SAE FLANGE BRIEF INTRODUCTION

SAE Flange is a series of high pressure hydraulic flange which is designed and produced according to standards ISO 6162-1 or ISO 6162-2, and it also conforms to American standard SAE J 518 C. The SAE flanges are widely used on oil hydraulic systems in various industrial areas (such as mobile offshore marine industries, hydraulic equipment, Construction machinery, Ship building, machine tools, and so on), and where there is passage of oil under pressure.

Sizes:

There are two series of SAE Flanges, which are SAE code 61 (class 3000 psi series) designed to ISO 6162-1, and SAE code 62 (class 6000 psi series) designed to ISO 6162-2. 
– For code 61 flanges (SAE 3000#  flange), we can manufacture and supply with sizes between DN10 (3/8″) and DN125 (5″). 
– For code 62 flanges (SAE 6000# flange), we can manufacture and supply with sizes between DN10 (3/8″) and DN80 (3″)

Materials:

Our SAE flanges are made from normalized forgings, and there are mainly of material carbon steel (ST52, SAE1020) and stainless steel SS316L, SS304L.

Working Pressure:

SAE Code 61 flanges and SAE code 62 flanges have different working pressure range as below.
– Code 61 flange (3000 psi SAE flange): the pressure range is from 34 bar to 345 bar;
– Code 62 flange (6000 psi SAE flange): the pressure range is from 200 bar to 414 bar;

The working pressure of the SAE flanges and connected equipment combinations may be different from each other. The working pressure of the hydraulic flanges also are determined by the bolts, O-ring used. For example, the SAE flanges with bolt grade 10.9 can bear higher working pressure than the SAE flanges with bolt grade 8.8. Also the SAE flange connected with a pipe of higher strength material with thicker wall thickness can bear higher pressure. The working pressure of the system is determined by the working pressure of each connection parts.
