it for the back ferrule and ferrule hardening process. We offer it in various shapes and product form like plate, sheet, seamless and welded tubes. Compression tube fitting of this grade still is the most successful and commonly used product. S 31803 and S 32205 are very popular ferritic – austenitic steel grades. Many industries make use of Duplex 2205 Tube Fittings for several industrial applications worldwide.
It exhibits enormous strength even at very high temperatures and par excellence corrosion resistance properties even in the presence of acidic substances. Due to this many industrial processes make use of this grade steel compression tube fittings. These fittings are exceptionally hard and give a sound grip while holding the fitting. These are much harder and sturdy that its counterparts. These grades of stainless steel are the most durable tube fittings amongst all tube fittings available in the market. They remain leak-free and intact for a long period of time. It is a formidable product that is a result of strong power and instrumentation applications. It comes with a silver-plated nut which increases its life span of tube fitting. These tube fittings are resistant to galling. Galling is effect on the steel due to fluctuations across a range of cold to hot temperatures. That makes these suitable to work even in effect of very high temperature.
Duplex 31803 32205 Compression Tube Fittings are manufactured to meet the specifications. These standard specifications make it suitable for a wide range of applications in many industries. Such industries are hydraulic and chemical. It comes with a seal that makes it leak safe and gas leak safe that is how it becomes extremely safe to use in many industrial and home uses. It is convenient to install. This is a wonderful and economically viable product and that is why it is quite popular.
