Pipe demand in the construction engineering at present in our country on the quality requirements gradually increased, and PVC pipe is plastic pipe in the main pipe, PE pipe is nearly ten years began to use, application time relatively late and less, with the pace of progress of the times, environmental awareness increasing, of PVC pipe material to bring some attention, non-toxic, no pollution, and can be recycled. Pipe fittings, and constantly improve the technology innovation, improve the construction efficiency is not short, the application of continuous widely done.
Development to today's situation, before you get a lot of experience: complaints, fittings is not perfect, content exceeded the standard, technical stop all sorts of influence. Until the early 1980s, countries vigorously promote outward PVC pipe applications, so businesses for the material requirements and quality gradually upward, production will continue to own research and development, improve product standards, the pace of development into the mature stage, in order to ensure the quality and development of PVC pipe.
