Q
Ovality of linear low-density polyethylene pipes exceeding standard
Q
Mechanical properties of linear low-density polyethylene extruded products not meeting standards
Q
Excessive gel/gel particles in linear low-density polyethylene extruded products
Q
Bending deformation of linear low-density polyethylene extruded pipes
A
Pipe bending is caused by non-uniform cooling or haul-off eccentricity and needs to be solved from cooling uniformity and equipment alignment.
