In recent years, although house price volatility has been extremely unstable, people who buy houses have continued to go online. The problem with buying a house or a store is the decoration. General warming measures are a major problem in decoration, especially In the northern areas, the warmth of the pipes is really ruining the entire layout, so buying insulation pipes is a top priority. The basic precautions for the construction of polyurethane thermal insulation pipes have always been the focus of attention of many people. The function of the insulation pipe itself is more critical. Whether we are in the chemical, petroleum, aerospace, or central air-conditioning, heating systems, we can see the important performance of such insulation pipe. Here we take a look at the details of the need for attention in the construction of polyurethane insulation pipe .

Polyurethane insulation tube advantages
Polyurethane insulation pipe has become a mature technology in some countries. In recent years, our technical staff has also worked hard to develop this technology. Experimental results show that polyurethane insulation pipe is more suitable for laying. Polyurethane insulation pipe has the following advantages: low cost, low consumption, energy saving, good anti-corrosion performance, long service life, less land occupation, quick construction and so on. Polyurethane insulation pipe is becoming more and more popular with its excellent performance. Polyurethane insulation pipe anti-corrosion and waterproof features make it particularly suitable for insulation and cold insulation projects, it has three layers, namely the working steel layer, polyurethane insulation layer, high density polyethylene protective layer, put on thick clothes, no longer afraid cold.
Polyurethane insulation pipe price
Polyurethane insulation pipe prices to be determined according to the actual situation of customization, all localities should have insulation materials manufacturers, purchase directly to the manufacturers to ask on it, or find the phone online, we must choose the best reputation, price concessions Big manufacturers can shop around.
Polyurethane insulation pipe manufacturers
Tangshan Kaixiang Insulation Material Manufacturing Co., Ltd.
The company is younger than other brand companies, but its development potential is very good. Up to now, it has a one-third degree of sales of similar products in North China, and its production has also expanded to overseas, and its insulation pipe Variety is also gradually increasing, compared to the current insulation pipe industry is relatively rich, and polyurethane insulation pipe is a very good reputation. The contact information is 03152318000.
Luzhou Chengyuan Pipeline Co., Ltd.
The company’s prices are relatively more favorable than comparable brands. The main reason for this is that its corporate headquarters is located in the Yanshan County Industrial Development Zone in Hebei Province. This is where China’s pipeline production base is located, and it is very close to the raw material region, so its price Will be a little more favorable than the same brand. Of course, there is another reason why the change of the company's main concept is the concept of the customer first. The service is super good. Basically, it is a repeat customer and customer driven sales. It is also sold overseas. The contact information is 03178212877.
Changsha City Guangheng Building Material Co., Ltd.
When you listen to the name, you know that this company is mainly engaged in construction, and it is not specialized in piping. However, the main reason why Xiaobian recommended him here is because it is mainly made of buildings. Why is it? Because it has a special design for making medicines and building buildings, and pays more attention to the overall appearance, so even though its pipeline is not a major project, compared to other companies that specialize in pipelines, it is home to The pipeline is beautiful, and the company was established in 2005. It has been 10 years since. Although this is not a long time for a company, it is a decade for the industry. Its contact number is 07318205057.
Guangzhou Jiji Energy Storage Technology Development Co., Ltd.
The company was founded earlier than the previous company. In 2002, although the company’s headquarters was in a warm coastal area, it must not be questioned that its technology was inferior to that of a company with the same brand name. This company has been With quality and technology as the mainstay, the quality is super-safe. We have also done a project to keep the village warm and have achieved a good social assessment. The contact method is 400691250.
Polyurethane insulation pipe construction project should pay attention to the details
First, the staff must carry out careful and careful inspection after entering the site. It is very important for the relevant inspection procedures before construction. Any unqualified equipment, insulation pipes, and raw materials are rejected.
Secondly, in the process of conducting the welding of polyurethane insulation pipes, it is also the key to the quality of the entire project. Therefore, we must pay more attention to the fixation of the brackets and the welding of pipes. To know that these two steps directly affect the quality and effectiveness of the entire insulation project in the later period, it also directly determines the service life of the entire pipeline.
Third, under the pressure of meeting the pressure, it should pay attention to the pressure of the pipeline. This step should be divided into two steps. First, there is no leakage inside the regulator and the pressure can be increased. Then use a small hammer that meets the standard weight to perform a percussion inspection around the weld to see if there is a leak. Finally, the pressure inside the polyurethane insulation pipe was adjusted to the working pressure range. If no leakage occurred within about half an hour, it was even passed.
Fourth, it must be known that such polyurethane insulation pipe construction is directly laid underground, and such works are usually hidden works. If during the construction or inspection process, there is no meticulous care or acceptance is not careful, then in the future use of the operation process, there may be frequent failure or other phenomena. Even after the completion of the construction of the polyurethane insulation pipe, relevant units are required to send special personnel to carry out strict and serious inspections.
Fifth, no matter which type of polyurethane insulation pipe construction method is chosen, attention should be paid to the quality of the pipeline and the situation of cracking and delamination. The most important thing is to ensure that the joints of the pipeline have the required waterproofness, tightness and integrity.
Editor's summary: Polyurethane rigid foam insulation material for the construction industry is an important branch of the polyurethane industry. It is characterized by a multi-purpose, and at the same time with insulation, waterproof and other functions. This type of product has been used for 40 years since its application in the European construction industry in the 1960s. Some countries have also passed legislation to use polyurethane as the insulation material for waterproofing specified by the construction industry. In recent years, with the rapid development of China's building energy-saving market, polyurethane rigid foam body insulation products have been widely used in the field of building insulation and waterproofing, and have become one of the leading insulation and energy-saving products in the market.
