Section 9
Flanges are commonly used to connect large sizes of hose and tubing. An
O-ring in the flange head seals on a smooth face, female port. The male flange
head and female port are held in place with two clamp halves and four bolts.
Flanges conform to SAE J518 standard and are identified as Code 61 or the
“
standard series” and Code 62 or “high pressure series”. The two flanges are not
interchangeable as Code 61 is used in applications of up to 5,000 psi working
pressure. Code 62 is designed for 6,000 psi working pressure. Code 61 and Code
62
are dimensionally different. Specifics on Code 61 and Code 62 flanges are
found in the following charts.
Determine Flange Size
Method 1:
Measure the port hole inside diameter.(ID).
Method 2:
Measure the “A” dimension on the flange, which is the
longest bolt hole spacing from center-to-center.
Assembly Procedure
1.
Clean all mating services.
2.
Replace O-ring. Lubricate before installation.
3.
Partially tighten each bolt in rotation until all are fully tightened
to the recommended torque value listed in the Appendix.
