Construction instructions

Lay in parallel and try to go in a straight line

Fittings and valves of parallel pipelines are staggered

Welding and threaded connections with appropriate flanges and live pipe joints

Pipes should be installed along the walls of the factory building where possible, and the distance between pipes and walls should be able to accommodate live pipe joints and flanges.

The height is convenient for maintenance, with sidewalks >2m, crossings >4.5m, and rails >6m. The elevation of the main trunk line passing through the factory is 5m

The weld should not be located within the bracket, and the distance from the bracket should not be less than the pipe diameter

When passing through the wall, add a casing to the pipe and fill the gap with filler

Centralized laying

Avoid welding seams when passing through walls and floors

General valve 1.2m, safety valve 2.2m, thermometer 1.5m, pressure gauge 1.6m

slope

Separate hot and cold fluid pipes

Avoid passing over motors and distribution boards

Water pipes and wastewater pipes are buried underground, below the frozen soil layer

Ball valve for vacuum pipeline

Compressed air: air compressor room; vacuum: vacuum pump in this workshop

For long-distance real air pipelines, a drain trap should be installed at a certain distance to remove condensed water.

Ceramic pipe buried below 0.5m
