Post-Installation

Following the successful completion of the IQ and OQ protocols, one can then proceed to the post-installation tasks. These tasks include both performance qualification, as well as re-validation, re-calibration and maintenance. 

PQ can be defined as verifying that a system is capable of performing or controlling the activities of the processes it is required to perform or control, according to (the user s) written and pre-approved specifications (URS), while operating in its specified operating environment — ISPE/GAMP4. 

While both the IQ and OQ are typically carried out on an individual instrument basis, it is now common for the PQ to be designed and

Proper installation of V-belts is necessary to ensure trouble-free operation and maximum service life of the belts. The procedures and practices that should be followed in a proper installation can be broken down into three major categories pre-installation inspections of the belt and pulley, installation practices, and post-installation practices (belt tension inspection and adjustment). 

Post-installation practices are belt tension inspection and adjustment. 

Post-installed bolts will be required at times for attachment of equipment which may be subjected to large accelerations during a blast. Expansion anchors should be avoided for most blast design applications unless the load levels are low. Typically "wedge" type anchors are qualified for dynamic loads although most of these ratings are for vibratory loads and are based on cyclic tests at low stress levels. These should only be used where ultimate loads are less than the rated capacity with a margin of safely. Epoxy anchors have shown excellent dynamic capacity and may be considered for critical applications. 

Post installation modifications. Many times, new applications for make-up water are developed within the facility. In some cases, the easiest take-off point location is the make-up pipe to the RO system. However, if the new demand for water is significant, it will starve the RO system. 

IPC based applications require post installation support to ensure the system is used effectively and the validated status of the system is maintained. The system must be governed by the Quality Management System in operation at the system s location, i.e., change control, IT management procedures, and security procedures governing the granting and removal of system access. 

Category III (External Response) Community Emergency This level will be declared when events are likely to occur or have occurred that involve agent release with the predicted chemical agent no-effects dosage distance extending beyond the post-installation boundary.

The objective of this committee was to update the previous report, summarizing the State-of-the-Practice for the design of cast-in-place anchor rods, welded anchors, and post-installed anchors as used in petrochemical facilities. 

The committee recognized that while several different types of anchorage systems are used in pehochemical facilities, the most common types are cast-in-place anchors, welded anchors, post-installed anchors, and shear lugs. Therefore, for this report, the committee limited its investigation and recommendations to these common types. This self-imposed limit should not be construed as an attempt to limit the importance of other types of anchorage systems. Instead, this limit allowed the committee to focus attention on the most commonly used deviees. 

Chapter 5 has been added to present installation and repair information, focusing on post-installed anchors, constructability, and repair procedures. 

ACI Committee 355 published the State-of-the-Art Report on Anchorage to Concrete in 1991. This was the first of a two-volume set whieh emphasized behavior and did not include design methods and procedures. In 2000, ACI Committee 355 published the ACI Provisional Standard, Qualification of Post-Installed Mechanical Anchors in Concrete (ACI 355.2-00) and Commentary (ACI 355.2R-00). This document prescribed testing programs and evaluation requirements for post-installed mechanical anchors intended for use in concrete rmder the design provisions of ACI 318/318R-02. It was designated an ACI Standard in 2001 and has since been updated twice, most recently in 2007.

This chapter provides the basic materials, properties, and corrosion protection recommendations for holt and rod assemblies, headed studs, post-installed anchors, and shear lugs. The engineer must select the proper material, considering properties such as grade, yield strength, tensile strength and weldability and provide for corrosion resistance so that the anchorage will perform as required and intended. 

Post-installed anchors are manufactured in a variety of materials. A detailed discussion of post-installed anchors is presented in Chapter 4. The engineer should consult the manufacturer of proprietary systems for materials used, and select the most appropriate material for the intended use of the anchor and the environment in which it will be used.
