In our lives, PVC lay flat hose are not only used in one aspect of fire protection, but are also widely used in agricultural irrigation in our development. As the number of manufacturers of PVC lay flat hose increases, there are also many differences in quality. Next, I will introduce the method of distinguishing the quality of PVC lay flat hose.
1, PVC lay flat hose manufacturers should strictly follow the PVC lay flat hose production standards, PVC lay flat hose blanks should be woven with 20 cross fibers and polyester yarn. Thickness is also required. It must be more than 1.5 mm. This value is not allowed in production.
2.When producing PVC lay flat hose, the pressure must also be controlled above 0.6 mpa, and the PVC lay flat hose produced is smooth. There are broken wires, drawn warp yarns, loose warp yarns, inner and outer grooves, deformation holes and coating inclusions, which are unqualified and cannot be produced.
3.Agricultural PVC lay flat hose shall comply with relevant production regulations of industry standards. The PVC lay flat hose blank is woven from 20 large chemical fiber polyester yarns. Its thickness must exceed 1.5 mm and a lower deviation value is not allowed.
4, agricultural PVC lay flat hose pressure must be above 0.6 mpa, the surface should be smooth and PVC lay flat hose, there should be no broken wire, wire warping, loose warp, inner and outer grooves, pore deformation, coating and other defects. tolerance.
