Comparison of prestressed plastic corrugated pipe equipment and metal corrugated pipe equipment The types of bellows are prestressed plastic bellows and metal bellows. Among them, the pre-stressed plastic corrugated pipe is popular because of its lower cost and greater operability. The equipment used to manufacture corrugated pipes is also pre-stressed plastic corrugated pipes and metal cor
What are the points to note in the operation of the prestressed plastic corrugated pipe equipment? A. The main points of installation and operation of the refrigeration spiral tube. 1. The end of the ventilation pipe should be Ω-shaped or T-shaped, and the discharge port should be facing. There should be a shut-off valve between the equipment. During operation, it must be in a fully open p
What are the standards and technical requirements for prestressed plastic corrugated pipes? 1. Meet the transportation industry standard JT/T529--2004. 2. Use original granular raw materials. Do not use powdered and reconstituted granular materials. High-density polyethylene (HDPE) should meet the requirements of GB/T11116, and polypropylene (PP) should meet the requirements of GB/T18742
