13Cr Stainless Steel API Spec Q1 Corrosion Resistant Coiled Tubing 2 3 / 8

Our products have complete specifications and can meet all working conditions. The outer diameter range of 13Cr tube we supply is from 1 1/4”(Ф31.75mm) to 2-3/8”(Ф60.325mm). All dimensions and corresponding parameters are listed in the table below, we can also customize it according to customers' requirement details.

Stainless steel coiled tubing is the widely used steel capillary tube which is ideal for use in potentially corrosive environments or transferring liquids and gases for cooling, heating, and other purposes. Stainless coiled tubing is made with the finest quality stainless tube by bent, curved, wound, or otherwise formed process around a hollow “center”. our 13Cr tube has the characteristics of restricted tolerance control, improved system ety and reliability, superior sealing performance, better corrosion resistance, etc.

Our manufacturing process generally includes: Raw material inspection → production → heat treatment → inspection & test → rewinding → packaging

We strictly control the purchase of raw materials, choose laser welding to minimize energy consumption and deformation. In the machining process we have layers of inspection to ensure the quality of the product. The inspection&test process generally includes dimensional inspection, non destructive evaluation(NDE) and hydrostatic test. We have two types of packing: wooden shaft and iron shaft.

Our core advantages (laser welding) :

Internal weld height: <0.3mm (long diameter for more types of operations)

Width of heat affected zone: <0.6 times the wall thickness

High availability: replacement of raw materials without replacement of the production line

Reliability: fusion welding > Pressure welding (resistance welding)

Groove corrosion: none

With the leading direction of producing High pressure extra long stainless steel control line tube(stainless steel coiled tubes), TIPTOP has become a high-tech industrial company integrating domestic research and development, production and sales. The company successfully developed a series of stainless steel testing cables in 2000. In recent years, the company has been committed to the research and development of duplex steel and nickel alloy control lines, and has been widely approved in the international market.

The company covers an area of 20,000 square meters and a building area of 12,000 square meters. The company has several stainless steel tube production lines, tube making units, tube drawing units, well-type electric furnaces, online vacuum light furnaces and other production equipment. The company also has a quality inspection center that meets the national stainless steel tube quality inspection requirements. The quality inspection center has a 300Mpa hydraulic test machine, tensile test bench, Vickers hardness tester, 500°C temperature resistance test furnace, eddy current flaw detector and a series of stainless steel products. Testing and inspection equipment to ensure the reliability and stability of the chemical and physical properties of stainless steel products.　

The company annually produces more than 3,000 tons of stainless steel control lines and other products, sales marked covers both domestic and overseas, for domestic, we are network-enterprise company of CNOOC, Petro China and Sinopec, as for international,it has been widely used in Middle East, Southeast Asia, South America, Australia and so on.　

On the premise of improving the quality of its own brand products, the company has continuously increased the research and development of new products, and has cooperated and actively invested with many domestic universities and scientific research institutions. In recent years, the company has passed the certifications of CCS, GL, DNV and other classification societies.
