66.27.5 Pipe Joints
JUMP TO FULL CODE CHAPTER
Joints shall be made liquidtight and shall be welded, flanged, threaded, or mechanically attached. [30:220.127.116.11]
Joints shall be designed and installed so that the mechanical strength of the joint will not be impaired if exposed to a fire. [30:18.104.22.168]
Threaded joints shall be made with a suitable thread sealant or lubricant. [30:22.214.171.124]
Where such joints are used aboveground, either the piping shall be secured to prevent disengagement at the fitting or the piping system shall be so designed that any spill or leak resulting from disengagement will not expose persons, important buildings, or structures and can be controlled by remote valves. [30:126.96.36.199]
Pipe joints dependent on the friction characteristics of their components shall be permitted to be used inside buildings provided both of the following are met:
- They are located where leakage can be controlled by operation of an accessible, remotely located valve that is outside the fire risk area.
- The mechanical strength and liquidtightness of the joint is not dependent on the resiliency of a combustible material or component.
