Summary of SAE FlangesPosted by Holck Flindt on February 13th, 2021 What usually are SAE Flanges? Issue question confounds an individual, this is the right place to obtain answers. Introduction:
HIGHLY RESISTANT TO WEATHER CHANGES Flanges is a selection of hydraulic flange that is made within accordance to HIGHLY RESISTANT TO WEATHER CHANGES J518 standards. The particular acronym SAE appears for Society of Automotive Engineers. These kinds of flanges are used on oil hydraulic systems in several fields (shipbuilding, cell phone hydraulic equipment, equipment tools, earth shifting machines, and so forth.. ) and that result in passage of oil under pressure.
Material:
Flanges are made from normalized forgings and are usually associated with two kinds associated with material, steel ST52. 3 and stainless steel AISI SS316L.
Sizes:
SAE Flanges come in 2 series, code 61 (3000 series) plus code 62 (6000 series). For program code 61 (3000# series), they are obtainable in all minimal sizes between DN10 (3/8") and DN125 (5"). For code 62 (6000# series), they are obtainable in all small sizes between DN10 (3/8") and DN80 (3")
Working Strain:
The standard stress ranges from thirty four to 345 bar for code 61 (3000 series) plus 200 to 414 bar for program code 62 (6000 series). Please take take note that the stress information of the particular flange and attached equipment combinations may possibly vary from each and every other. For illustration: if the pipe connected to the flange has a lower working pressure, that will result in a great overall lower functioning pressure of the system. Therefore, please consider the lowest stress as the maximum working pressure of this specific combination.
How SAE Flanges work:
A new complete set comprises of a flat part flange and a good o-ring side flange. The o-ring part flange contains a new groove seat to place a plastic o-ring (normally manufactured from NBR material). The complete set forms the seal between a set surface and o-ring held in the recessed circular grooved in the other half. Tightening
MS Flange mounting bolts draws the a couple of halves together plus compresses the O-ring.
For this reason usage regarding the o-ring, flanges with o-rings has an advantage over metal to metal flanges as all-metal flanges are more vulnerable to leakage since they should be stiffened to a increased, yet narrower rpm range. This makes metal to steel flanges more susceptible to strip threads or crack.
An entire set of flange is tightened making use of socket head cover screws & spring washers according to recommended torque. The particular screw lengths are usually usually shorter compared to overall SAE flanges length but this is normal in compliance to SAE J518 standard. Also, as per SAE J518, there are no requirements for hex nuts for protecting the flanges.
Configurations of SAE Flanges:
Commonly used connection types consist of: Weld In/ Socket Weld, Weld On/ Butt Welds, NPT Threaded, BSP Threaded, Blind Flanges, Split Flanges.
After request, flanges could be supplied total with screws, washers and NBR/Viton o-rings.
