Stainless Steel 347 Pipes

Piyush Steel is a well-known distributor and supplier of Stainless Steel 347 Pipes. The pipes are basically a tantalum/columbium stabilized austenitic nickel-chromium stainless steel. Stainless steel pipes are highly advantageous for extreme temperature services where good mechanical properties are required. The stainless 347 pipes have improved corrosion resistance properties in the oxidizing environment. We fabricate as well as design the 347 pipes in various designs and specification as per the client requirement. Thus pipes are made available on various aspects. It is then passed the quality test so as to meet the standards. Well recognized characteristics like sturdy construction, non-corrosive, easy to install, durable finish, reliable, and other things as well are offered. The outer diameter is measured in NPS and the range can be measured in NB. The chemical, mechanical, and physical composition is kept in such a way that it forms an appropriate product that can be used in industries.

Some of the application of 347 pipes includes high-temperature steam service, boiler tubes, heat exchanger tubes, high-temperature processes, and radiant super-heater.

About SS 347 pipes-
The Stainless Steel S34700 Seamless Pipes are basically an austenitic SS stabilized pipes by addition of tantalum and columbium so as to reduce or protect carbide precipitation in service at high temperature up to 800 Degree F and during welding at 1650 degree F. It can be stated as chromium nickel steel that got modified through the addition of tantalum and columbium. These SS 347 pipes along with tantalum-columbium allow withstanding at high temperature as it possesses good mechanical properties. This thus makes the pipes suitable for service in a low-temperature environment or in aqueous. It possesses good resistance toward inter-granular attacks. The SS 1.4550 Welded Pipes are developed in such a way that it has enhanced creeping resistance for greater strength at temperatures above 537 Degree C or 1000 degree F. They are designed in various dimensions, wall thickness, size-seamless pipes, schedules, form, end, length, types, and standards. The SS pipes possess sub-zero notch ductility and ambient ductility. It can be used successfully and is appropriate when high strength is needed. It exhibits a thermal expansion coefficient, high heat conductivity, and is suitable for working at 3000 degrees C temperature.
The strength can be increased abruptly and thus it can be made cold workable with high proof stress and low elongation. It is used mainly in oil and gas, chemical processing and marine environments.
