Overview
Stainless steel capillary tube is widely used in automobile, aerospace, medical industry, instrument, line protection and the like. In most cases, they are delivered in straight form, 6 meters typically or customized. Even for long length purpose like line protection, it goes around several hundred meters per coil.
However, for petroleum industry, stainless steel capillary tubes are always delivered in coiled shape and the length can go up to 15000 meters for one single coil. This article will walk you through stainless steel coiled tube applied specifically in oil and gas industry.
Coiled Stainless Steel Capillary Tube
Stainless steel coiled tubing, or stainless steel hydraulic control line is the coiled stainless steel capillary tube applied in petroleum industry. Due to the harsh working condition, the supplied coiled tube is required to withstand high temperature and high pressure with extreme length such as 15000 meters one single coil. TP316L is the most popular choice, but not limited to this.
