The tensile properties of steel wire mesh skeleton composite pipes belong to mechanical properties. For most applications of polymer, mechanical properties are more important than other physical properties. High molecular polymers have mechanical properties with a wide range of variability in known materials, which is due to the relaxation of molecular motion due to the fact that polymers are composed of long chain molecules.
For example, high polymer materials have quite high elongation. Generally, the elongation at break of PE is 90%~950% (among which the elongation of LLDPE is higher). Generally, heat shrinkable film and stretched film have higher requirements for tensile properties of materials. For our actual steel mesh skeleton composite pipe.
Generally, the tensile property can be 200%. For example, when used as a drag tube, this data is ideal. Conversely, it is not good to have too good tensile property. Because the ring steel degree will decrease if the tension is too long, so reasonable product technical data is suitable for our daily application.
Electrothermal fusion connection is to insert both ends of the required connection into the sleeve embedded with the electric wire, energize the electric wire, heat the pipes and pipe fittings to be connected to the melting temperature, and fix them until the interface cools, so as to form a tight joint. The hot melt butt connection is to contact the two corresponding ends perpendicular to the pipe axis with the heating plate to the melting temperature, and press the two melting ports tightly. Hot melt butt connection is applicable to pipes with diameter greater than 90mm.
