Depiction of the alloy
321H is the austenitic titanium stabilized stainless steel which is well known for its general corrosion resistance ability. The alloy is used to design the equipment which works within the carbide precipitation environment. These can be hardened only by cold working and in the annealed conditions they are non-magnetic. It contains all the properties which are required to resist the corrosion.
Features of these tubes
Our tubes are well-recognized for its sturdy construction, smooth finish, super strength, elegant design, high efficiency, high durability, and corrosion resistance ability. Stainless Steel S32109 Seamless Tubes have many weldability and machinability property. We are appreciated by the clients who buy these tubes and our manufactured tubes are well-known among all the industries. Among all the tube manufacturers we are the leading developers of the steel tubes.
The Stainless Steel 1.4878 Welded Tubing are manufactured by trained and skilled employees. With the help of superior quality of alloy which is collected from the reliable market vendor. The quality checkers check the alloy so that no harmful content is mistakenly added in the manufacturing of the tubes. Well-established and latest machinery and tools are used to develop the superior quality of stainless steel tubes. For the 100% smoothness and thickness the tubes move through various stages in the manufacturing process.
Moreover, the process carried on under the stringent supervision of the hired professional experts. They have excellent knowledge about the guidelines and rules required to manufacture the tubes. These experts check all the quality and norms that are required to develop the stainless steel tubes. Also, they encourage the employees in such a way to achieve the goals of the organization.
Testing of the material used
The quality controller makes the Stainless Steel 321H Tubes to moves through certain tests to ensure that the quality is maintained by the employees. And to ensure the clients that no harmful product is delivered to them. Some tests performed are-
• Flattening test
• Flaring test
• Chemical and mechanical test
• Micro and macro test
• Hardness test
• Hydrostatic test
Other than these tests the tubes go through many inspections to check the quality of the tubes. Some of the inspections that are conducted are third-party inspection and visual inspections. These inspections are conducted by the third-party inspection squad who has good knowledge about the manufacturing guidelines of the tubes.
Documentation of the tubes
We offer certain documents along with the delivered tubes to our patrons. This satisfies our clients that the product has been manufactured by as per the specification that was provided by them. Some of the documents which are attached are-
• Commercial invoice
• Radiography test report
• Chemical test report
• Guarantee letter of the company
• Quality assurance plan
• Packaging list
Packaging of the tubes
The Stainless Steel 321H Tubes are covered with the poly bags which protect the tubes from extreme weather conditions. These tubes are then placed in the wooden boxes, wooden pallets, and wooden crates. This prevents them from getting rust during the shipment process. All the product details are attached to the wooden boxes.
