HDPE PIPE ADVANTAGES
Good toughness and flexibility. PE pipe is a kind of high-toughness pipe, its elongation at break exceeds 500%, it has strong adaptability to the uneven settlement and dislocation of the pipe foundation, and has good seismic resistance. Therefore, it is suitable for earthquake-hazardous areas. Practices around the world have proved that PE pipe is a pipe with good shock resistance. In addition, the flexibility of the PE pipe is that the PE pipe can be coiled, reducing a large number of connecting pipe fittings. The direction of the PE pipe can be easily changed according to the requirements of the construction method. During construction, obstacles can be bypassed within the allowed bending radius of the pipe to reduce the difficulty of construction.
Good stress cracking resistance: PE pipe has low notch sensitivity, high shear strength and segmental anti-scratch ability, and outstanding environmental stress resistance. Good low temperature impact resistance: The low temperature embrittlement temperature of PE pipe is extremely low, and it can be used safely in the temperature range of -60 degrees Celsius. Good abrasion resistance. The wear resistance comparison experiment of polyethylene pipe and steel pipe shows that its wear resistance is 4 times that of steel pipe.
Easy maintenance, can not stop water, gas maintenance and installation.
Good sealing. The PE pipe itself is welded and connected, which essentially ensures the identity of the interface material, structure and the pipe body itself, and realizes the integration of the joint and the pipe. The tensile strength and bursting strength of the interface are higher than those of the pipe body, which can effectively resist the hoop stress and axial stress generated by the internal pressure. Therefore, the sealing performance is very good compared with rubber ring type joints or other mechanical joints.
