Younglee’s pipe clamp factory is one of the first class quality China manufacture of SAE Flanges which including SAE weld flanges.
Main series:
SAE butt weld flanges are divided into two series according to designed standard and working pressure as below, which are used for different pressure rating hydraulic tubing connectors.
- 3000 PSI standard pressure series according to ISO 6162-1, also known as code 61 flanges
- 6000 PSI high pressure series according to ISO 6162-2, also known as code 62 butt weld flanges
Both of the above series are conform to standard SAE J518C also.
Materials and Surface conditions:
Please refer to the product introduction of SAE weld flanges for the materials and surface conditions of SAE butt weld flanges, because it is the sub-category. For stainless steel hydraulic tubing connecting, usually we use stainless steel SAE flanges.
