16 Jan 2013--CPVC Dryer Bearing Drains 
As we have stated previously, we are going to be taking the ideas developed in this column over the last couple of years and developing them into design practices.  This is how it works.  We will provide the basic narrative here for one design practice each week.  We will keep it open for comments for one month.  After that, we will finish it in formal form and offer it for sale at a modest price.  Here is where you come in.  If you make a substantive contribution to a standard, the organization for which you work will be granted a pro bono license to use that standard with its current issue number for as long as you like.  We have had good response so far!  Contribute, please.

This one is a little weak, we admit it and we will be adding to it.  We are still working to get ahead a bit.  However, this gives you a chance to show your stuff.

This week's:  CPVC Dryer Bearings Drains Design Practice. (LGM 2013.011.01 when issued)

Reference:

Chlorinated Polyvinyl Chloride (CPVC) is a thermoplastic which possesses properties that makes this material desirable for many industrial applications, and is ideal for use as dryer bearing drains. Not only is CPVC pipe rated for higher temperatures than regular PVC plastic piping but it is also chemical and fire resistant, possesses high-tensile and high-impact strength capable of withstanding high pressure for long periods, offers internal and external corrosion resistance, low friction loss, low thermal conductivity, easy installation and is maintenance free.

 

Objective:

Utilize CPVC piping for Dryer Bearing Drains

 

Consideration:

CPVC pipe selection depends on the type of application. Items to be taken under consideration include:

  • Dimensions for industrial CPVC pipes - CPVC Schedule 40 and Schedule 80 pipe
  • Friction losses for CPVC pipes and fittings
  • Operating and collapsing pressure ratings
  • Support Spacing
  • Handling and Storage
  • Installation, including joining techniques

 

Methodology:

  • Identify operating conditions and parameters
  • Carry out the necessary calculations taking into account the above considerations
  • Utilize correct installation and joining techniques
  • Conduct the necessary tests on the Thermoplastic Piping System - there are a number of methods to do this

 

So, give us your comments by 13 Feb 13, please!

 

 

Still open for comments Foundation Design Practice.  (Open until 6 Feb 13)

 

 

And we will be doing something else with the weekly ideas--we will be discussing many of them in a round table discussion at the LGMI Annual Conference January 27 - 29, 2013 here in Atlanta.  You can attend in person for free or online for a nominal costs.  You will need to sign up soon as openings are limited.  Sign up here.

As always, your comments will be appreciated.

 

Think light!

Want to support
the Light

Institute?
The Light Green Machine Institute is currently supported by Talo Analytic International, Inc., a for-profit corporation.  As such, our ability to create and develop new initiatives is limited.  Should you feel so inspired as to assist in the financial support of this effort, we would be most appreciative.  Check with your tax adviser as to the status of any funds expended here.  You may help the LGMI by going here.

Please be advised, the Light Green Machine Institute is currently financially integrated into Talo Analytic International, Inc.  As such separate or public accounting is not available.  It is our aspiration that we can grow the Light Green Machine Institute into a standalone 501C3 corporation, however, we consider this speculative and highly risky at this time.
