Hydro requirement for Temporary Boiler
Hydro requirement for Temporary Boiler
(OP)
Hi All,
I have a few questions I am looking for some advice regarding the installation of a temporary rental boiler:
1. Does the code give any allowance for hydro of Boiler external piping for a temporary installation? The boiler external piping is a spool piece of about 1'-6" long with a drain on it.
2. Who's responsibility is it to specify for hydro, the engineer or the S stamp holder?
3. B31.1 gives allowance for an in-service leak test in lieu of hydro. Is there such provision in Sect. 1?
Thanks in advance.

Check with your local Jurisdiction that regulates boilers where this will be installed.

No. Installation activities after the boiler is manufactured and stamped is not under Section I.

Contact your Jurisdictional authority for the steps needed to address installation and operation of temporary Boilers and piping systems. Each Jurisdiction should have rules defining this.
My experience has been that the Boiler Rental unit comes with stamped boiler external piping up to the first isolation valve.
Anything beyond this isolation valve is NBEP (non boiler external piping)which allows for the in-service leak test.
It all depends on how your boiler is setup,installed, and the requirements of the jurisdiction.
Typically the jurisdictional inspector will need to come out, review and authorize with a "permit to operate" for temporary installations. Each jurisdiction has their own rules.

So my local jurisdiction can override the code on this?
Thanks again.

If your Jurisdiction enforces boiler and BEP Codes, Any one can specify certification, stamping and hydro:
The spool have to be Mfd & Stamped per Code and can be hydro and stamped at the shop by the Stamp holder who certifies it.
Installation then can be done by a boiler Contractor.
The Jurisdiction can possible allow that arrangement.
(after the first valve is piping not BEP) so the spool will be piping under B31.1
