It is considered a high quality tube, and is normally constructed from SAE 1020 or 1026 steel. Note that, technically DOM refers to the process by which the tube is finished after having started as an ERW tube. Technically, DOM is not a type of steel tube, but rather a process. As so often happen though - in common use the term has become accepted to mean a specific type of tubing rather than a process.
Capillary tubes. Air Conditioning capillary tubes do the same as the txv except for one major difference. A cap tube cannot adjust for superheat. A capillary tube is a very small tube or usually multiple tubes that refrigerant is forced through.As the refrigerant moves from a large tube and into a very narrow, small tube it obviously has a major drop in pressure.he metering device is located after the condenser coil. There are two kinds of metering devices, thermal expansion valves (TXV) and capillary tubes. Either one does the same thing; they lower the high-pressure liquid pressure by forcing it through a small hole or nozzle.
