CONTROLS DURING PRODUCTION

uPVC profiles which form the pipe are produced before producing spirally wound uPVC pipes. Required norms fort he pipes are ensured only if these profiles meet the required technical conditions. Physical properties of the extruded PVC profiles like wall thickness, T thickness, colour, appearance, roughness coefficient are controlled. 

A) RAW MATERIAL-AUXILARY MATERIALS TESTS AND CONTROLS

PROFILE

Tests applied to uPVC, the raw material of the profile; 
1) Determination of Vicat softening point
2) Determination of density
3) Determination of ash

The controls applied to the profile during production;
1) Appearance controls
2) Dimension controls

PIPE AND FITTING ADHESİVE

The tests applied to the adhesive;
1) Appearance
2) Viscosity
3) Dry Material

B) MEASUREMENT OF DIMENSION, GEOMETRY AND PHYSICAL PROPERTIES (TS12132)
1) Appearance
2) Dımension Control (external diameter)

C) PERFORMANCE TESTS OF END PRODUCT (TS12132)
1) Determination of tightness of the joints – This test is applied in accordance with TS 12132 If tightness of the joint is requested to be determined by air, then the test shall be applied in accordince with TS EN 1610 Part 13.2
2) Impact Resistance
3) Circular rigidity
4) Determination of strength of joints
5) Determination of tightness of the locks
6) Determination of tensile strength of lock point
