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.

Chrome-plated-tube, chrome plated hollow bar

Materials of DIN 3567 metal tube clamps

Carbon steels, 304 stainless steels, 316 stainless steel, 316Ti stainless steel  DIN 3567 pipe clamps are available.Compare galvanized carbon steel pipe clamps to stainless steel pipe clamps (304/316/316Ti), stainless steel pipe clamps have better anti-corrosion performance, so it is more commonly used in marine environment. For DIN 3567 carbon steel pipe clamps, usually the surface condition is galvanized (zinc coated) or hot dip galvanized (hot dip zinc), You can easily distinguish them by surface condition Continue reading →

How to choose, process and install hydraulic tubes properly?

Need hydraulic tubes? please contact: 

Hydraulic tubing manufacturer

How to choose, process, and install hydraulic tubes properly, in order to make the hydraulic line system work more energy-efficient, reliable, and have a longer life? This has become an important issue for hydraulic technologies. As one of the leading China hydraulic tube manufacturer and supplier, our company Younglee Metal specializes in manufacturing stainless steel hydraulic tubing and carbon steel hydraulic tubing for many years, and has many years experience of hydraulic tube related technology and research, we solved the hydraulic tube related technical issues for many customers, and provided production and technical services to them.

This article will briefly describe the hydraulic pipe selection, processing, installation, etc., with hope to help the customers in the hydraulic system industry who are in need.

Choose the right material and size of hydraulic tubes

The hydraulic tubes should be selected according to the system pressure, flow and application environment. Must pay attention to the strength of the tubing whether is enough, whether the pipe diameter and the wall thickness meet the system requirements, and the inner wall of the selected steel pipe must be smooth, non-corrosive, non-oxidized skin, no clips and other defects. If any of the following problems is found on the hydraulic tube, it cannot be used:

  1. the inner and outer walls of the hydraulic pipe have been heavily rusted;
  2. the scratch depth of the pipe body is more than 10% of the wall thickness;
  3. the surface of the pipe body is recessed to more than 20% of the pipe diameter;
  4. the wall thickness of the pipe section is uneven and the ellipticity is obvious.

In applications of medium and high pressure hydraulic systems, the seamless steel tubes are generally used, because they have the advantages as high strength, low price, and easy leak-free connection, it is widely used in hydraulic systems.

 

Stainless steel hydraulic tubes and hydraulic pipes

Ordinary hydraulic systems often use cold drawn low carbon steel tubes, because carbon steel hydraulic tubing can be reliably welded to various standard pipe fittings. And for applications where there is corrosion resistance is required, such as Hydraulic servo system, often use ordinary stainless steel seamless pipe, stainless hydraulic tubes are with corrosion resistance, smooth inner and outer surfaces, accurate size.

Regarding how to choose the right outside diameter and the wall thickness of the hydraulic tubes, we will talk in another blog article later.

Hydraulic Tubes processing, like Cutting, bending, welding

 

The processing of pipes mainly includes cutting, bending, welding and so on. The quality of the pipe processing has a great influence on the parameters of the pipeline system, and it is related to the reliable operation of the hydraulic system. Therefore, scientific and reasonable processing methods must be used to ensure the quality of processing. Continue reading →
