Copper pipe GOST 21646

Copper pipe GOST 21646

The use of copper and its alloys for the manufacture of pipes began in the 19th century. All the advantages of this unique material is available: a high thermal conductivity levels, excellent durability, copper is not oxidized and does not form rust, allowing the internal surface of the pipes do not become clogged and do not corrode even when exposed to highly corrosive environments. That is why the copper pipe gets its widely used in various fields.
The pipe is used in complex heat exchangers. Modern copper pipe withstands high temperature and hydraulic load, ensuring correct operation of the heat exchangers. For standardization and quality control of copper pipe is made in strict accordance with GOST 21646. Increased requirements for strength and other parameters of the pipes due to their specific application, which ensures safe operation of complex and expensive equipment in the future. For copper pipe must withstand maximum loads without breaks, bruises and cracks, tensile residual stresses have not, it must not break during flattening. To meet all the requirements of the limits of allowable loads, the copper pipe is thoroughly tested by hydraulic pressure, flattening deformation, load at break, etc. Monitors for the presence of internal and external defects. Cracks, voids, etc. Strict chemical composition of copper and brass alloys in the manufacture of pipes as per GOST 21646 provides a full set of distinctive strength and plastic-deformation properties inherent in these products. And only passed all the required tests, copper pipe reaches the consumer.
