1. PVC pipe material advantages

在通用树脂生产中，以PVC树脂耗乙烯量最低，生产成本也最低。国内生产每吨PVC需耗乙烯0.5314吨，而每吨聚乙烯平均耗乙烯1.042吨，国内每吨PVC树脂的乙烯耗量比聚乙烯少消耗约50%。而生产PVC用的原料氯气，是平衡生产烧碱产生氯气的重要途径，烧碱是国民经济必不可少的十分重要原料。另外，从塑料制品角度看，PVC与各种助剂相容性好，在生产管材中可加入大量低廉的填料，使生产成本大大降低。

In general resin production, PVC resin has the lowest ethylene consumption and the lowest production cost. The domestic production of PVC per ton of ethylene is 0.5314 tons, while the average ethylene consumption per ton of polyethylene is 1.042 tons. The consumption of ethylene per ton of PVC resin per ton is less than 50% less than that of polyethylene. The production of chlorine used in PVC is an important way to balance the production of caustic soda to produce chlorine. Caustic soda is a very important raw material for the national economy. In addition, from the perspective of plastic products, PVC has good compatibility with various auxiliaries, and a large number of cheap fillers can be added to the production pipes, which greatly reduces the production cost.

PVC管材与金属管材相比，生产每立方米PVC和生产每立方米钢及铝计算，钢的能耗为316KJ/m3，铝的能耗是619KJ/m3，PVC的能耗为70KJ/m3，即钢的能耗是PVC的4.5倍，铝的能耗是PVC的8.8倍。而生产PVC管的加工能耗也仅为同口径金属管材的三分之一。同时由于PVC管壁光滑，不结腐蚀瘤，输水效率高，用于输液可节电20%左右。

Compared with metal pipe, PVC pipe and metal pipe, production per cubic meter of PVC and production per cubic meter of steel and aluminum calculation, the energy consumption of steel is 316KJ/m3, the energy consumption of aluminum is 619KJ/m3, the energy consumption of PVC is 70KJ/m3, that is, the energy consumption of steel is 4.5 times of PVC, and the energy consumption of aluminum is 8.8 times that of PVC. The energy consumption of producing PVC pipe is only 1/3 of the same caliber metal pipe. At the same time, because the PVC tube wall is smooth, does not corrode the tumor, the water delivery efficiency is high, for the infusion can save electricity about 20%.

PVC管材有很好的力学性能，且具备极好的耐腐蚀性，使用过程中重量轻，安装方便，不需维护，而使用钢铁作公用工程的下水管道，在使用过程中由于易腐蚀，必须经常涂敷涂料，维护费用高。一般建筑及公用工程用金属管道20年左右就需更换，而作用加工良好的PVC管道，使用寿命长达50年等。因此，PVC管材是一种生产成本低、强度高，耐腐蚀的良好塑料制品。

PVC pipe has good mechanical properties, and has excellent corrosion resistance. It has light weight, easy installation and no maintenance in the process of use. In the process of using steel as a utility pipeline, the coating must be often coated and the maintenance cost is high because of easy corrosion. For general construction and utility engineering, metal pipes need to be replaced in about 20 years, and the well functioning PVC pipes will last for 50 years. Therefore, PVC pipe is a good plastic product with low production cost, high strength and corrosion resistance.

一般来讲，在排污、废水和通风管道方面，PVC管道比使用铸铁管节约安装和劳务费用约16-37%；作导线管比使用金属导线套管节约费用30-33%；而作用氯化聚氯乙烯（PVC）管在冷热水方面，比使用相同尺寸的铜管节约费用为23-44%。因此，由于PVC管材的优势，各国均在积极发展和推广PVC管材。

Generally speaking, in the aspects of sewage, waste water and ventilation pipe, the PVC pipeline saves about 16-37% of installation and labor cost than using cast iron pipe; it saves 30-33% for the use of metal wire bushing for traverse tube; and the effect of chlorinated polyvinyl chloride (PVC) tube in cold and hot water is 23-44% compared to the cost of copper tube with the same size as using the same size. Therefore, due to the advantages of PVC pipes, all countries are actively developing and promoting PVC pipes.

2. PVC管材生产及消费情况

2. PVC pipe production and consumption

自八十年代以来，我国先后引进不同型号的PVC管挤压生产线上千条。目前，我国UPVC（硬质PVC）管材、管件生产厂有600余家，总生产能力110万吨/年以上，生产规模在1万吨/年以上的厂家有30多家，规模在0.5-1万吨/年的厂家有60余家，UPVC管材、管件的生产设备基本上实现了国产化。

Since 80s, various types of PVC pipe extrusion production lines have been introduced in China. At present, there are more than 600 UPVC (hard PVC) pipes and pipe fittings in our country, with a total production capacity of 1 million 100 thousand tons / more than 10 thousand tons per year or more. There are more than 60 manufacturers with a scale of 0.5-1 million tons per year. The production equipment of UPVC pipe and pipe fittings have basically been made domestically.

在我国，PVC管较PE管和PP管开发早，品种多，性能优良，使用广，在市场上占有重要位置。到1999年底，全国塑料管生产线约有2000余条，其中引进设备约占15%。1999年我国各种塑料管材的生产能力超过165万吨/年，实际产量100万吨左右，而其中UPVC管材占50%以上。

In China, PVC pipes are more developed than PE pipes and PP pipes, and have many varieties, excellent performance and wide use. They occupy an important position in the market. By the end of 1999, there were about 2000 plastic pipe production lines nationwide, of which about 15% were imported equipment. In 1999, the production capacity of various plastic pipes in China exceeded 1 million 650 thousand tons / year, and the actual output was about 1 million tons, of which UPVC pipes accounted for more than 50%.

这些年来，在世界PVC的市场应用中，以建材市场为最大，且增加速度也最快。近年来美国建材制品一直占其制品总量的60%，西欧为62%，日本为50%，我国比例则不到30%，上升空间很大。在建材制品中，又以管材和异型材为主，包括建筑上下水管，农用灌溉管，气体输送管，原油输送管等。

Over the years, the market for building PVC has been the largest and fastest growing market in the world. In recent years, building materials in the United States have accounted for 60% of total products, 62%wanji.89ix.com fengguan.89ix.comfengguanol.89ix.comtianchuangp.89ix.com jietou.89ix.com fenxiyi.89ix.comin Western Europe, 50% in Japan, and less than 30% in China. In building materials, pipes and profiles are the main components, including building upper and lower pipes, agricultural irrigation pipes, gas delivery pipes, crude oil conveying pipes, etc.

我国UPVC管生产和应用在"九五"期间真正开始得到迅猛的发展，主要得益于政府的大力支持和社会对UPVC管材的认识。

In the period of "95", the production and application of UPVC tube in our country really began to develop rapidly. It mainly benefited from the strong support of the government and the understanding of the UPVC pipe.

目前我国塑料管的应用不仅在数量上而且在品种和规格上得到了很大发展。如UPVC管在一些城市建筑排水应用上已达到90%以上，绝大部分UPVC管材企业这几年效益十分良好。

At present, the application of plastic pipes in China has not only developed greatly in quantity, but also in varieties and specifications. For example, UPVC pipe has reached more than 90% in building drainage applications in some cities, and most UPVC pipe enterprises have achieved very good results in recent years.

在"十五"期间，塑料管的推广应用主要以UPVC和PE塑料管为主，并大力发展其它新型塑料管。到2005年，在全国新建、改建、扩建工程中，建筑用排水管道50%采用塑料管，城市排水管道20%采用塑料管，建筑给水、热水供应和供暖管道60%采用塑料管，城市供水管道（Dn400以下）50%采用塑料管，村镇供水管道60%采用塑料管，城市燃气管道（中低压管）50%采用塑料管，建筑电线穿线护套管80%采用塑料管。预计2005年需求塑料管材约200万吨以上，其中绝大部分为PVC管材。

During the "fifteen" period, plastic pipes were mainly applied to UPVC and PE plastic pipes, and other new plastic pipes were developed vigorously. By 2005, in the new construction, reconstruction and expansion projects in China, 50% plastic pipes were used for construction drainage pipes, 20% plastic pipes were used in urban drainage pipes, 60% plastic pipes were used in water supply, hot water supply and heating pipes, 50% of urban water supply pipes (below Dn400) were used plastic pipes, and 60% plastic pipes were used in village water supply pipes. The city gas pipeline (middle and low pressure pipe) 50% uses plastic pipe, and the building electric wire through protective sleeve 80% adopts plastic pipe. It is estimated that plastic pipe needs more than 2 million tons in 2005, most of which are PVC pipes.

在发达国家中，PVC管消费量一般占塑料管市场的70-80%，而我国PVC管仅占塑料管的总量的50%左右，我国PVC管的发展潜力十分巨大。发达国家PVC各种管材的消费比例是：供水管占33%，下水管占22.3%，排污管占15.7%，灌溉管占5.2%，煤气管占0.8%，其它管材占22.7%。其中管件与管材的消费量比约为1：8。

In developed countries, the consumption of PVC pipe generally accounts for the 70-80% of the plastic pipe market, and the PVC pipe in China accounts for only about 50% of the total plastic pipe, and the development potential of the PVC tube in China is very great. The consumption proportion of various pipe materials in PVC in developed countries is: 33% of water supply pipe, 22.3% for sewer pipe, 15.7% for sewage pipe, 5.2% for irrigation pipe, 0.8% for gas pipe and 22.7% for other pipes. The consumption ratio of pipe fittings and pipe is about 1:8.
