When you are on the go and need support sizing Gastite/Flashshield CSST runs while in the field, Gastite has developed Mobile Apps to run on both Android and iPhone Tablets or Phones!  Gastite CSST Sizing: Mobile Sizing App - iPhone & Android.

Gastite releases new mobile applications to assist its customers in pinpointing the appropriate size Gastite flexible gas piping for their projects. Use scroll wheels to select length of run, supply pressure, pressure drop and flow rate, then let the app do the rest of the calculating for you.  Now available for FREE download in iTunes and Android.

Or, if you don't want to use a mobile App; Gastite has a number of other line sizing options available.

Gastite offers advanced sizing services on all commercial projects at no charge. Years of experience and collaboration with industry's finest are applied to deliver designs that render the most efficient gas piping installations. Submit your next project to Gastite!

Size-It

Design the layout of your gas supply system using Gastite's Size-It software. Based on the design you create, the appropriate pipe sizes will be calculated automatically. A materials list will be generated, including recommended components and estimated material costs.

Size-It

With Gastite's Excel-based workbook, it's easy to calculate the pressure at the start and end of a run. Use this resource to enter the details for your gas system and determine the sum of pressure loss. There's even a worksheet with a reserved area to enter a drawing of your project.

Recently we have fielded a number of calls on performance issues of HDP Autogas pumps of all makes and models.  One of the most common installation issues, has been undersized pump bypass lines back to the tank.

The traditional cylinder filling pumps have flow rates in the 2.5 to 11 gallons per minute (GPM) range.  And a large number of these pump systems used 5/8" copper tubing for the bypass line back to the tank.

WHICH is the issue we are finding in the field today with many of the HDP Autogas pump installations.  Installers are using 5/8" copper lines for the bypass to tank lines and creating additional differential pressure issues with that restrictive size line.

The HDP Autogas pumps have flow rates (depending on models) in the 8.5 to 34 gallon per minute range; significantly higher and requiring larger bypass lines to prevent additional differential pressure to the system.

A large number of dispenser sites using the mid-sized HDP Autogas pumps installed with the manufacturer recommended bypass valve; are installed with undersized bypass lines back to the tank which are causing higher than bypass valve factory setting differential pressures.

In one example the installation included a manufacturer recommended bypass valve with a factory setting of 150PSI differential; which was installed with 5/8" copper line for the bypass back to the tank.  When tested, this system was showing a differential pressure 15 psid higher than the factory setting due to the restriction caused by the undersized bypass line.  In this particular installation the excessively high differential pressure exceeded the pumps maximum design and was causing the pump to cavitate under normal operation.  The recommended solution would be to replace the undersized copper bypass line with 3/4" schedule 80 pipe or an alternative solution would be to re-adjust the bypass setting to reduce the actual differential pressure to 150 psid or less (recommend 120-140 psid) from the effective 165psid.

It is recommended that the mid-sized model HDP pumps (LGL156 & FF/DLF075) of HDP Autogas pumps utilize a minimum of 3/4" schedule 80 pipe bypass to tank line.   

AND REMEMBER, on every pump installation, you should test and set the actual system differential pressure according to manufacturer's guidelines. 

Application

Designed especially for use as a primary relief device on large stationary pressurized storage containers, the base is supplied with a two inch NPT threaded container connection. These manifolds incorporate an additional relief valve, not included in the flow rating, allowing for servicing or replacement of any one of the relief valves without evacuating the container. The hand-wheel on the manifold selectively closes off the entrance port to the relief valve being removed while the remaining relief valves provide protection for the container and its contents. All manifold flow ratings are based on flow through the relief valves after one has been removed for service or replacement.
