Stainless Steel 304/316 Coiled Tube & Chemical Injection Line Supplier in India

Nishra Overseas is a leading manufacturer, stockist, supplier and exporter of Stainless Steel Coil Tubing in India, supplying SS 304, SS 316, and SS 316L Coiled Tubes for chemical injection lines, umbilicals, control lines, and heat exchange applications from our facility in Mumbai. Our coiled tubing reaches customers across Chennai, Bangalore, Gujarat, and international markets including Malaysia, Singapore, and Saudi Arabia.

Coil tubing is a continuous-length steel pipe supplied with a related surface treatment, wound onto a large reel or spool rather than cut into fixed lengths. Stainless Steel Coil Tubing offers excellent resistance to corrosion and oxidation across a wide range of process media, and is available with outer diameters ranging from as small as 0.125 mm OD up to 12 mm OD for fine-bore applications, and larger sizes for structural and process piping. Our Stainless Steel Coil Tubing Heat Exchanger grade tubing is engineered for superior strength and hardness, allowing it to transfer hot or cold fluids between vessels without deformation or cracking, even under repeated thermal cycling.

Stainless Steel Coiled Tubing is highly versatile and widely used across chemical industries in condensers, boilers, superheaters, and process skids. As one of the leading Stainless Steel Coil Tubing manufacturers in India, we focus on producing consistently high-quality tubing available to all customers at competitive, feasible prices.

What is Stainless Steel Coil Tubing

Stainless Steel Coil Tubing, also called SS Coiled Pipe, is manufactured as a continuous tube and wound onto reels rather than supplied as straight lengths, which reduces the number of joints needed on site and speeds up installation for long-run piping applications. 316 Stainless Steel Coil Tubing is used to transport a wide range of gases and fluids at high pressure and high temperature, offering strong resistance to acids and oxidizing media, and its ability to pump fluids without relying on gravity makes it well suited to complex routing in process plants.

304 Stainless Steel Coil Tubing is a lower-cost, high-efficiency option and is a preferred choice for open-hole mining and drilling operations, with a maximum hardness of 80 HRB. Our Seamless Stainless Steel Tubing Coil delivers high strength, with a minimum tensile strength of 30,000 PSI and minimum yield strength suited to demanding service, and is available in sizes from 4.76 mm to 25.4 mm. Welded Stainless Steel Coil Tubing is produced by joining steel pieces together with wall thickness between 0.5 mm and 4 mm, offering an easy-to-form, easy-to-install alternative for less critical applications.

Popular sub-ranges include 1/2" SS Coil Tubing, designed for high-temperature and high-pressure resistance and available in schedules from Sch 5 to Sch 160, and 1 Inch Stainless Steel Coil Tubing, offering improved safety and reliability for general industrial use. All grades are easy to clean and maintain over long service periods, and can be customized in chemical composition, size, and shape to suit specific project requirements.

Stainless Steel Coil Tubing Manufacturer in India

Nishra Overseas is a recognized Stainless Steel Coil Tubing manufacturer in India, producing SS 304, 316, and 316L Coiled Tubes and TPU/PVC-coated Seamless Coiled Tubing from our facility in Mumbai. Manufacturing directly in India lets us maintain tight control over chemical composition, wall thickness consistency, and coil winding quality — all critical for chemical injection lines and umbilicals where a single defect can compromise the entire run length.

As a manufacturer, we produce coil tubing in both seamless (ASTM A213 / A269) and welded (ASTM A249 / A269) construction, in grades from standard 304/316L to Duplex, Monel 400, Hastelloy, Inconel, and 904L for specialized corrosive or high-temperature service. Every coil is produced under process control covering chemical composition, mechanical testing, hydrostatic testing, and dimensional inspection, and is backed by mill test certificates and our ISO 9001:2015 certified quality system.

Stainless Steel Coil Tubing Supplier in India

As a leading Stainless Steel Coil Tubing supplier in India, we maintain ready stock of SS 304 and SS 316 coil tubing in standard OD ranges from 1/16″ up to 3/4″, along with larger seamless coil sizes, enabling quick turnaround for urgent chemical injection line and instrumentation projects. Our supply network spans Mumbai, Chennai, Bangalore, and Gujarat, supported by partner stockists in Malaysia, Singapore, and Saudi Arabia for faster regional delivery.

Sourcing directly from a manufacturer-supplier rather than through multiple intermediaries reduces lead time and cost while ensuring complete batch traceability from raw material to finished coil. We supply loose bulk wound coils on custom-size reels in accordance with ASTM A269/SA269, along with TPU/PVC coated tubing for corrosive or subsea environments.

Stainless Steel Coil Tubing Exporter in India

Nishra Overseas is an established exporter of Stainless Steel Coil Tubing from India, shipping SS 304, 316, and 316L coiled tubes, chemical injection line tubing, and umbilical tubing to project sites and industrial buyers internationally, including established supply routes to Malaysia, Singapore, and Saudi Arabia. Our export packaging is designed to protect coiled tubing during transit and prevent surface damage, kink formation, or contamination.

Our export team manages end-to-end documentation — including mill test certificates as per EN 10204 3.1/3.2, third-party inspection coordination (TPI), packing lists, and certificates of origin — so overseas buyers receive consistent quality and smooth customs clearance on every shipment, whether it's a trial order or a long-term supply contract.
