Modified High Density Polyethylene (HDPE-M) Double Wall Corrugated Pipe for Burial

Modified high-density polyethylene HDPE-M double-wall corrugated pipe, the product is formerly known as nano-modified high-density polyethylene MUHDPE alloy pipe.

execution standard: T/CECS 10022-2019 "Buried modified high-density polyethylene (HDPE-M) double-wall corrugated pipe" formulated by China Engineering Construction Standardization Association.

basic characteristics:

Buried modified high-density polyethylene (HDPE-M) double-wall corrugated pipe is first modified and granulated to obtain special materials, and is extruded by automatic high-speed HDPE-M double-wall corrugated pipe production line. The special material is made of high-density polyethylene resin as the main component, and an appropriate amount of inorganic nanoparticles, high molecular weight copolymerizers, special additives, etc. are modified and granulated by a reciprocating single-screw extruder. It has the characteristics of high flexural modulus, good impact toughness and excellent performance, and finally gives the pipe excellent comprehensive properties.

1, excellent mechanical properties: ring stiffness 12.5kN/m ^ 2 or more (suitable for domestic actual construction and application of national conditions), ring flexibility 40% or more, impact resistance (-5) ℃/12.5kg/m ^ 2, to meet harsh construction conditions and possible brutal construction operations;

2, excellent mechanical structure: excellent mechanical properties: the pipe is made of modified high-density polyethylene special material, and the material bending modulus is high, up to 1250MPa or more. Due to the use of double-wall corrugated structure, the pipe and soil work well together, giving the pipe good compressive strength and high ring stiffness up to 20kN/m2 or more.

3, the connection method is convenient and the anti-settlement performance is good: the socket/sealing ring connection is used, which is convenient and fast, safe and reliable, and avoids being affected by artificial, weather and environmental factors. And light weight, easy to handle. At the same time, the creative design of the anti-fall joint can deal with certain geological settlement, which can ensure that it does not fall off and does not leak under certain geological settlement conditions, so as to ensure that the foundation is not initialized and prevent road collapse accidents.

4, large diameter range: covering DN200-DN1500, can meet the use of most engineering projects;

5, excellent corrosion resistance: all-plastic material, using modified high-density polyethylene special material, without any metal material reinforcement, through the modification of high-density polyethylene material to enhance the head

;

6, forming process integration: hot extrusion, one-time molding, no weld marks, smooth inner wall, small water flow resistance;

7, good anti-aging performance: pipe material added special anti-aging additives, while the sealing ring with EPDM rubber, improve the anti-aging performance, long service life, up to more than 50 years; 8, quality control is guaranteed: the color is light, using new raw materials modified, to eliminate the possibility of secondary material addition;
