Masoneilan 84003 Series Steamform
Installation
Installation of the Masoneilan 84002 series SteamForm
products requires a thorough understanding of the
surrounding operating environment. Product selection
and evaluation must extend upstream and downstream to
ensure proper design for successful long-term operation.
Baker Hughes’s installation guidelines are intended to
provide recommendations and warnings for the various
design elements of the steam conditioning system.
Enhancements to the overall performance of the system
are tested and documented through years of installed
experience and proven field-tested methods.
Piping System Layout
The design and layout of the piping system are
important factors for a successful installation of a steam
conditioning valve. Several performance factors are
highly dependent upon the proper arrangement of the
piping system. Without the correct design in place,
the steam conditioning valve becomes ineffective in
achieving temperature control and stability. Additional
Design requirements including selecting pipe size, laying
out upstream and downstream piping, and positioning of
control elements are explained throughout this document.
Upstream Pipe Recommendations
Adjacent pipe bends such as pipe elbows and tee
connections are known to cause high levels of rotational
forces and excessive vibration when installed in close
proximity to a valve body. Long-term exposure to this flow
induced vibration results in problems such as damaged
trim and excessive noise during operation.
To reduce these risks, a uniform and stable flow profile
must be achieved prior to admission of the steam into
the SteamForm valve body. This is accomplished by
supplying a length of straight pipe, L1, upstream of the
valve inlet as shown in Figure 1. A straight pipe section
allows the inlet steam to recover its uniform flow profile
after passing through the turbulent path of an elbow.
In the case of an upstream elbow installation, the
recommended distance of five pipe diameters of straight
pipe must be mounted upstream of the valve. Longer
lengths of straight pipe are also desirable.
Minimum upstream straight pipe length:
L1 = 5 x Nominal Pipe Diameter
Upstream tee connections involve further consideration,
as higher levels of turbulence are present in these
applications. These systems must supply a longer
length of upstream straight pipe, as higher levels of
instability exist. Consult your local Baker Hughes sales
office or factory for the recommended distance for these
applications.
