Copper capillary pipes Group A

Copper capillary pipes Group A

What is Copper capillary pipe? Yes, a pipe made of copper, but has usually a very small inner diameter. Hence the name "capillary". Industry produces copper capillary tube groups A and B. In this article we will be considered a tube of A. copper capillary tube is manufactured in accordance with GOST 2624. Outside the diameter ranges from 1.2 to 2.5 mm in accordance with GOST. Implemented in coils, wherein the length of tubing, the wall thickness is less than 0.4 mm, should be at least 10 meters (100 meters for tubes having a wall thickness greater than 0.4 mm). The ends of the tubes must be flattened before full contact of the wall for a length of 10 mm to 15 mm. The series, which is wound around the tube should be correct and does not hinder unwinding. Symbols for the tubes consist of: manufacturing method, such as sectional, precision production, condition, size, brand, and GOST. For example: The handset FKRHT 2,10h0,85h9000MD M2 2624-77. Copper capillary tube is made from copper grades M1r, M2P, M2, M3, group A tube may be made of brass L96. Copper capillary tube is used in areas such as refrigeration systems, chemical industry, power generation, shipbuilding, instrument. Pipes Group A recommended use for general purposes, for example, for the manufacture of measuring instruments. They can be used in environments such as air, fuel, oil, etc. Pipes Group B are recommended for use in refrigeration equipment as chokes between the evaporator and the condenser. They are used in refrigerants environment. Copper pipe is resistant to many corrosive influences, has excellent thermal conductivity, is relatively cheap and does not require any additional regulation, and therefore, is widely used in all of these areas.
