What are the Pressure Ratings for different SAE Flanges?

Sae flange, Code 61 flange, Code_62_flange Younglee manufacturer

SAE Flanges are usually forged flanges designed to standard SAE J518C and ISO 6162. They are mostly used in hydraulic systems and high pressure applications. So what are the working pressures for different sizes of SAE hydraulic flanges?

There are two different series divided by the pressure ratings, which are:

  • Pressure 3000 psi series

SAE Flanges of 3000 psi series usually are known as code 61 flanges, and sometimes they are called SAE 3000 flanges or SAE flange class 3000.

3000 psi SAE flanges are designed according to standard ISO 6162-1.

Here below is the chart shows the specific working pressure of the different sizes of SAE 3000 flanges:

Chrome plated tube / Chrome plated pipe for hydraulic piston rod

Chrome plated tube general introduction

Chrome plated tube, chrome plated steel bar and honed cylinder tube are the main materials for manufacturing hydraulic cylinders. As hydraulic cylinders are widely used in various kinds of machines and equipment, these three products are widely used in modern industries.

Chrome plated tube is known as chrome plated hollow bar or chrome plated hollow steel in some industries. This product usually is made of seamless steel tubes or seamless hollow bar, by precision polishing on outside diameter and with a certain thickness of chrome plated layer on outside diameter, so they are called chrome plated OD tube also.

The chrome plated surface provides excellent wear and corrosion resistant performance of the tube. Chrome plated steel tubing has an excellent durability and helps reducing friction. Chrome plated pipe is mostly used as hydraulic piston rods in order to have a lighter hydraulic cylinder. And chrome plated OD tube also can be utilized for applications where precision outside diameter or high smooth outside surface is  required. Chrome plated OD tubes can be supplied with honed inside surface for telescoping hydraulic cylinder applications too.
