While grade 304 may be considered to be a very versatile and popular alloy grade, ASME SA312 grade 316 pipe follows close behind. This being said, Stainless steel 316 pipe is a much better alloy in terms of not only mechanical properties but also corrosion resistance.

Hence, the aisi 316 pipe is often contemplated in those applications where properties superior to that of alloy 304 are required. Take for e.g. the textile industry. Since textiles can be manufactured both synthetically as well as through naturally available raw materials, the processing of each type of fibre is different. Usually cotton or linen are fibres that are scoured and bleached to remove impurities.

These processes use various kinds of salts and soaps or chemical solutions which if exposed to grade 304, would surely be susceptible to getting corroded. On the other hand, the highly resilient behaviour and superior tensile strength properties of ASTM A312 tp 316 seamless pipe make this alloy grade an amazing addition to the textile industry. Moreover, the dyeing of different textile fibres often uses an assortment of techniques with varying chemicals. Some of the fibres such as nylon or silk use acids like acetic acid to facilitate the increase of dye uptake by the cloth.

Since 316 Stainless Steel seamless pipe offers good resistance to acetic acid and phosphoric acid, they can be involved in the dyeing process as well. Other fibres like cotton can increase the uptake of dye by adding salts to their dyeing bath. As the SS 316 seamless pipe is resistant to salt solutions, they can be used in several processing operations of the textile industry.

What's New ?

In India there are many manufacturers produce Stainless steel 316 Seamless and welded pipe. But when you go to buy a seamless pipe in specific size and in small quantity from stockist or supplier, it may cost you extra so always ask the price of standard size first in seamless and ERW both and get the idea of price difference in India for better deal.

Strength difference between stainless steel 316 seamless and welded pipe

The strength is different in different types of material and methods of production. The pipes are produced in welded or seamless conditions. The seamless pipes are produced through drawing them from a single billet where the wall thickness is even and there is no joint in between two parts of the pipe. So the strength is evenly distributed. The welded pipes on the other hand are welded from a strip of metal either longitudinally or spirally. In both cases, the welded joints are weak spots when it comes to pressure containment. So the welded pipes can operate up to 80% of the pressure levels where the seamless ones can operate.
