What kind of pipe is used for heating, good for water heating or electric heating? A floor heating system is a combination of a series of related instruments, you may choose the brand of the wall-hung boiler, the quality of the water separator, but you also care about the quality of the floor heating pipe. Compared with other instruments for floor heating, the most important material for floor heating pipes is the material. There are three kinds of materials you can often see on the market. Part1: What are the materials for the floor heating pipe? Heating pipe identification method PE-RT polyethylene Polyethylene pipe is the most common pipe in the current floor heating market and one of the most widely used pipes. It uses a new generation of floor heating pipe raw materials with superior toughness, stress crack resistance, low temperature impact resistance, outstanding long-term water pressure resistance and Xin Heat resistant creep properties of olefins. In case of accidental damage, it can be repaired by hot melt connection. Usually we think PE-RT polyethylene floor heating pipe is suitable for any heating system below 60 °C. PB polybutene As the name implies, the raw material of PB floor heating pipe is polybutene, which is known as “soft gold†in plastic pipes. PB tube is light in weight, withstand pressure, impact resistance, low temperature resistance and high temperature performance. It can be used for a long time at 100 °C. PB floor heating tube flexibility is the best among all floor heating pipes. It can be used like polyethylene pipe. Fusion and welding, reliable connection. However, due to the relatively high cost of PB pipes, many consumers have stopped looking! PEX cross-linked polyethylene The raw materials for pex pipe production are mainly high-density polyethylene resin. The cross-linking agent is organic peroxide, and the commonly used models are LG, BASF, Borealis and other internationally renowned chemical companies, but PEX The price of floor heating raw materials is quite different. The random selection of raw materials by some domestic manufacturers makes the quality of the products difficult to guarantee, so it is worth noting that this is necessary in the selection and use of floor heating. The purchase of floor heating pipes is also branded. For example, Jinniujiao and American Poly are all well-known brands with reliable quality. If you are not sure, you can choose these brands. Is the quality of the floor heating pipe quality PE pipe good? 1. Look at the surface of the floor heating pipe. The surface of the floor heating pipe with good quality is smooth and not uneven, bubbles, obvious color difference and impurities, and the floor heating pipe indicates the model, specification and brand of the floor heating pipe. The printing on the good floor heating pipe is clear and not easy to fall off. 2, by hand to feel whether the pipe has a groove, the quality of the pipe feels delicate, smooth, moderate hardness. 3. Comparing the flexibility and wall thickness of the floor heating pipe, the wall thickness of the individual heating pipes is marked as 2.0, and some floor heating pipes are marked with a wall thickness of 2.0, but the wall thickness is actually not reached, but the quality of the floor heating pipe is good. The wall thickness is achievable and the same as the label. When you look at the tube and look at it, you may compare it with two types of tubes to see which tube has a thicker wall. 4, to the detection part of the monitoring, to the detection part of the test is the method of suspicion of the floor heating pipe. In some cases, the floor heating pipe used by the floor heating company is a qualified product, and there are test reports and warranty commitments, simple pipe The quality test method may be performed by the naked eye and the hand feeling, but the detection method of the function index can only be performed in the laboratory. Five advantages of PE floor heating pipe 1. Environmental protection: PE-RT and PP-R can be recycled and used without polluting the environment. And PEX can not be recycled to produce secondary pollution; 2, processing performance stability: PEX has the problem of controlling the degree of crosslinking and cross-linking uniformity, processing is complex and processing directly affects the performance of the pipe. The PE-RT and PP-R are easy to process, and the performance of the pipe is basically determined by the raw materials, and the performance is relatively stable; 3, softness: PE-RT is relatively soft. No special tools are required for construction, so the processing cost is relatively low; 4. Thermal conductivity: The floor heating pipe used for the floor needs good thermal conductivity. PE-RT has good thermal conductivity and its thermal conductivity is twice that of PP-R and PP-B pipes. Ideal for floor heating applications; 5, low temperature thermal shock resistance: PE--RT's low temperature impact resistance is better. The pipe is not easily damaged by impact during construction in winter, which increases the flexibility of construction arrangements. Part2: Water floor heating vs electric floor heating method In the past, winter was often used to heat the radiators in the north, while the south was heated by ovens. With the advancement of process technology, the heating method of floor heating has gradually been welcomed by people. What is the floor heating? What are the ways? Let's take a look at the basics of floor heating. 1, floor heating introduction The floor heating is based on the entire ground as a radiator. Through the heat medium in the ground radiation layer, the whole ground is evenly heated, and the ground heat conduction and heat upward radiation are used to conduct the heat from the bottom to the top to achieve the purpose of heating. 2, the type of floor heating Floor heating can be generally divided into water floor heating and electric floor heating. Water floor heating: heating in a heating pipe buried in a filling layer below the ground with hot water at a temperature not higher than 60 ° C, heating the entire floor, and heating the room through the ground by means of radiation and convection heat transfer. the way. Electric floor heating: The heating cable with the upper surface allowed to operate at the upper limit of 65 °C is buried in the floor, the heating cable is used as the heat source to heat the floor, and the temperature controller controls the room temperature or the floor temperature to realize the heating method of the ground radiant heating. There is a big difference between electric heating and plumbing, and there are differences in performance, life and use. The owner needs to decide which floor heating method to choose according to the place where the house is located, the size of the house, and the economic situation. Part3: Heavy construction water floor heating construction method and precautions The general steps of water floor heating construction are: buried casing → residual hole → underground drainage pipe installation → pipe installation → pipe plumbing pipe installation → hydraulic pressure test and water flushing test of each system → completion. 1. Buried casing and reserved holes According to the main image, first underground and then on the ground, first concealed and then set up, first as the main trunk and then branch. Interspersed with various professions to cooperate with each other. Arrange special personnel to reserve various holes according to the main body and construction image. 2. Drainage pipe is buried Before laying the pipeline, first let the line-off worker first determine the laying position of the pipeline according to the coordinates given by the drawings. Then, the excavation should be measured in time when the height is close to the bottom of the pipe. The depth of the bottom of the trench is strictly beyond the elevation. Carry out the tamping and find the slope. 3, direct buried pipeline installation In order to make the pipeline design and quality requirements after installation, the white wire should be pulled first to make the pipeline have a certain slope. The interface is good. It is not allowed to insert the small pipe into the large pipe. After the pipe is installed, water pressure must be carried out before the heat preservation. test. 4, indoor drainage riser installation Before installation, you should study the installation diagram and construction requirements in detail. When the pipe and pipe fittings are opposite, you must first find the pipe fitting angle and then connect it. When connecting, first clean the socket and the socket, and apply the adhesive evenly and then bond.
