Installation specifications for electrofusion fittings

According to the previous detailed introduction, I firmly believe that you for pe electrofusion pipe fittings should get the corresponding mastery, because the electrofusion pipe fittings manufacturers of pipe fittings with good characteristics, so in many areas of the industry to achieve the process of transport of goods will be the choice of the commodity, we will understand is not the characteristics of the commodity and its characteristics are good, in the realization of the choice of the process is not prone to produce the situation must be in accordance with the appropriate operating procedures to achieve the choice can give full play to the relative effectiveness of the choice. Appropriate operating procedures to achieve the selection can give full play to the corresponding selection of efficacy, in addition to the appropriate in accordance with the actual operation, but also need to master the following installation and use of standards:

1, in the articulation of curved bullet electrofusion fittings before the pipe fittings, pipes and pipelines near the realization of verification, in accordance with the provisions of the design programme, and in the construction of the project to achieve the appearance of the design and product quality inspection, in line with the provisions of the provisions of the provisions of the selection can be made.

2, usually pipe fittings, pipe fittings and piping near the selection of hot melt connection or mechanical connection, when the nominal diameter of the pipe diameter is higher than or equal to 110 mm can not be selected manual hot melt hot melt connection for polyethylene pipes and fittings can not be selected flange connection.

3, polyethylene pipe if belongs to different SDR pressure level series products, can not choose hot melt connection. Pipes and metal pipes or metal pipes near the connection, should use flange or steel-plastic transition joints to achieve the connection.

4, the pipeline to achieve articulation to choose a special type of articulation of special tools, prohibit the electrofusion fittings to achieve open-flame heating.

5, fittings and piping connection should be selected with the same grade level and the same pressure level, different grades of fittings and piping to achieve the connection, should be tested first, after determining the quality of the product can be guaranteed, to achieve the connection.

6, the choice of steel spray or ductile iron transition fittings, transition fittings pressure level can not be lower than the nominal pressure of the fittings.

7, the realisation of electrofusion fittings hot melt connection operation, if in cold weather or windy conditions, there should be protective measures.

8, fittings should be cut with a special type of cutting special tools, cutting section provisions flat, smooth, burr-free, and perpendicular to the pipe axis. After the pipe connection, should check the appearance of the joint design product quality in a timely manner, such as unqualified check, must rework until qualified.

According to the specific content of the above details, we can see that in order to give full play to the corresponding selection of electrofusion fittings, in addition to the proper installation operation in accordance with the realization of the other, but also need to pay more attention to the above installation and use of the standard, so that the fittings in the process of selection is not prone to produce the situation in the process of selection of the process of selection of fittings need to be achieved in a timely manner to achieve the inspection and its pipeline to improve the corrosion resistance work! Tasks, so that the pipe fittings are not easy due to some external factors affect the normal selection of efficacy.
