Seamless Coil Tube
Specific Applications
▪ Single Transmission
▪ Monitoring and Control Equipment
▪ Injection Line
▪ Down-Hole Safety Valve Control Our coiled seamless tubing is available in a number of high performance corrosion resistant stainless steel and high nickel alloys, including the 300 series Monel, Inconel, and Hastelloy, capable of withstanding a variety of severe environmental conditions.
We specialize in manufacturing small diameter tubing ranging and variety of wall thicknesses. We can supply coiled seamless tubing in loose bulk wound coils, or level wound on various size reels.
Seamless Control line tubing
Our Seamless control line tubing is drawn from seamless extruded tube hollows supplied by leading primary manufacturers to ensure absolute product safety and reliability. Our seamless control line tubing is one continuous length of tubing, completely free of any welded joints or seams. Long length coils reduce installation time and costs by eliminating the need for excessive joint preparation and fittings. Elimination of excessive fittings increases reliability and assures a leak-free system. We are capable of 100% hydro-testing each coil.
● Corrosion Resistant Material Selection
| Alloy | PREN | Density | Application Alloy | |
|---|---|---|---|---|
| g/㎤ | lb/㎤ | |||
| 304 | 21 | 7.93 | 0.29 | General good corrosion resistance grade |
| 304L | 21 | 7.93 | 0.29 | Lower carbon than 304 impedes carbide precipitates in heat affected zone giving good weld ability. Reduced carbides also lowers susceptibility to intergranular corrosion |
| 316 | 24 | 7.98 | 0.29 | Alloyed with molybdenum which improves corrosion resistance in marine environments, chlorides, and biofouling. Excellent pitting corrosion resistance. |
| 316L | 24 | 7.98 | 0.29 | Carbon content restricted, which impedes carbide precipitates in heat affected zone giving good weld ability. Reduced carbides also lowers susceptibility to intergranular corrosion |
