1 / 2 * 0.065 ASTM B704 Alloy 625 Capillary Coiled Control Line Tubing Oil & Gas
We have been focusing on the production and sales of stainless steel control pipe capillaries for many years, which have accumulated rich experience and technical strength, and are famous for variety, complete specifications and good quality.
For Capillary tubes with a maximum bore of 0.0158 in., available in a wide range of stainless steels, our capillary tubes are featured by tight tolerances, and the inside surface of the tubes is free from oil, grease and other particles. This ensures, for example, an optimized and even flow of liquids and gases from the sensor to the measuring instrument.
Our control lines are selling well and widely used by customers especially in Indonesia, Oman, India, Russia, UK and Pakistan markets, etc. With superior quality and competitive price, we can guarantee 100% pass rate and delivery rate.
