Just Scroll down to get to some great technical data on each of these subjects
Monoflanges and Instrument Manifolds are used as an alternative to multivalve systems. They have been specifically designed to provide a compact installation for gauge or transmitter instruments. An application where a monoflange is used is in place of other equipment. For example, the instance where instead of having one valve and relying on it to close so that a transmitter can be isolated, two valves are used. A double block and bleed monoflange can be used in place of the two valves. It takes away that need for two valves and reduces it all into one. That is the monoflange has two valves on it, which are closed, and a vent that is opened to reduce the pressure between. It has reduced weight and minimum leak paths providing a higher integrity system. The reduced length of the installation also reduces the risk of damage through vibration.
Monoflange manifolds can be mounted directly onto vertical or horizontal flanged connections, allowing a gauge to be kept in an upright position. Suitable for both primary isolation (double block and bleed) and instrument (block and bleed) duties a Monoflange provides isolation, venting and instrument mounting in a single compact unit. The designs incorporate safety features that limit vibration and reduce the overall height of a gauge installation.
In order to ensure System Integrity one must not lose sight of the fact that Monoflanges and Instrument Manifolds are subject to Process Conditions eg., pressure and temperature, therefore it is important to purchase high quality units.
What does NPTF thread stand for?|
NPT thread stands for National Pipe Taper. It refers to the thread that tapers
inward to create a better seal. It is recommended that care is taken in
regards to the thread tolerances and only the best quality units are purchased
to achieve this. It is imperative that any manufacturer has demonstrated quality
assurance to a high standard. It is worthwhile ensuring the quality of threads
by gauging at least a proportion of the threads to ensure compliance. Also it is
recommended that thread tolerances and gauging should be specified to a
tolerance better than the requirements of ASME B1.20.1. ICEweb's compression
fittings page has a more detailed explanation of the gauging and tolerance
requirements.
What is an OS&Y valve?
An OS&Y valve is an Outside Screw and Yoke valve. It is a part of the piping
specification. It has a firesafe outside screw construction.
Why is the Molybdenum content of 316SS 2% minimum in an offshore environment?
The molybdenum content is at a minimum 2% to prevent chloride corrosion.
Why is 303 or 304SS not to be used in an offshore environment?
303 or 304SS is not to be used because their molybdenum content is nil and thus the
material is subjected to chloride corrosion.
Is there a maintenance issue when Close Coupled Monoflanges are used? If the Monoflange is installed on a clean, non blocking process then it is not an issue in that access to the tapping point is required very rarely. This is especially so on Fieldbus and HART systems as the transmitter provides a huge amount of diagnostics on-line. The huge advantage of Close Coupling is that many instrument fittings are no longer required, thus eliminating potential leak failure points.

Conversion Chart - Some useful conversions
Duplex
Stainless Steels - Duplex
Stainless Steels are unlike the 300 (Austenitic) and 400
(Ferritic) series of stainless steels in that they have a structure
consisting of approximately equal amounts of both
ferrite and austenite. Therefore, they are often referred
to as ferritic-austenitic stainless steels. With a
chromium content ranging from 18 to 28 percent, they
have improved passivity compared to standard grades.
The nickel content ranges from 4.5 to 8 percent which
is insufficient to promote a complete austenitic crystal
structure, hence the mixed ferrite-austenite
structure. Most grades contain molybdenum in the
range of 2.5 to 4 percent plus small amounts
of nitrogen – enhancing both strength
and pitting resistance.
Flanges
- A flange is designed to connect sections
of pipe, or to join a pipe to an assembly such as a pressure vessel, valve
or pump. Flanges are joined by bolting, and sealing is
completed with the use of gaskets, and fixed to the piping system
by welding or threading.
JIC
Fittings - JIC Fittings and
Adaptors provide a straightforward, positive,
mechanical seal. They have been used for many years for reliable
sealing in commercial, industrial and military applications. They are proven to
supply dependable, reusable connections under a
wide range of operating conditions including
extremes of vibration, temperature and shock.

Instrument Company offers a comprehensive line of variable
area flow metres including acrylic, polysulfone, glass
and metal tube metres. Optional alarms and 4-20 mA transmitter
available on selected models. See more technical information on ICEweb's
Flow page.
Manual
Sample Systems - Due to the growing
complexity of the industrial processes in general and more
specific for processes in the (petro)chemical and pharmaceutical industries,
the need for tests and analyses increases continuously. The
need for representative samples plays a critical role in ensuring product
verification. Yet sampling directly from the process often includes the
risk of exposure to the operator, as well as contamination and pollution
to the environment. The Manual Sample Systems method reduces
such risks with its patented design and simple method of operation.
NPT
Fittings - NPT fittings are designed for
high-pressure (class 3000 - class 6000) applications,
and have a distinctive profile for maximum strength. All
NPT products are checked with calibrated gauges
during the manufacturing process and each batch is further confirmed
as being in compliance with the international thread standard. Before
they are released into the market, each item is subject to a final visual
and dimensional inspection by thread profiling.
Materials used comply with ASTM A403 or
A182.
O'Brien
Tracepak - The economical choice to
field fabrication - Maintenance free TRACEPAK not
only saves money and time during the
installation process, but it ensures consistent,
repeatable performance. Field fabrication requires
a pipe fitter to lay out, measure, cut, dress, bend
and install the tubing. Next the tracer (steam or
electric) has to be installed and insulation put on
the tubing. Finally, a weatherproof covering needs
to be applied over the insulation. Clearly the
economics of the TRACEPAK system versus field
fabrication are significant.
O'Brien
Analytical - TrueTube is a family of tubing products
developed to provide best-of-breed performance in sample transport for process
and emissions analyzers. O’Brien Analytical starts with select grade tubing
and enhances its physical characteristics to improve dry-down, adsorption and
corrosion resistance. This is achieved by controlling surface roughness,
cleanliness, surface chemistry and reactive contaminants.
Offshore Oil and Gas Speciality Valves - Pacson Valves - These are high integrity valves specifically designed for the Oil and Gas Industry.
Offshore Oil and Gas Speciality Valves - ATC Actuators - The heart of the ATC actuator design is the revolutionary torque conversion mechanism combined with the integrated actuator spring. The simple operating principle offers a combination of high efficiency and small displacement, thereby creating greater design flexibility and improved reliability. This design flexibility, combined with the innovative integration of all actuator parts, results in the most compact actuator available in the market. In virtually all applications, irrespective of hydraulic or pneumatic supply, the ATC actuator diameter is smaller than the Face-to-Face dimension of the valve.
