Description:
A hydraulic SAE socket weld flange is a type of socket weld pipe flange manufactured in accordance with ISO 6162 and SAE J518 standards. There are two pressure series for hydraulic SAE Socket Weld Flange: 3000 psi and 6000 psi.
Smaller diameters of high-pressure pipe can often use socket weld pipe flanges. The welded pipe flanges can be connected by inserting the pipe into the socket end of the flange and welding around the top.
For distributor replenishment or OEM production, send your part numbers, flange code and size, pipe dimensions, material requirements, and quantities by item. Attach a drawing where socket dimensions or mating-interface details need confirmation.
Features and Benefits:
Categories: SAE, Flange, Code 62, Code61, Carbon steel,
Use the dimensional drawing to identify each table symbol. Check the flange interface and weld socket separately: nominal flange size does not define the pipe outside diameter, wall thickness, or socket fit.
Where several part numbers share a nominal flange size, compare their socket and fastener details before selection. Confirm whether the order requires metric or inch-series fasteners and the corresponding mating-port threads.

Code 61 and Code 62 use different interface dimensions. Do not substitute one series for the other based only on nominal size or a higher pressure-series designation.
Check the mating equipment drawing for the bolt pattern, interface dimensions, bolt specification, and seal arrangement. Then verify the selected flange’s rated pressure, temperature limits, material, and pipe connection.
For an existing installation, send the equipment reference or a dimensioned drawing. Photographs can support identification, but they do not replace measurements or the applicable specification.
Review related flange components by interface series, size, sealing-face design, and mounting arrangement. Products shown together are not automatically compatible with one another.
For a complete-set inquiry, identify the required flange, mating component, O-ring, bolts, and any other specified hardware.
