Product Commitment Chapter VI Feasibility of Polyethylene Pipeline;
1. Compared with metal pipes, it is environmentally friendly and healthy, and has a long service life;
Second, in urban construction, water supply, underground gas transmission and other fields, plastic pipes will replace metal pipes with their excellent performance;
Thirdly, the company conforms to the trend of the times and tries its best to introduce polyethylene PE pipes, random polypropylene PP-R pipes, polyethylene double-walled corrugated pipes and polypropylene double-walled corrugated pipes. At the same time, the company develops and produces all kinds of injection-molded fittings, electrofusion fittings and welded fittings to ensure the safe operation of the pipeline system. The pipeline system of XXX company has been widely used in municipal water supply, building life (cold and hot) water supply, underground gas transmission and distribution, drainage, floor heating, agricultural irrigation, telecommunications, environmental protection, chemical industry and other fields;
4. Long service life. Under the rated temperature and pressure, the pipeline can be safely used for more than 50 years.
5. The sanitary performance is good, no toxic additives are added in the pipeline production process, and the inner wall of the pipeline is smooth, without scaling and breeding bacteria;
6. Good chemical stability and corrosion resistance to various acids, alkalis and salts;
Seven, the impact resistance is good, which is five times that of PVC pipe;
Eight, good toughness, deformation resistance and earthquake resistance;
Nine, the low temperature resistance is good, and the low temperature brittle temperature can reach-70℃;
Ten, reliable connection performance, welding strength is consistent with the strength of the pipeline itself;
Eleven, light weight, the specific gravity is only 1/8 of galvanized pipe, convenient construction, safe and time-saving;
12. The thermal insulation performance is good, and the thermal conductivity is only1150 of that of galvanized steel pipe;
Thirteen. The random polypropylene PP-R pipe can withstand high temperature and can be used.
Used for conveying hot water; 14.PE80 and PE 100 have good environmental stress cracking resistance and excellent rapid cracking ability; Fifteen, polyethylene pipe has ten advantages:
1, coil, generally less than? 160mm can be made into a coil, which reduces the connection;
2, after the surface welding, and then laid into the groove;
3. Butt welding connection between pipes saves fittings and is firm and reliable;
4, trenchless technology can be used, such as directional drilling and laying, laying the letter pipe without destroying the ground and the existing pipeline;
5. Repairing old pipelines by pipeline method will be widely used in the reconstruction of aging urban pipe network. One is to drag the connected polyethylene pipe directly into the old pipe, and the other is to squeeze the polyethylene pipe into a smaller diameter and drag it into the old pipe, and then introduce steam to restore the original diameter and cling to the old pipe wall;
6. Laying polyethylene pipes at the bottom of rivers, lakes and oceans by underwater method;
7. Pipe fittings with diameter (≥90mm) can be made of welded pipes, which reduces the cost of pipe fittings;
8. Construction can be carried out in low temperature environment in winter;
9. The requirements for ground excavation are not high, and the ditch is narrow and shallow, which saves labor and effort. Trencher goes first, and then pipes are laid.
10. Practice at home and abroad proves that polyethylene pipeline has the best seismic performance and safety.
Solution of thermal expansion and cold contraction of polyethylene pipeline;
Polyethylene pipe has the characteristics of thermal expansion and cold contraction, which is harmless to polyethylene pipe itself, but harmful to some pipeline accessories.
Or the cast iron pipe of the socket is easy to shift or fall off. Generally speaking, the way to solve the negative effects caused by thermal expansion and cold contraction of polyethylene pipes is to reduce the temperature change around the polyethylene pipes and fix some parts of the polyethylene pipes.
1, large-diameter polyethylene pipes are mostly used for burying, which can effectively prevent thermal expansion and cold contraction after burying. And make concrete piers in key parts (such as elbows, tees and places where pipe fittings need to be fixed, etc.). );
2. If there is no underground condition, polyethylene pipes must be laid in the open air, and thermal insulation materials and ultraviolet protection layers should be wrapped around the polyethylene pipes. Try to maintain the serpentine laying of the pipeline, and make concrete piers at key parts (such as elbows, tees, places where fittings need to be fixed, etc.). )
3. When the indoor polyethylene pipe is used as a concealed pipe, it can prevent thermal expansion and cold contraction because it is buried in the wall. As an open pipe, a certain number of pipe clamps can be reserved to prevent thermal expansion and cold contraction.
Connection method of pipe fittings for quick emergency repair;
(a) small diameter PE pipeline (≤? 63) The damage is completely repaired.
1, direct header. Due to the good flexibility of small-diameter PE pipes, damaged pipes or fittings can be replaced by socket connection as long as there is a certain space for telescopic swing.
2. Fuse the bushing. In some fixed places, you can't swing telescopically, and you can use fused sleeves instead of pipes or pipe fittings.
(2) Large diameter PE pipeline (? 63) The above damages have been completely repaired.
1, fuse the saddle plug. Suitable for repair? 90≤d≤? 3 15 PE pipeline is pierced with a small hole or hole. (Fused connection)
2. Use 1 fused bushing. Suitable for repair? 90≤d≤? When the pe pipe joint of 3 15 leaks or a section of PE pipe needs to be replaced, a certain length is needed for fixing. (When hot-melt butt joint is used, electric-melt butt joint is used)
3. Use 2 electrofusion sleeves. Suitable for repair? 90≤d≤? 3 15 PE pipe joint leaks.
Or when a section of PE pipe needs to be replaced, it can be used in a place where both ends are fixed. (Fused connection)
4. Use two sets of PE flanges. Suitable for repair? When more than 90% of pe pipe joints leak or a section of PE pipe needs to be replaced, a certain length is needed, which is suitable for the situation that one end of the damaged pipe has been fixed. (Hot-melt butt joint)
5. Use 4 sets of PE flanges. Suitable for repair? More than 90% of pe pipe joints are leaking or a section of PE pipe needs to be replaced, which can be used wherever both ends are fixed. (Hot-melt butt joint)
Connection measures of polyethylene pipes with valves and fire hydrants (including above ground and underground): PE pipes are connected with valves and fire hydrants by flanges. PE flange includes flange root and flange, the flange root is PE with waterline, and the flange is plastic steel flange, which can be connected with steel flange.
PE pipes connect valves and fire hydrants, and steel pipes connect valves and fire hydrants in the same way, but the flange materials are different. For example, clean the flange, align the flange, pay attention to the position of the gasket, and press the bolt evenly.
When PE pipes are connected with valves and fire hydrants, attention should be paid to thermal expansion and cold contraction, and piers should be added to key parts. Necessary installation measures should be taken for the pipeline of reclaimed water spray system;
The necessary installation measures for the pipes of reclaimed water spray system are the same as those for ordinary polyethylene pipes. The pressure of reclaimed water spray pipeline is slightly higher, and the pipeline wall thickness is thicker. In the process of installation and welding, it should be noted that the welding time is longer than that of ordinary polyethylene pipes.
