Socketweld Valve End Types

Socketweld Valve End Types

Socketweld Valve End Types

(OP)
I am looking for dimensions on the socketweld and threaded end dimensions for 2" and smaller valves. When they have the class designation of 800 or 1500 and then most vendor catalogs, say the end types are in accordance with ASME B16.11. This standard is on the socketweld and threaded end types of fittings with the designations of 3000, 6000, and 9000. How does the end type from valve match with the end types of fittings?

thanks,

RE: Socketweld Valve End Types

My guess would be 3000 for class 800 and 6000 for class 1500. but this is up to the vendor - connecting it isn't any different as the bore and insert length is the same, just different thickness in the valve body.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Socketweld Valve End Types

This is the reason that we have piping engineers and piping/valve line specifications...

Your plant was probably constructed using a set of piping line specifications that defined system allowable pressures and temsperatures MATCHED WITH Piping materials, schedules and valve types and END TYPES

Process Chemical plants are repeatedly sold and traded like baseball cards ..... Every time they are sold, MBA wisdom dictates that ALL old documentation is thrown away

An example of a piping line specification can be found here:

RE: Socketweld Valve End Types

ASME B16.11 gives socket bore diameter and socket depth, and these dimensions do not change between Class 3000/6000/9000 fittings.

The valve vendor, by saying that the socket weld end is per ASME B16.11, means only that they are giving you a valve body equipped with a socket of bore and depth as specified by ASME B16.11. The other dimensions for the socket weld end (socket wall thickness/hub OD) provided on the valve body forging/casting are whatever the specific valve vendor has deemed appropriate to deliver the valve body pressure rating per the valve design code specified.

RE: Socketweld Valve End Types

ASME B16.34 Table 4 provides the minimum wall thickness required for socket weld ends by pressure class up to NPS 2-1/2.
