Description

Boiler distribution pipe manufacturing method and distribution pipe produced by the manufacturing method {Boiler distribution pipe manufacturing method and distribution pipe produced by the manufacturing method}

The present invention relates to a distribution pipe for a boiler, and more particularly, to a supply pipe for supplying hot water, a distribution pipe for distributing and transferring the supplied hot water to an indoor space, and a return pipe for circulating and transferring the distributed hot water to the boiler. In the piping system for a boiler made, the manufacturing work of the distribution piping can be carried out in a systematic and stable manner by dedicated process facilities built step by step, and the structure of the distribution piping to be manufactured is improved to detach and combine with the distribution piping. It relates to a method for manufacturing a boiler distribution pipe to facilitate individual connection of distribution hoses and a distribution pipe produced by the manufacturing method.

In general, a boiler refers to a system facility that generates high-temperature hot water by heating water or fruit by fire, combustion gas, or electrical heat, and circulates and supplies the generated hot water to an indoor living space to perform a heating function.

Such a boiler is largely composed of a boiler body for generating and supplying hot water by a heat energy source, and a distribution device for receiving hot water from the boiler body and distributing and delivering the hot water to each partitioned indoor space to perform a heating action.

In addition, the distribution device serves to supply hot water supplied from the boiler body to a plurality of indoor spaces partitioned by use, for example, a room, a living room, a kitchen, etc. The distribution device supplies hot water from the boiler body. It consists of a supply pipe for supplying hot water, a distribution pipe for distributing and delivering the supplied hot water to each partitioned indoor space by opening and closing the valve, and a return pipe for returning the hot water exchanged through the distribution circulation process to the boiler again.

On the other hand, in the various piping configurations formed by the distribution device, the distribution piping is an intermediate medium connecting the supply piping and the return piping, and plays a role of evenly distributing the supplied hot water to the partitioned indoor space, resulting in relatively high precision and Watertightness and durability are required.
