The following article concerning the installation of a Olet type fitting and it's future with ASTM B31.1 was taken from a Bonney Forge News Release. PPI has the new ES-49 standard available.

August 3, 2009 - OLET® Specification Revisions (UPDATE)

Bonney Forge has collaborated with the Pipe Fabrication Institute (PFI) to produce their 2008 Approved Release PFI Standard ES-49, “Guideline for Installation of Integrally Reinforced Branch Outlet Fittings”, which covers in detail the basic welding procedure and recommended weld deposit criteria for OLET® fittings. Additionally, a revision has been proposed to B31.1 “Power Piping Code” clarifying the governing criteria used for weld size determination and provides depictions of some acceptable weld profile for “Integrally Reinforced Branch Outlet Connections”.

This proposal has favorably passed the sub-committee and is currently under ballot in B31.1 main committee. The approved revisions are Paragraph 127.4.8 and the addition of Figure 127.4 (G) showing acceptable details for integrally reinforced branch connections. This initial proposal consisted of the addition of Figure 127.4 (G),
“Some Acceptable Details for Integrally Reinforced Branch
Connections,” and the corresponding changes to paragraphs 104.3.1, 127.4.8 and 132.4.2, as well as the addition to paragraph 100.4.2 for the definition of an “Integrally Reinforced Branch Outlet Fitting”. These details have not previously been included in B31.1.
