Four-hole grid tube 2.2mm_ four-hole grid tubes offer Although our four-hole grid tube design standards are not perfect, in the formulation of laws and regulations to keep up with the pace of development of the industry yet, there are still quite a few areas in some specifications blank, but the four-hole grid tube industry has formed a number of self-default design specifications: 1 To Water Supply and Drainage pipes buried four-hole grid layout plan to fully implement the skills of national economic policies, so that advances in technology, cost savings and ensure quality. 2 towns and industrial companies generally dedicated approach to water and wastewater engineering, the transport medium temperature is below 40 ℃ buried RPMP pipe layout plan adopted arc artificial soil foundation, while ensuring non-toxic health transport water quality, rigorous four hole grid tube material doped affect the water quality of harmful substances. 3 in accordance with existing national scale, "Water Supply and Drainage pipe layout plan paradigm" GB50332 delineated. Laying particular premise placement and construction inspection and earth production areas, loess soil and other geographic probably shrink four-hole layout grid pipeline engineering plans four four-hole grid tube buried pipe layout should suit the existing association will quasi "Buried Water Supply and Drainage glass fiber reinforced thermosetting resin sand pipe construction and inspection of the pipeline project" CECS129 delineated.
