What is the difference between code 61 and 62 flanges?

What is the difference between code 61 and 62 flanges?

SAE J518 flanges come in two pressure classes. The standard series, Code 61, which goes to 3,000 psi and the high pressure series, Code 62, where all the sizes are rated at 6,000 psi. SAE J518 is interchangeable with ISO 6141, DIN 20066 and JIS B 8363, except for the bolt sizes.

What is a code 62 flange?

High pressure or Code 62 Flanges are all rated for 6,000 psi maximum working pressure. Caterpillar style flanges are designed and used only on Caterpillar equipment. Caterpillar Flanges are identical to Code 62 dimensionally except it has a thicker dimension C.

How do you measure a 4 bolt flange?

MEASURING A STANDARD FLANGE Measure across the centre from one side of the internal hole to the opposite side of the hole. Measure across the centre from the external edge to the other external edge of the flange. Measure from centre of the bolt hole to centre of the opposite bolt hole.

What is SAE standard?

Standards from SAE International are used to advance mobility engineering throughout the world. The SAE Technical Standards Development Program is now-and has been for nearly a century-among the organization’s primary provisions to those mobility industries it serves: aerospace, automotive, and commercial vehicle.

Are JIC and SAE fittings the same?

JIC fittings are dimensionally identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size.

How do you read a flange size?

Use a ruler or measuring tape to find the diameter of your nipple (the horizontal width across it) in millimeters (1 cm = 10mm). Measure the nipple alone, do not include the areola, which is the outer edge around your nipple. Add 4 mm to this measurement, so if your nipple is 20 mm across, your flange size is 24 mm.
