China's plastic pipe industry has been rapid development of plastic pvc pipe fittings, pipe products from plastic pipe market in the expanding plastic pvc pipe fittings manufacturer, has become a ubiquitous product has been widely recognized as an important industry. Plastic pipe products are all aspects of attention, especially in the construction sector, the water sector, public works engineers and technicians in the field are very concerned about, understand, study plastic products. "Fifteen" period, the rapid growth of the plastic pipe industry, and promote the technological progress of the industry. Many enterprises attach great importance to the international forefront of technology, to the introduction of plastic pvc pipe fittings develop new products and new technologies, and in the introduction of advanced processing equipment at the same time, continue to strengthen the research and development of new products. Some large companies have their own advanced level of research and development centers, with a strong technical strength. Domestic plastic pipe industry already has 300 number of inventions, new patented technology, and some proprietary products leading position in the International Office. The gap between the technical level with the developed countries is gradually narrowing, has evolved from a simple import substitution into an international export products. Variety, structure, new materials, new technologies, new processes and patents more and more plastic pipe, a variety of different types of plastic pipe is playing to their strengths in different applications. Polymerized plastic pvc pipe products under bulk production process in water, no dispersant, only adding initiator condition does not require post-processing equipment, small investment, energy efficiency and low cost. Product transparency bulk PVC resin production with high electrical insulation, easy processing, processing equipment suspension resins can be used for the processing of bulk resin. PVC body process has been greatly developed in the 1980s. However, despite theoretically reaction process to produce resin suspension and bulk polymerization can be used in the same field, in fact, plants generally use only one of them, because of the suspension and the body resin can not be mixed, even a small amount of mixing also due to electrostatic effect leading to reduced polymer powder flowability, and suspension polymerization of the resin easier to get, so most plants gave up the body resin, bulk process in recent years there has been stalled or declining state.
