Quality control unit of Vala Polymer Company

Quality control of polyethylene gas and water pipes

Long-term planning in Vala Plimer Novin company and the policy of attracting and cooperating with customers on a permanent basis has led to the formation of a powerful quality control unit in this company. The quality control unit of the company makes continuous efforts in the production process and optimization of its products and with its strict and complete monitoring in all production stages from the arrival of raw materials to the storage of the product, it presents its reports to the management and summarizes this Reports on the appropriate solutions achieved will improve the quality control of manufactured products. All the specifications of the products produced in Vala Polymer Novin Company are specified and are monitored and measured to confirm that the requirements or demands related to the product have been met. Performance and evidence of compliance with acceptance criteria are maintained. The monitoring method and relevant criteria are determined according to national and international standards.
The tests performed in Vala Polymer Laboratory are as follows:

  • Melt flow index
  • Determination of tensile properties
  • Determination of induction time (Oxidative – induction time)
  • Determination of density
  • Determination of carbon percentage
  • Hydrostatic pressure test
  • Burst pressure test
  • Heat recovery test
  • Measuring the dimensions and checking the appearance of the pipe
  • Test to determine the amount of soot dispersion
