Copper water pipe is a kind of copper pipe, drawn from high-quality copper. Copper pipes and fittings are the best choice for water supply, gas supply and heating piping systems. They can be widely used in building cold and hot water supply and drainage, direct drinking water, and Water, gas, medical, food, chemical and other fields. What are the advantages of copper pipes? What is the installation procedure for copper water pipes ? Today I will explain the relevant knowledge of copper pipes for everyone. If you are interested in it, you may wish to follow me to learn about the installation of copper pipes and copper pipes .
Copper water pipe introduction
The inner wall of the copper pipe is smooth, long-term use will not rust, scaling, can avoid secondary pollution of water, reduce head loss, reduce heat loss, can inhibit the growth of bacteria in the pipeline, has a stronger advantage than other traditional water pipes.
Copper pipe advantages
1. Durable
Copper is a hard, hard metal that resists corrosion. Can be used in a variety of environments without damage. From the perspective of the history of the use of foreign countries, the use of many pipelines has exceeded the service life of the buildings themselves. The copper life of the Beijing Union Medical College Hospital has reached 80 years, and is still in use. After the brass pressure test is put into use, it will not leak or break, and it needs no maintenance for almost a lifetime.
2. Health and health
Copper can be said to be a "red metal with a green face." Copper can inhibit bacterial growth and keep drinking water clean. Cooking tea with copper kettle is a method of ancient health care.
3 high temperature, high pressure
Copper pipes and fittings can maintain their shape and strength under high temperature and high pressure, and there will be no long-term aging.
Copper water pipe standard
First, the application of the national standard is relatively narrow, and most manufacturers still produce according to the European or American standard system, which facilitates market support.
Secondly, because the US standard system requires the highest tolerance and the highest production cost, the market can have only a few supply sources.
Third, the so-called European standard pipe fittings in China do not actually meet the standard requirement of 100%, which is mainly reflected in the matching of materials and tolerances.
Household copper plumbing installation process
1. Drawing conversion and construction drawing design:
(1) On-site measurement, draw a single line diagram of the pipeline.
(2) Determine the shape, number, and location of the compensation device.
(3) Determine the form, number, and location of the support and hanger.
(4) Determine the type of insulation material and its construction method.
2, cutting, forming and prefabrication
(1) According to the single-line figure cutting.
(2) Bend bend shape.
(3) Processing prefabrication of "Ω" expansion joints.
(4) Prefabrication of support and hangers.
(5) Prefabrication of pipe sections.
3, the laying of the pipeline
(1) According to the pipeline to lay the pipe support, hanger.
(2) Laying pipes and connecting them.
Two simple and convenient ways of installing copper tubes: snap-on connections and welding.
The card-type connection originated in England in this century and is ideal for home installations. Its greatest strength lies in its safety, economy, cleanliness, speed and ability to withstand sufficient pressure. This method is mechanically linked by compressing the seal or pressure ring on the tube. Choosing to use the card-type connection is accomplished using the simplest tools such as a wrench. If leakage occurs after installation and it is easy to repair, just tighten the nuts directly without draining the water and disassembling the water pipes. The price of copper pipes is also different due to the increase in copper prices.
Another type of installation is soldering, which is subdivided into soldering and brazing. The main difference between the two is that different metal fillers are used. Both welds are heated at the joints, dissolved by adding solder, and the dissolved solder is sucked into the joints.
Both welding should pay attention to the following steps:
1. Accurately measure copper tubes and cut copper tubes;
2. Remove burrs and clean the surface;
3, use the right amount of solder;
4. Heat the copper tube and use the proper amount of solder;
5. Allow the connector to cool and remove excess solder.
