Pipe welding specification

  1. If it is standard, please download gb50236-2011 "site equipment, industrial pipe welding engineering construction specifications" from baidu or standard website.

2. The first chapter reads the pipeline construction drawings1. The design specification requires that the heating branch pipe shall not be less than DN20.2. General practice of heat preservation -- water supply: anti-condensation heat preservation, hot water: heat preservation, fire protection: no heat preservation, frozen water: even the valve needs heat preservation, cooling water: according to the design requirements, not required.The pipeline in general condole top all needs heat preservation.Water supply: dark application prevent condensation insulation;Ming fu through the entrance hall, bedroom and living room must do anti condensation insulation.Drainage: dark apply to prevent condensation insulation;The toilet seat must be open to the public.In addition to fire, spray pipe pipe pipe insulation.

3. Galvanized steel pipe connection: DN100 wire connection, >DN100 welding (anticorrosive), flange welding (secondary galvanized), a small number of screw flange connection.

4. The distance between the pipe skin and the wall is 25-50mm.

5. When the heating and drying pipe is connected with the riser, when the vertical pipe segment of the riser is less than 15m, two 90’s are adopted.Elbow, 3 90 for straight pipe >15m.Elbow.

6. During construction, the drainage pipe should be higher rather than lower, and the floor drain should be lower rather than higher.

7. Elevation regulation: indoor pipe is generally in the pipe, outdoor pipe drainage is in the bottom of the pipe, and water supply is in the top of the pipe.

8. The radiator should be coaxial with the window.

9. Gate valve: switch action, resistance coefficient 0.5;Globe valve: adjusting switch function, resistance coefficient 19.

10. The compensator is divided into: natural compensation, square expansion force, elbow, corrugated compensator, sleeve compensator, spherical expansion force, horny expansion force
