Welding Requirments for 2"Hydraulic pipe in Ontario
Welding Requirments for 2"Hydraulic pipe in Ontario
(OP)
Hi, Could someone please point me in the right direction...
I have some 2" Sch 160 hydraulic pipe (B/X42 s-tested)that I need to weld a new T onto.
Q- I know I should have a pressure ticketed welder...but do I have to? (our welder had a ticket....but is not current)
Q2- What codes would govern a repair like this?
It is a Hydraulic system used in our energy system....BUT it is exempt from the Ontario Boiler and Pressure vessel Act. (Boiler branch confimed this, and they were of little help)
Thanks
Jeff

Actually, the Boiler Branch does apply for any pressurized system above 14.2 psig or one atmosphere AND application is designated for commercial use or in the public domain. Your post regarding non conformance to this body is probably because they consider application as private.

Here is what the senior Technical Inspector from the Ontario Boiler branch said about Ontario's Boiler and pressure vessels Act. (regulation)
****************
The Regulation states:
(2) This Regulation does not apply to,
(2)(g) a pressure vessel that is used exclusively for hydraulic purposes at a temperature no greater than 150ºF (65ºC);
If the system is completely hydraulic (no gas entrained in the system) operating at 150F or less (the owner must decide this) then it is exempt. It is then the owners responsibility to maintain it.
If our Regulation does not apply, then the Occupational Health and Safety Regulations would place the onus on the owner to ensure that the equipment is maintained and operated safely.
*********************
He suggested that maybe I look at ASME B31.1 or B31.3.
I was hoping someone could tell me what code would be used for the design and repair of this pipe with fittings.
Pipe-ASTM/ASME A/SA-106 GB (seemless pipe rated at 3000PSI)
Fittings are 2" 3000PSI ....(I belive the are forged steel)
thanks again

Pipe Sch.80 is compatible with fitting Class 3000. What is the design condition of your piping system?

We deliver steam as if your life depends on it.

It would appear, from this, that it was NEVER the intention of the pressure piping code people to cover hydraulics.
