There are two variations of the model 72, the 72SJ (steam jacketed) and 72L (Tefzel lined).
Models 72SJ and 72L
The steam jacketed version of the model 72 simplex strainer has a "cover" welded around the basket chamber with either ½" or ¾" threaded steam port connections depending upon the strainer size.
The jacketing process usually extends the lead time from 3 days to about 2 weeks.
The steam jacket is rated for 100 PSI @ 400°F maximum (6.9 bars @ 204.4°C). The model 72SJ is available in either cast steel or cast 316SS materials only.
The model 72L simplex strainer consists of a carbon steel body with a special Tefzel lining for handling aggressive fluids. The lining used for model 72L simplex strainers should not be confused with "coatings", rather it consists of a 1/8" thick plastic lining which enables it to handle aggressive fluids which would otherwise require a costly custom fabricate strainer made of an exotic alloy.
The Tefzel fluoropolymer lining is inert to strong mineral acids, inorganic bases, halogens and metal salt solutions. Aggressive fluids such as carboxylic acid, anhydrides, aromatic and aliphatic hydrocarbons, alcohols, aldehydes, ketones, ethers, esters, chlorocarbons and classic polymer solvents have little effect on the Tefzel lining.
The basket choices for the model 72L include 316SS perforated baskets with Tefzel coating, Monel or Hastelloy C (the latter two materials available for perforation or mesh lined retentions).
