Dear Pitch,
For One PSV This is true
But P&ID Tell Me Outlet Of PSV not Piping.
I Know Outlet Of PSV May be 150 # Or Same As Rating Of Inlet OF PSV.
But For 150# Classes according to Bolt Material I have 4 SBOL.
User should be select One Of 150 lb Class.
So , In On Inlet may be i have 2 out let with two different Class With Two Different Bolt Code (SBOL)
For Example If Inlet Of PSV is DD1 Out let of psv may be BD1 Or BD2.
So I Should Create two SPCOM For PSV .. .
Please Help Me
I have been too Confused!!!
The answer is yes.
Create a separate SPECO for each PSV.
In my Specs I give every Instrument a separate SPECO, using the Instrument Name as the speco name.
This helps if changes are made to One item but not other similar items. It means that the user does not have to reselect but can just check that the item is still datacon and clash free.
It is also useful when creating reports.
Dear Pitch
I Have One PSV But Because Of Description of bolt (Material and Design Standard) I Have Five Type of BLTREF In All 150 LB Spec (Because , Each BLTREF Has Unique Commodity(Stock) Code) So I Think I Should Write 5 SPCOM For One PSV In One Spec.
Every PSV is unique and identified by Tag No on the P&ID so you only have one bolting requirement for each.
I suspect you are trying to use one speco to cover all PSVs of the same rating and size combination.
Dimensions are diferent depending upon whether it is spring or pilot operated, What orifice is used, and what manufacturer model No is purchased.
The inlet bolt length may also vary dependant upon the same criteria.
for instance a Crosby Spring operated 150#x300# 4"x6" PSV has 4 different inlet/outlet dimensions depending whether the type chosen is JBS JLT OR JOS, Whether the Orifice is M N or P and what the required flow rate is. That is after consolidating all the variations they provide, (there are at least 23)
And that is just using Spring type from one manufacturer.
If you switch to a different manufacturer you add more possibilities.
Add in Pilot operated valves and there are even more.
So one try to cover all PSVs with one speco will almost certainly never work
Dear Pitch,
Do I Understand what you said ?
I Have 5 Bolt Type For Rating 150 LB .
So For Size Range 2 to 24 Inch I will should Create 5 times SPCO For PSV 2 * 3
PSV 3 * 4 and so on ,That Any Of Them is One Of 5 Types that Bolt Have it.
thanks
Yes I have been Done what you say And I Create MBol From 300# FLANGE TO 150# FLANGE
But I Have 5 BOLT Material TYPE (So I Have 5 SBOL) For 150# SPEC's
For PSV From 300# to 150# I Should Create 5 Type Of MBOL That have Sbra1 From 300 lb and Sbra2 Should be SBOL1 and SBOL2 And SBol3 And Sbol 4 And SBOl 5
SO I Should have 5 Name Of MBOL.
