PB地暖管

产品介绍

PB地暖管以聚丁烯合成高分子综合而成,含有特殊密度(0.937)结晶体,是一种先进的地暖管材料,耐高温、强度高。在生产时不含任何添加剂,可适用于任何地暖、热水管道系统中。PB管诞生于二十世纪70年代,是目前科技含量较高的化学材料之一,被誉为塑料中的软黄金。在几种地暖管材中比较柔软,相同的设计压力下设计计算壁厚比较薄。在同样的使用条件下,相同的壁厚系列的管材,该品种的使用安全性高。但原料价格高,是其它品种的—倍以上,当前在国内应用面积较少,欧美发达国家已被广泛采用,并取代铜管成为冷、热水给水管道的选择,未来市场会慢慢的普及这种管材。

产品执行标准

CJ/T372-2011冷热水用无规共聚聚丁烯管材及管件

产品特点

特点关键词;高分子材料、不结垢、耐温、抗冲击、柔韧性、施工方便

1、高分子材料品质可靠∶以PB树脂为原料,由干聚工烯(PB)比其他类树脂聚合程度更高,分子量更大,分子结构更稳定,因而具有更

强的耐热蠕变性和抗应力开裂性,具有更长的使用寿命。

2、不结垢∶不结垢是塑料管材的共同优点,除此之外PB管材可耐大多数无机溶剂,室温下可耐绝大多数酸、碱、盐溶液及各种化学药品等,金属管和其他塑料管无可比拟。

3、耐高温和低温∶优质的PB地暖管材可以在-20℃~25℃下不被冻裂还可以进行弯曲施工同时还可以在100℃的热水中保持物理化学性能不变。

4、抗冲击∶由于PB管材具有很好的柔韧性,使得管材的弯曲半径很小,吸收水锤和外部冲击的能刀很强,管道不容易意外破坏.

5、柔韧性抗温度应变力极佳∶PB地暖管的热膨胀系数相对牧小,而柔韧性却很高,施工时极易弯曲。对干弯曲半径不是特别小的地方,完全可以不使用管件连接,而且由于抗温度应变能力强,也可以不用过多考虑热膨胀的补偿问题。

6、施工方便易于维修∶多种连接方式,可满足个同设计和施工安求.出现人为损坏时,可热熔连接,易于维修,安全可靠。

产品用途

1、地板采暖、水地暖等低温采暖系统及空调用管道系统。

2、采暖用管材∶可用于连接暖气片等高温采暖系统。

3、自来水的冷热水管∶直饮水工程用管。太阳能住宅温水管∶用于太阳能住宅的温水和取暖配管。

4、熔雪用管∶适用于公路、停车场下面作为除冰雪用加热配管。

5、工业用管∶因材料耐化学腐蚀性强,无毒无味,可用作化学工程、食品加工和工业用水等领域。

运输安装

1、运输注意事项∶管材、管件运输到工地后,材料搬运和储存应小心轻放,排列整齐。不得受尖硬物品刻痕、碰撞、不得抛、摔、滚、拖和烈日曝晒。管材、管件应储存在室内温不超过40℃的库房内,库房通风良好,不得与易燃物品等危险品同库储存。

2、施工前的准备工作∶管道安装工程施工前要求,地面一次面层打好;预留管沟位置,且沟槽清理干净;门窗到位;暖气片就位;施工现场清理干净后开始。

3、管道在安装前应对材料的外观和管材、管件配合工差、以及施工机具进行检查。管材、管件表面如有污物应及时清理干净。管道在安装过程中应严格防止油漆、沥青等有机物质污染管材、管件的表面。

4、PB管道的连接∶连接前应检查管材、管件端部清洁无损,断口平整光滑,无毛刺。管道连接的环境温度高于5℃热熔焊机应避免置于风口处,以免影响焊机的连接质量。PB管道系统的连接有热熔连接、电熔连接和夹紧式连接三种形式,在集中供热分户计量系统,推荐采用热熔连接方式。热熔连接利用专用设备加热后,用手工或机械进行压合连接。这种连接方式避免了金属管件连接出现在渗漏问题,施工便捷,安全可靠。

PB floor heating pipe

product description

PB floor heating pipe is synthesized by polybutene synthetic polymer, and contains crystals of special density (0.937). It is an advanced floor heating pipe material with high temperature resistance and high strength. It does not contain any additives during production and can be used in any floor heating and hot water pipe system. PB tube was born in the 1970s. It is currently one of the high-tech chemical materials and is known as the soft gold in plastics. It is relatively soft among several floor heating pipes, and the calculated wall thickness is relatively thin under the same design pressure. Under the same conditions of use and the same wall thickness series of pipes, this variety is safe to use. However, the price of raw materials is high, which is more than-times higher than other varieties. At present, the application area in China is small. It has been widely used in developed countries in Europe and the United States. It has replaced copper pipes as the choice of cold and hot water supply pipes. The market will gradually spread in the future. This kind of pipe.

Product performance standards

CJ/T372-2011 Random Copolymerization Polybutene Pipes and Fittings for Hot and Cold Water

Features

Feature keywords: polymer material, non-scaling, temperature resistance, impact resistance, flexibility, convenient construction

1. The quality of polymer materials is reliable: using PB resin as raw material, dry polyolefin (PB) has a higher degree of polymerization than other resins, with larger molecular weight and more stable molecular structure, so it has more

Strong thermal creep resistance and stress crack resistance, with a longer service life.

2. Non-scaling: non-scaling is the common advantage of plastic pipes. In addition, PB pipes can withstand most inorganic solvents, and can withstand most acids, alkalis, salt solutions and various chemicals at room temperature. Metal Tubes are incomparable with other plastic tubes.

3. High temperature and low temperature resistance: The high-quality PB floor heating pipes can not be frozen and cracked at -20℃~25℃, and can also be bent construction. At the same time, they can maintain the physical and chemical properties in 100℃ hot water.

4. Impact resistance: Due to the good flexibility of the PB pipe, the bending radius of the pipe is small, and the energy knife that absorbs water hammer and external impact is very strong, and the pipe is not easy to accidentally damage.

5. Excellent flexibility and resistance to temperature and strain: The thermal expansion coefficient of PB floor heating pipe is relatively small, but the flexibility is very high, and it is very easy to bend during construction. For places where the dry bending radius is not particularly small, pipe fittings can be completely eliminated, and because of the strong resistance to temperature strain, it is not necessary to consider the compensation of thermal expansion too much.

6. Convenient construction and easy maintenance: A variety of connection methods can meet the requirements of the same design and construction. When there is man-made damage, it can be connected by hot melt, which is easy to maintain, safe and reliable.

Product Usage

1. Low-temperature heating systems such as floor heating, water and floor heating, and air-conditioning piping systems.

2. Heating pipes: can be used to connect high-temperature heating systems such as radiators.

3. Hot and cold water pipes for tap water: pipes for direct drinking water projects. Solar residential warm water pipe: It is used for warm water and heating piping of solar residential housing.

4. Snow melting pipe: suitable for heating pipes for deicing and snow removal under highways and parking lots.

5. Industrial pipe: Because the material has strong chemical resistance, non-toxic and tasteless, it can be used in chemical engineering, food processing, industrial water and other fields.

Transport and installation

1. Precautions for transportation: After the pipes and fittings are transported to the construction site, the materials should be handled and stored carefully and arranged neatly. Don't be nicked, bumped, thrown, dropped, rolled, dragged, or exposed to the hot sun by sharp or hard objects. Pipes and fittings should be stored in a warehouse where the indoor temperature does not exceed 40°C. The warehouse is well ventilated and must not be stored in the same warehouse with flammable materials and other dangerous goods.

2. Preparations before construction: Before the pipeline installation project is required, the ground surface should be laid once; the trenches should be reserved and the trenches should be cleaned; doors and windows are in place; radiators are in place; the construction site is cleaned up and started.

3. Before installing the pipeline, check the appearance of the material, the mismatch of pipes, fittings, and construction equipment. Any dirt on the surface of pipes and fittings should be cleaned up in time. During the installation of the pipeline, it is necessary to strictly prevent organic substances such as paint and asphalt from polluting the surface of the pipes and fittings.

4. Connection of PB pipeline: Before connection, check that the ends of the pipes and fittings are clean and undamaged, and the fracture is smooth and free of burrs. The ambient temperature of the pipe connection is higher than 5℃, and the hot-melt welding machine should not be placed at the tuyere, so as not to affect the connection quality of the welding machine. The connection of the PB pipeline system has three forms: hot-melt connection, electro-fusion connection and clamping connection. In the centralized heating household metering system, the hot-melt connection is recommended. The hot-melt connection is heated by special equipment and then press-fitted manually or mechanically. This connection method avoids leakage problems in the connection of metal pipe fittings, and the construction is convenient, safe and reliable.
