Converging pipe refers to the part of uniform air supply converging pipe in the whole ventilation system. The area of air duct shall be calculated by the average perimeter, and the corresponding specification subitem shall be applied. Its labor shall be multiplied by a factor of 2.5, and the rest of the equal diameter pipe shall be calculated as ordinary air duct.
Ductile iron converging pipe is one of the ductile iron pipe fittings, also known as double bearing converging pipe. The pattern is that both sides of the short pipe are sockets. Double bearing converging pipe belongs to T-joint spherical graphite fittings, which is used to adjust the diameter of straight pipe or pipeline to meet the needs of pipe network. Double bearing converging pipe can be customized according to the needs of engineering installation.
Ductile iron converging pipe is a common pipe fitting in water supply network, which is mainly used to adjust the pipe diameter. In municipal water supply network, double bearing converging pipe is a common pipe fitting.
Standard: GB / ANSI /JIS / DIN
Application: gas and oil pipes
Pressure: 1.25Mpa
The caliber range is different. The diameter range of reducer is relatively wide, and the current standard is from dn15-dn3400 (1 / 2 "~ 136"). And the specification range of converging pipe is: dn6-dn300 (1 / 4 "- 12") is generally the maximum DN100.
Raw material difference. The reducer adopts seamless steel pipe or steel plate, seamless product is steel pipe, and seamed product is steel plate. The converging pipe is made of round steel or billet.
Production process difference. The production process of reducer is as follows: seamless products are hot pressed or cold pressed (heat treatment is required for cold pressing) and seamed products are hot rolled. The production process of converging pipe is forging process.
Because the ductile iron converging pipe adopts flexible joint, the construction operation is more convenient.It can improve the construction efficiency, improve the construction conditions and reduce the construction cost. Moreover, most of the joints are connected by rubber ring.
It is easy to operate, can shorten the construction period and reduce the construction cost.The ductile iron converging pipe has the advantages of high water supply pressure, resistance to external load and adaptability to geological conditions. The pipe has the advantages of high strength, good toughness, corrosion resistance, convenient installation of flexible interface, strong seismic resistance and low labor intensity.
The ductile iron converging pipe has good sealing performance and is not easy to leak.It can reduce the leakage rate of the pipe network and the daily maintenance cost of the pipe network.
