Installation
This section defines the general procedure for installation of a PLIDCO Clamp+Sleeve.
1.
If the two sleeve halves were shipped as an assembled unit it would have been shipped with spacers
between the two halves to prevent damage to the longitudinal seals and ends of the circumferential
seals. Typically, small diameter nuts are used for the spacers. The spacers must be removed and
discarded before installing the PLIDCO Clamp+Sleeve. Failure to remove the spacers will prevent
proper compression of the seals and clamping sections.
2.
Coat all exposed surfaces of the seals with a lubricant. Table 1
lists the lubricants that are
recommended for the various seals. The customer must determine if the lubricant is compatible
with the product in the pipeline. Lubricant is not recommended for underwater installations or for
braided packing. Refer to the section on Underwater Installations.
