4.2 Installing and Mounting the Tube
Observe the general rules of hanging and mounting:
■
Fixed tubing should not be used as support for other tubing and
components.
■
Do not use pipe hooks.
■
Observe distance between fittings and mounting points.
■
Observe the expansion direction – plan fixed and sliding mounts.
4.2.1 Pipe Hangers and Supports
Tubing supports perform two functions:
■
To provide support for the tubing.
■
To guide the tube during thermal expansion and contraction.
Fittings must not be used as support
■
System malfunction may result from additional stress and
strain put on the fitting.
■
At no point in the system should a fitting be the sole means
of support. For example, when installing a tee, both the
branch and the trunk must be properly supported.
Industry standard practices and guidelines shall be used for tube layout
and support. Viega press connections require no special consideration for
support.
Hangers and supports must conform to the local code requirements. In
the absence of local code requirements, hangers and supports should
conform to ANSI/MSS SP 58 Pipe Hangers and Supports - Materials,
Design, Manufacture, Selection, Application and Installation.
4.3 Space Requirements and Intervals
Not enough space
The connection may leak and/or ring/press gun may not fit
around the fitting.
■
Adhere to minimum space requirements.
■
Make sure that the space required for pressing tools is
available if fittings will be pressed immediately upstream or
downstream from wall or ceiling penetrations.
■
Take the minimum required distances into consideration
during the planning phase of the project whenever possible.
