With expertise in high-performance welded tubes, the company provides economical and dependable solutions adapted to suit a multitude of industrial applications. Employing sophisticated welding techniques and strict quality control processes, Vinit Stainless produces tubes with good dimensional accuracy, corrosion resistance, and surface finishes. These tubes come in different sizes, grades, and finishes to meet applications in construction, chemical processing, pharmaceutical, and others. With timely delivery, technical support, and customer-centric service, Vinit Stainless is a reliable ally in the stainless steel tube industry.
Vinit Stainless welded stainless steel tubing is basically offered in grades such as 304, 316, and 409. These consist of iron, chromium (18–20%), nickel (8–12%), and occasionally molybdenum (2–3% in 316) for improved corrosion resistance. The mechanical properties encompass tensile strength of between 500 and 750 MPa and yield strength between 200 and 500 MPa. Welded tubes possess superior formability, acceptable weld strength, and resistance to scaling at elevated temperatures. Though less uniform than seamless tubing, Vinit‘s welded tubes are of high structural integrity and are manufactured to ASTM, DIN, and ISO standards.

Stainless steel welded tubing are formed by welding stainless steel strips or plates. They offer strength, corrosion resistance, and cost-effectiveness, suitable for various industrial, commercial, and residential applications.
Stainless steel ERW (Electric Resistance Welded) tubing are produced by welding steel strips. They offer cost-effective, high-strength, and corrosion-resistant solutions for various industrial applications, providing durability and reliability.
Stainless Steel EFW (Electric Fusion Welded) tubing are produced by electrically fusing stainless steel plates or strips. They offer high precision and strength, suitable for high-pressure and demanding applications.
SS HFW (High-Frequency Welded) tubing are stainless steel tubings welded using high-frequency currents. They provide strong, precise joints, making them ideal for structural applications and high-strength requirements.
Stainless Steel butt-welded tubing are joined by aligning and welding the ends together. This method creates strong, leak-proof joints, ideal for high-pressure and high-temperature applications in various industries.
Stainless Steel laser-welded tubing use laser technology for precise, clean welds. They offer high accuracy, minimal thermal distortion, and are ideal for applications requiring tight tolerances and smooth finishes.
The tests include destructive testing methods and others which do not destroy the material but analyze the testing quality. We are developing into all modern aspects. Offering services to any customer that provides security assurance, we live achievement and a few policies such as consideration of diversity and advantage of best quality, quality reputation, and our name in the industry. Best quality speaks for itself, especially when the customer is satisfied after delivery. Logistical support at the most convenient part to ensure that shipping for emergency stock and standard packing materials is done correctly.
Vinit Stainless welded stainless steel tubing is used extensively in industries where high corrosion resistance and structural stability are needed. In the construction sector, it is applied to handrails, fencing, and structural supports. The food and beverage industry depends on welded tubes for sanitary piping and fluid transfer systems. In the transport and automotive industries, tubes are employed in exhaust systems, fuel lines, and decorative trims. They are also needed in heat exchangers, water treatment facilities, and architectural structures. Economical and versatile, welded tubing is specified where high accuracy and uniform wall thickness are paramount to function.
