Quality is a kind of faith, and PUHUI regards “product quality” as the life! Puhui will take strict quality control from the raw material to finished products.

Quality Control

Raw Material

The quality control test of HDPE pipe raw materials is typically carried out by a team of quality control engineers. The engineers will use a variety of tests to ensure that the raw materials meet the required specifications. Some of the tests that may be used include:

Density testing

This test measures the density of the resin to ensure that it meets the required specifications.

Melt flow index testing

This test measures the flowability of the resin to ensure that it can be properly processed.

Molecular weight testing

This test measures the molecular weight of the resin to ensure that it meets the required specifications.

Additive testing

This test measures the levels of additives in the resin to ensure that they are within the required specifications.

Visual inspection

This test involves inspecting the raw materials for defects, such as cracks, scratches, and voids.

HDPE Pipe Material

The quality control test of HDPE pipe raw materials is typically carried out by a team of quality control engineers. The engineers will use a variety of tests to ensure that the raw materials meet the required specifications. Some of the tests that may be used include:

Density testing

This test measures the density of the resin to ensure that it meets the required specifications.

Melt flow index testing

This test measures the tensile strength of the pipe to ensure that it can withstand the required loads.

Tensile testing

This test measures the burst pressure of the pipe to ensure that it can withstand the required pressures.

Hydrostatic testing

This test involves pressurizing the pipe with water to ensure that it does not leak.
