What is SAE Code 61?
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.
What is a hydraulic flange?
Hydraulic flange connections are used in the most demanding applications, as they are well suited for high pressure, shock and vibration, especially in larger sizes. Flanges allow easy connection between hose and tube/pipe where flexibility is needed, without adding adapters.
What are flanges and fittings?
A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. Although the word ‘flange’ generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as flanges.
What is a captive flange?
Captive flange fittings simply slip over the flared tube and are connected to the mating flange or other component. Captive flanges are commonly used with MJ-Flange Straight fittings (aka flange adapters), where there is smooth clearance to slide over the fitting and seat on the flange head.
What is a flange port?
The port is simply a flow passage surrounded by four tapped holes that accept the clamping bolts. Typically, the flat-machined surface of the port compresses the O-ring contained in the groove of the flange head when the bolts are tightened.
What is the purpose of a split flange?
It is made up of two interlocking pieces that fit securely together using nuts and bolts or welding it into place. Because it is made of two parts, split flanges are used to reinforce weakened areas of piping, or to add an attachment in places conventional flanges cannot.
Why do hydraulic lines have a square flange?
Square flanges in piping and various systems Square flanges are most beneficial when working with smaller diameter pipes. KAB: This type of flange features a similar design and configuration to SHAB flanges, and will have higher pressure ratings of either 280 kg per square centimeter or 350 kg per square centimeter.
How do I know what flange I have?
You need to find the outer diameter, the inner diameter, the number of bolt holes, bolt hole diameter, and the bolt circle diameter. Bolt circle diameter (B.C.) is one of the most important measurements to make when identifying a flange.
How do you measure PCD flange?
One of the most important measurements is the Pitch Circle Diameter (PCD) which can determine if the flange bolt holes will match each other. Measure across the centre from one side of the internal hole to the opposite side of the hole.
