Are ASME standard cross fittings produced according to ASME standards, and can they be used in European, American, and global ASME standard projects?

The products are produced according to the ASME B16.9 standard, and for stainless steel, MSS SP-43 is also referenced, while small-diameter high-pressure forged crosses follow ASME B16.11. Dimensions use the NPS inch system, wall thickness follows the SCH ASME series, and pressure ratings use the Class pound system. Hydrostatic testing and UT/RT non-destructive testing can be performed before shipment, and EN10204-3.1B material certificates are supported. If the project has specific acceptance requirements, you are welcome to contact us to confirm.

Can ASME Class pound ratings and GB PN pressure ratings be used interchangeably?

ASME Class and GB PN belong to two independent pressure rating systems and cannot be directly mixed. Our ASME crosses are produced according to Class pound pressure bearing, and when selecting models, please confirm according to the pressure rating in the project design documents. If assistance with verification is needed, please contact us.
