Welded 316 stainless steel coil ASTM A249 TP304/304L Bright Annealed
Spezilla offers stainless steel coiled tubing in sizes from 1/4 to 1 in. and wall thickness from 0.035 to 0.049 in. Our coiled tubing is available in lengths up to 2300 feet, which is up to 30% long than traditional offerings. In addition, Spezilla offers less than reel quantities of coiled tubing. Stainless steel tube straighteners make coiled tubing installation faster and easier.
Traceability – All material is fully heat and lot traceable, allowing us to track products from raw material to finished goods.
100% testing for reliability and safer installation - Every foot ofTubing undergoes 100% hydrostatic testing and positive material identification.
