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.

Materials of our chrome plated tubes

Our chrome plated pipes are produced from first class quality carbon steel seamless tubes or hollow bar. The steel grades available in SAE 1020, SAE 1026, SAE1045, St 52, St37.4 and so on.

Size Range

Our chrome plated tubes / chrome plated hollow bar is available in size range of O.D: 15 mm to 609 mm, with W.T 1 mm to 40 mm.

We also produce and supply imperial size chrome plated pipes.

Length

Our chrome plated tubes / pipes can be supplied with length up to 14 meters, fixed length and random length are available on customers’ request.

Chrome plated tube outside diameter size tolerance

The Outside diameter tolerance of our chrome plate tube can be as precise as ISO h7, and we can supply with other tolerance on customers’ request.

Surface of Chrome plate tube / chrome plated hollow bar
