Strengthened calibrator for big size is one of the key tools for installing Aluminum-plastic pipes. As an innovative manufacturer of high-performance plumbing products, Zhuji Primy Pipe Co., Ltd. Offers a full line of Aluminum-plastic pipes and fittings crafted to deliver strength, ease of use and an attractive appearance.
(1) Method for color identification of aluminum-plastic tubes
The color identification of aluminum-plastic pipes is usually carried out by means of labels or belts. The label is marked with the material, model and color information of the aluminum-plastic pipe, which is easy to identify and manage; The ring belt is to put different colors on the pipe to distinguish different types and uses of the pipe.
(2) The meaning of aluminum plastic pipe color
Different colors of aluminum-plastic tubes represent different meanings and uses. The following are several common aluminum-plastic pipe colors and what they represent:
Yellow: represents gas pipelines, such as gas, liquefied gas, etc.
Blue: represents the water pipeline.
Green: Sewers and sewage pipes.
Purple: represents the high-voltage transmission cable protection pipe, usually used in the main road and central square of the city.
Orange: represents telecommunications pipelines, such as telephone, broadband, TV lines, etc.
Gray: represents industrial pipelines, such as chemical, petrochemical, etc.
Red: white, black and other colors: represent other uses.
Strength test pressure of aluminum-plastic pipeline after completion of construction.
1. Test the pressure:
When the working pressure is less than 1.0MPa, the strength test pressure of the aluminum-plastic pipe is 1.5 times the working pressure, but not less than 0.9MPa.
When the working pressure is > 1.0MPa, the strength test pressure of the aluminum-plastic pipe is the working pressure plus 0.5MPa.
2. Operation procedure:
(1) The pressure gauge should be installed at the lowest point of the aluminum-plastic pipe system, and the pressure pump should be located near the pressure gauge.
The pressure gauge for the strength test of the aluminum-plastic pipeline must be installed at the lowest point of the aluminum-plastic pipeline system, and the pressure pump should be located near the pressure gauge
(2) Fill the aluminum-plastic pipe with water and completely drain the air in the pipe.
(3) Use the pressure pump to increase the pressure to the test pressure, and then re-pressure to the test pressure every 10 minutes, repeat twice.
(4) Record the pressure at 10 minutes and 40 minutes after the last pump pressure, and the pressure difference between the two must be less than 0.06MPa.
