Virgin Engineers is leading a professional venture that is offering an abundant quality of Stainless Steel 904L Instrumentation Tube Fittings in varied ranges. We give first priority to the quality; therefore we efficiently work hard and put great efforts to achieve a quality standard product. In addition to it, we acquire the premium quality of raw material for its fabrication that is sourced from the reputed vendors. Even more, we have the great support of most qualified and technically sound professionals that aids to achieve a global standard product. Furthermore, we set up the innovative technologies and highly advance machinery in our manufacturing plant to supply high-quality products. We are a customer oriented firm that adheres to fulfill the requirements and desires of our customers. To fulfill their requirement we cater our product in custom made shapes, size, length, grade, dimension and thickness according to them.
Stainless Steel 904L Instrumentation Tube Fittings is one of the ranges of tube fitting that is generally used for vacuum, high temperature, and pressures applications. These fittings have a superior leak-free sealing system in high impulse and in high thermal stresses. This grade of tube fittings ensures a great level of safety and are ensures superior leak-tight seal after re-assembly and assembly.
These alloys of fittings are non-stabilized austenitic stainless steel alloy having low carbon content. In addition to it consist of nickel, chromium and copper content also. These tube fittings are mainly utilized in those circumstances where the corrosion resistance of other grades is not adequate. The inclusion of copper content shows good resistance to sulfuric acids and other reducing media in both mild and aggressive surroundings. Furthermore, these fittings are greatly immune to crevice as well as stress corrosion cracking in soaring temperatures.
Due to high nickel and molybdenum content, this range of alloy fitting performs well in comparison to other grades. In all circumstances, the fittings remain non-magnetic and exhibit superior weldability and formability. Even down to cryogenic temperature, the austenitic structure of the fittings facilitates good toughness and hardness. The fitting also exhibits good formability, ductility, and durability in tough climatic circumstances.
Similarly, these fittings exhibit superior resistance to oxidation and pitting corrosion in chloride solutions. At the temperature of 1090 to 1175 degree C the fitting are solution treated and are rapidly cooled. On the other hand, to achieve great weldability these are welded by all conventional methods.
Several types of testing and quality checking are performed on the different stage of production as to carry out error-free and finished quality product. Such test is like hardness test, mechanical test, pitting resistance test, chemical analysis, tensile strength test, macro/micro test, ultrasonic test. Other more test are PMI test, radiography test, IGC test, flaring test, flattening test and third-party inspection.
We assure to maintain the quality of the product from any of severe damage and scratches occurred during the transit. So to avoid all these troubles we properly packed the products in wooden cases, wooden pallets, wooden boxes, and wooden cartons and in wooden crates.
