1. The lining process for Pipes positively locks the plastic liner in the metal pipe housing while effectively relieving stresses that could cause unwanted liner movement in service.
2. The liner is processed under controlled conditions to a size somewhat larger than the I.D. of the steel housing into which will be installed. It is then thoroughly inspected for conformance to specifications. Next, the liner is subjected to a battery of quality tests designed to ensure liner integrity.
3. The liner is then drawn through a sizing die at carefully controlled draw rates which results in a calculated reduction in the outside diameter.
4. A programmed heating cycle relaxes the liner inside the steel housing, resulting in a sung liner fit. Design allowances are incorporated in this procedure to eliminate undesirable stresses in the finished product.
5. Both liner ends of the pipe spool are then hot flared. Temperature, time and pressure are carefully monitored.
6. The finished pipe is then tested in accordance ASTM F1545 standards.
7. This unique lining process provides lined pipe with dimensional stability under vacuum, pressure, and thermal cycling conditions, which prevents liner buckling and cracked flares within operational limits.
8. All fittings are lined by automated Transfer/ Injection moulding process.
