Frequently Asked Questions (FAQ)

What grades of stainless steel coiled tubing do you offer?

We provide a wide variety of grades including Common Grades (TP304, TP304L, TP316L, 904L, etc.), Russian standards (08X18H10, etc.), German standards (1.4301, 1.4404, etc.), Japanese standards (SUS304, SUS316L, etc.), Double-Grades, and Super Duplex Steel (2205, 2304, S31803, S32750), alongside High Nickel alloys like Monel400, Inconel 625, and Inconel 825.

What is the typical unit length of the coiled tubing?

We can manufacture seamless control lines with lengths of at least 8,000 to 10,000 feet per coil. Custom lengths can also be tailored to meet your specific application requirements.

What are the pressure ratings and size ranges for these tubes?

Our standard size range covers outer diameters (OD) from 1.5 mm to 15 mm (including 1/8", 1/4", 3/8", and 1/2" options). Depending on the wall thickness and size, they are rated to withstand working pressures from 70 Mpa up to 100 Mpa.

What surface treatment options are available for the capillary tubes?

Our tubes come with a bright annealed finish. They are polished soft on both the inner and outer surfaces to maintain high cleanliness for fluid control systems.

What are the main applications of these control lines?

These coiled tubes are widely used in medical acupuncture, high-pressure instrumentation, coal exploration, thermostats, beer brewing equipment, drinking water systems, and refrigeration systems using Danfoss expansion valves.

What is the Minimum Order Quantity (MOQ) for coiled control lines?

The minimum order quantity for our production runs of stainless steel coiled tubing is 500 kilograms per specification.
