Virgin Engineers understands and fulfill the ever-changing demands of the dynamic and global engineering industries over the decades. We are proudly associated with engineering industries which are dealing in tube fittings. We introduce the whole new range of Stainless Steel 321 / 321H Instrumentation Tube Fittings in global markets due to its prominent features offered to any applications. We deliver all standard and non-standard dimensions tube fittings in various specifications, grades, shapes, designations, and finishes. We also customized the tube fittings in order to meet the customer’s product requirements. We have a strong sourcing network across the world to buy the qualitative range of raw materials. We are equipped with a large inventory to meet the demands of dynamic and unpredictable markets so our customers quickly adjust to the sudden changes.
Know in brief about 321/ 321H grade:
Alloy 321 is a stabilized titanium grade with corrosion resistance. It has outstanding resistance to intergranular attacks. these tubing can be exposed in the chromium carbide precipitation range between the temperatures 800 deg F to 1500 deg F. these tube fitting oppose oxidation up to 816 deg C. it has higher creep and stress rupture properties than standard grades. Stainless Steel 321 / 321H Instrumentation Tube Fittings offer service in down temperatures. Alloy 321H is the higher carbon version and it is also known as UNS S32109. These tube fittings are designed for excellent fracture toughness. Both grades are dual certified and have higher carbon chemistry. These tube fittings are manufactured from both hot and cold working process. The manufactured range of tube fittings can be exposed in the heat treatment or annealing process. This operation furnishes the structure of grade and improves its ductility. These instrumentation tube fittings have the ability to oppose the pitting and crevice corrosion. These tube fittings can be applied in the higher temperature environments without the concern of distortion.
Why quality policy is implemented in our firm?
Since, the engineering products come in the demand and sometimes in hostile and super specialty applications; our aim is to provide a qualitative range of products. Quality is the lifeline of any business and we believe that. We are committed to satisfying our customers by providing high-quality products. We encourage our research & development team to upgrade the quality of products every day. The product quality is improved by conducting material examination regularly. The test performed on the tubes are flattening test, pitting corrosion test, compression test, tensile test, leakage test, hardness test, PMI test, macro test, and chemical analysis. Other tests are the mechanical test, micro test, IGC test, flaring test, ultrasonic test, radiographic test, etc.
We also provide test certificate to our customers, these certificates are 100% radiography test report, raw material certificates and third-party inspection reports.
The Stainless Steel 321 / 321H Instrumentation Tube Fittings are supplied by us in the industrial standard packing such as wooden crates, cages, boxes or customized packing. The tube fittings are supported by plastic end cap support to prevent jerks and damages while exporting.
