ASTM A269 Stainless Steel 316/316L Welded Coiled Tubing ISO in Oil And Gas

316/316L Welded Coiled Tubing:

316/316L Welded Coiled Tubing is made of austenitic stainless steel, which has good mechanical strength, welding performance and excellent corrosion resistance. It is especially suitable for medium-pressure fluid transportation in chloride ion or weak acid and alkaline environments. As a low-carbon version, 316L can effectively reduce the risk of intergranular corrosion in the heat-affected zone of welding and is the preferred material for various welding processes. Welded coils can achieve a continuous interface-free structure of up to thousands of meters, reducing leakage points. It is suitable for complex or high-demand scenarios such as oil and gas extraction, chemical injection systems, downhole measurement and control pipelines, heat exchanger tube bundles and heating systems. The product can be packaged in a wrap-around or coiled form according to needs, which is convenient for on-site layout and rapid deployment.

Factory advantages and features

MTSCO, which provides coiled tubing services, has been supplying quality products to the international geothermal, heat exchanger, shipbuilding, oil and gas industries since 2006. We can manufacture to various international standards covering major materials such as 304, 316, 2205, 2507, alloy 625, 825 and more. In recent years, we have made remarkable progress in the field of control line tubing, downhole control lines and chemical injection control lines, mainly producing welded/seamless continuous tubulars, single/multi-core control lines, capillary tubing and so on.

Choosing MTSCO has 5 advantages to give you peace of mind:

Firstly, our welded coiled tubing are available in lengths up to 33,000fts/coil.

Second, welded coiled tubing are hydrostatically tested to a max of 100MPA.

Thirdly, seamless coiled tubing can be up to 120kg/reel.

Fourthly, we offer various types of encapsulated overmoulding materials to meet diversified needs.

Finally, MTSCO coiled tubing have been awarded ISO/PED certificate, which provides a reliable certification of product quality and standard.


Quality Control Methods:

First, secondary inspection of raw materials. Our raw materials come from large factories such as POSCO,JISCO, ANSTEEL, ATI, NYK, Outokumpu, TSINGSHAN, Baosteel, WALSIN, ... Each batch of raw materials requires MTC and PMI. After the raw materials arrive, we conduct PMI and other inspections again to ensure that they meet the requirements. Second, traceability of the production process. The mainly production process includes welding, cold drawing, bright annealing and plastic wrapping. Each process is supervised by experienced engineers and technicians. Each link is supervised by professional qc inspectors and photographed for archiving. The entire process uses process cards to ensure accuracy and traceability. Third, 100% inspection before shipment. Siri Tubing has professional QC team to conduct a series of inspections and experiments on the tubes, including routine appearance, PMI, size, quantity, and other inspections. At the same time, we also conducts mechanical testing, hardness testing, airtightness,UT, ET, HT and other tests. All welded coiled tubing have passed 100% high-pressure testing,with a conventional testing pressure of 40MPa and a maximum of 100MPa. In addition, we also accept third-party inspection, such as SGS, TUV, and BV.
