Virgin engineers are the leading manufacturer, exporter, and trader of the excellent quality of Stainless steel 317 / 317L instrumentation tube fittings. We have developed all ranges of product at the highly equipped inventory that is resulting in making those greatly reliable and durable as well. These tube fittings are further classified into different categories like austenitic, ferritic and martensitic types that are based upon the crystalline structure. These are delivered to the global industrialists and are used in many industrial applications. It is offered to the buyers at different standards, outer diameter, working pressure and end connections.
The product is having some good features to offer due to which it has become highly popular among the numbers of industrialists. It has the ability to easily withstand high temperature, vibrations, and shocks. These fittings are having very good creep strength and are resistant to intergranular corrosion because of the addition of niobium alloying element. Also, it resists nitric and mildly acidic solutions.
Alloy information to know-
Alloy SS 317 is austenitic nickel and chromium SS that is having corrosion resistance ability. The high molybdenum content is improving the alloy excellent pitting resistance properties. It is the high corrosion resistant of series 300 and possesses the creep strength and high tensile strength properties at very high temperature.
Alloy SS 317L is low carbon austenitic nickel and chromium stainless steel that is used in the applications wherein annealing is not at all possible after welding and also corrosion resistant is required. The alloy is giving very good oxidation resistance at the intermittent service to 1600 Deg F and in continuous services to 1700 Deg F.
Manufacturing of the tube fittings-
There in the highly equipped industry, the production of Stainless steel 317 / 317L instrumentation tube fittings are done with full care. We have a clear aim of making the superior quality of the product using well tested high quality of the product. There at the time of production of tube fittings, the manufacturers are taking help of newest technology and machinery. This guarantees good dimensional accuracy and fine surface finishes. The designing of it is done by keeping in mind several raw material quality standards and manufacturing norms set up by the producers.
Testing of the tube fittings-
These tube fittings before shipping to the respective buyers are well tested for checking the quality. The testing conducted is like positive material identification test, hardness test, macro test, micro test, intergranular corrosion test, pitting resistance test, chemical test, mechanical test, flattening test, flaring test, etc.
The documents offered-
The documents offered to the buyers are including commercial invoice, packing list, heat treatment chart, quality assurance plan, NABL approved lab test report, etc.
100% radiography test report, third-party inspection report, buyers report, mill test certifications as per EN 10204/3.1B, etc. are TC offered to the buyers.
