PRESSURE CONTAINMENT
All Castel products, if submitted to hydrostatic test, guarantee a pressure strength at least
equal to 1,43 x PS in compliance with the Directive 2014/68/EU.
All UL- certified products listed in this catalogue are tested to the declare design pressure,
according to the Standard UL 207.
All UL- certified products listed in this catalogue, if submitted to burst test, guarantee a
pressure strength equal or higher to 5 times the declared design pressure, according to the
Standard UL 207.
CONNECTIONS OF CASTEL PRODUCTS
Castel can supply its products with different connections. Particularly Castel produces its
products either with threaded connections or solder connections. Tables 1 and 2 show the
equivalence between Castel codes and dimensions in inches.
DESCRIPTION OF CONNECTIONS CURRENTLY USED
FOR CASTEL PRODUCTS.
1) THREADED CONNECTIONS
Two different types:
FLARE
Straight threaded connection (according to SAE J513-92; ASME B1.1-89) for junction to a
copper pipe with a suitable flared end, using a right nut (see Table 2).
NPT
Taper threaded connection (according to ASME B1.20.1-92) to joint fittings, valves, safety
valves to vessel or steel pipes.
2) SOLDER CONNECTIONS
Three different types::
ODS (or ODF)
Female solder connection for copper tubes. The indicated size corresponds to the outer
diameter of the copper tube which to joint (see table 1).
F.e.: 1/2” ODS solder connection suitable to receive inside a copper pipe with a 1/2”
outer diameter
ODM
Male solder connection for copper tubes. The indicated size corresponds to the outer diam-
eter of the copper tube which to joint.
F.e.: 1/2” ODM solder connection suitable to joint a copper pipe with a 1/2” mm outer
diameter, by means of an 1/2” female/female copper sleeve.
W
Solder connection for steel pipes. The indicated size corresponds to the external diameter of
the steel pipe which to joint.
F.e.: 76,1 W solder connection suitable to connect a steel pipe with a 76,1 mm external
diameter, by means of butt welding.
