How to bond the thermal expansion seamless steel pipe :
1. Thermal expansion pipe before bonding, dry cloth and the outer side of the socket socket wipe process, when the sticky surface oil to be wiped clean with acetone.
2.

3. Apply adhesive should be applied inside of the socket, smear the outside of the socket, the socket should be applied along the axial direction from the inside out evenly amount, shall not apply or drain excess coating (200g / m2).
4. After the adhesive applied, the external force should be applied within 1 minute to keep the same, straight and position connectors are properly maintained.
