Introduction

Pipe external diameter not exceeding 108 mm are suitable for capillary brazing, including brazing, or bonding them by mechanical deformation.

Connection pipe outer diameter 108 mm, more preferably soldered by hard solder or welding.

1 Scope

This standard applies to seamless copper tubes of circular cross section used in drinking water systems, hot and cold water, water (steam) heating, cooling, sewage, water treatment plants and gas supply. This standard is also used for pipes for pre-insulation.

The standard specifies the dimensions, technical requirements, acceptance rules, methods of control and testing, marking, packaging, transportation and storage of pipes.
