Stainless Steel Capillary Tube Material 825 Specific 1/8"
Feature
The specifications of stainless steel coiled tubing produced by Shaanxi FORUS Petroleum Machinery Equipment Co., Ltd. are as follows:
1. Specification: 1/8″ Material: 825
This product is also known as capillary. It is mainly used for downhole capillary pressure measurement of oil and gas wells, that is, the temperature and pressure sensors (also called downhole precision pressure gauges, generally nitrogen cylinders) and oil and gas well production strings are lowered into the oil and gas layers thousands of meters deep downhole, and then the The 1/8" hydraulic control line (capillary) is connected from the temperature and pressure sensor to the fluorescent screen display on the surface, so that the downhole temperature and pressure can be transmitted to the surface through the capillary, and the fluorescent screen of the surface display can read the oil and gas layer in the well. Instantaneous temperature and pressure, so as to realize real-time monitoring of downhole temperature and pressure. It can also be used for pressure control of surface safety valves and other surface valves, as well as various connection pipelines of large-scale equipment and instrumentation control systems for oil and gas field drilling and oil production.
