PP butterfly valve

Installation method of PP pipe fittings

Before bonding pipes and fittings, wipe the socket side and outer side of the socket with a dry cloth. If there is oil stains on the surface, wipe it clean with acetone.

2. The cross-section of the pipe should be flat, perpendicular to the pipe axis, and chamfered; Before bonding, the insertion mark should be drawn and a trial insertion should be carried out. The trial insertion depth can only be 1/3~1/2 of the original depth. It is strictly prohibited to use bonding methods when the gap is too large.

When applying adhesive, the inner side of the socket should be applied first, followed by the outer side of the socket. When applying the socket, an appropriate amount should be evenly applied from the inside out along the axial direction, without omission or excessive application (200g/m2).

After applying the adhesive, it is advisable to maintain the applied external force for 1 minute to ensure the straightness and correct position of the interface.

5. After the bonding is completed, the excess adhesive extruded should be wiped clean in a timely manner, and no force or forced loading should be applied during the curing time.

6. Adhesive joints shall not be constructed in rain or water, and shall not be operated below 5 ℃.

7. Connection program: Preparation → Cleaning the working surface → Trial insertion → Brushing adhesive → Bonding → Maintenance.
