Machine bolts

how can I choose the bolt type (stud or mach)
flanges have btyp BOLT and flange valves have btyp MACH ,Waffervalves have btyp STUD.
so long is ok, but when I have flange to flange then I get automaticly stud bolt !!???
though I want mach bolt, any suggestions????

Hi babo,

try to set in Bolt.Spec the default to MACH.

First of all a few questions.

1. Are you saying that the piping spec specifies Machine Bolts for all flanged connections except wafer valves?
2. Does the wafer valve require STUDS or STUDBOLTS

3. What BTYPE is set in the BLTREF you have used for
    a) Flange
    b) Flanged Valve
    c) Wafer Valve

hello pitch,

gud day!

Just a clarification.
In new bolting method, do we need to set the BLTREF of flanges, flanged valves, wafer valves etc? I'm used to setting BLTREFs only to bolt spcos.

Normally i use the same BLTREFs(SBOLT) for flange-gask-flange and flange-wafer type-flange. But for special occasions like addition bolt length for certain assembly, i should create diff SBOLT. Is setting the BLTREFs of flange type components(wafer valve..etc) the solution to select diff. bolt length when generated in isodraft?

Thanks pitch.

sorry pitch.

*But for special occasions like diff bolt length for certain assembly using normal flange, i should create diff SBOLT to cater diff xtralength. Is setting the BLTREFs of flange type components(wafer valve..etc) the solution to select diff.  SBOLT when generated in isodraft?

ex.
FOR FLANGE AND VALVE SPEC:

TYPE      NAME                                      PBOR1 PBOR2    .... BLTREF

FLAN     */FLSW:XXX/FLSW/0015/0000  15.00   0.00       .... /BN-1/2

VALV     */BAFF:XXX/BAFF/0050/0000    50.00   0.00      .... /BN_LONGER-1/2

FOR BOLT SPEC:

TYPE      NAME                                     BDIA                .... BLTREF

BOLT      */STBT:XXX/STBT/0013/0000    13                .... /BN-1/2



if i will create a flange-gask-valve-gask-flange assembly using the above sprefs, will it select the SBOL --> /BN_LONGER-1/2 for this assembly?
I just want to clarify how to select diff SBOL using the same flange above together with diff. kinds of flanged components since the setting of BLTREF is already done in BOLT spco.

tanx pitch.

With "new Bolting" you do not set the BLTREF in the Pipe Spec.
Isodraft uses the Boltset assigned to the component SCOM

tanx u very much pitch..

another question.

in flange-wafer type comp-flange assembly, normally we don't set the boltset for wafer type component so the answers for selection of bolt spco can only be found on the flange boltsets.  i want to select a diff SBOL for the assembly with wafer type component because i need a longer xtralength(client req.). how do you handle this assembly to select a different SBOL(not the SBOL used in flan-gask-flan)?
using BSEL is not a good option because there are lots of wafer type components to be used.
