This instruction is made by Younglee Metal Products Co.,Ltd, complied and implemented by quality department of its SAE Flange factory.
This instruction is intended to strengthen the quality management of flanges, making the quality inspection be processize, standardization, and improve the quality control level. Flanges should meet our factory inspection and testing standards, in addition to the implementation of the contract technical requirements. If there is a conflict between the requirements of the contract and this requirement, it shall perform the higher standard as required.
SAE flanges / hydraulic SAE flanges are the main product of Younglee group’s factory also. The products are made according to SAE J 518 C and ISO 6162-1/2, and they are for safe and leak-free flange connections. And now we are one of the first class quality SAE flanges manufacturer in China.
All the above products of SAE flanges come in two main series:
3000 psi standard pressure series designed according to standard ISO 6162-1, SAE 3000 flange is also known as code 61 flanges;
6000 psi high pressure series designed according to standard ISO 6162-2, SAE 6000 flanges are also known as code 62 flanges;
SAE hydraulic flange Pressure rating and working pressure:
There are mainly two different pressure ratings for the SAE hydraulic flanges as below.
Standard pressure series SAE class 3000 flanges: pressure rating 3000 psi with working pressure between 35 bar to 350 bar.
High pressure series SAE class 6000 flanges: pressure rating 6000 psi with working pressure maximum 400 bar.
SAE Flange Size Range:
As the professional hydraulic SAE flange manufacturers, Younglee can manufacture and supply full size range of SAE 3000 flanges and SAE 6000 flanges.
For class 3000 psi standard pressure series: nominal sizes DN 13 (1/2″) – DN 127 (5″)
For class 6000 psi standard pressure series: nominal sizes DN 13 (1/2″) – DN 76(3″)
Materials of SAE code 61/ code 62 flanges:
Carbon steel SAE flanges
Stainless steel SAE flanges: 304, 316, 316L, 316Ti, or equivalent EN/DIN stainless steel grade 1.4301, 1.4401, 1.4404, 1.4571; other grades of stainless steel SAE flanges are available on customers’ request.
Younglee SAE Flanges are used as one of the most safe and leak free pipe and tube connectors, widely applied in various hydraulic systems in the following fields of industry:
Injection Moulding Machinery
Aluminium Die-Casting Machinery
Lifting and Material Handling Equipment
As the first class China flange suppliers, we had supplied our products of SAE Flanges to many customers in China market and oversea markets, we had gained very good reputation in these markets.
SAE Socket Weld Flanges are one of the main types of SAE wled flanges, which are designed and manufactured according to standard ISO 6162-1/ ISO 6162-2. Products are conform to standard SAE J518 as well.
SAE screw-in flanges (SAE threaded flanges) are the main products of Younglee’s SAE flange products group. This product is designed according to ISO 6162-1/-2, and conform to SAE J518C, and comes in two main varieties according to the different thread types:
SAE BSPP threaded flanges are the SAE threaded flanges with BSPP type thread. As a sub variety, this product followed all the descriptions of SAE threaded flanges. To find information of materials, working pressure, surface treatments and size range, please refer to SAE threaded flanges.
SAE NPT threaded flanges are the SAE threaded flanges with NPT type thread. As a sub variety, this product followed all the descriptions of SAE threaded flanges, including materials, working pressure, surface treatment and size range, and so on.
Except the difference of thread type, the other specifications and technical parameters of SAE NPT thread flanges are the same with BSPP thread flanges.
So to find the sizes, working pressure and dimensions of SAE NPT thread flanges, please refer to SAE BSPP thread flanges.
Split SAE flanges are one of the common products of SAE flanges. Younglee manufactures and supplies best China sae split flanges in a wide range of sizes in carbon steels and stainless steels.
Usually two halves (a pair) of SAE split flange halves make up A split flange. There are two main series of SAE split flange halves, which are standard pressure series (3000psi), this series is also known as code 61 SAE split flange, it is also called light duty split sae flange in some areas, It is designed and manufactured according to ISO 6162-1;
and the other series is high pressure series (6000psi) split flanges designed according to ISO 6162-2, this type is also known as code 62 SAE split flange, and it is called heavy duty split sae flange halves in some areas.
Our product of SAE split flanges also conform to SAE J 518 C.
Materials of SAE split flange:
As one of the main manufacturer and supplier of SAE flanges in China, our factory can produce and supplier sae split flange in full range of materials.
