Introducing our premier hydraulic cylinder component, the Precision OD 40-550mm Hydraulic Pipe, crafted meticulously to serve the demanding specifications of modern hydraulic systems. Engineered using the robust ST52 E355 grade steel, this honed tube is the epitome of strength and precision, ensuring unmatched durability and performance in any hydraulic application.

With an outer diameter meticulously controlled between 40mm and 550mm, our hydraulic pipe is tailored to accommodate a diverse range of hydraulic functions, from small machinery to large industrial equipment. The H8 tolerance honing of the inner surface guarantees a superior finish with extremely precise internal dimensions, ensuring efficient, smooth operation and reduced wear on hydraulic cylinder components.

The steel grade ST52 E355 used in this hydraulic pipe is renowned for its high yield and tensile strength, as well as its notable impact resistance, making it an ideal choice for high-stress applications. It's not just about strength, though; the steel's excellent machinability and weldability ensure that it can be easily integrated into various hydraulic systems without compromising the integrity of the assembly.

This hydraulic tube's corrosion resistance is enhanced through careful selection of materials and manufacturing processes, allowing it to withstand challenging environments and prolonging its service life. This feature is particularly beneficial in industries where exposure to harsh conditions is common, such as in construction, mining, and agriculture.

Moreover, the honed interior surface of the tube minimizes fluid turbulence and enhances the flow of hydraulic fluid, which significantly improves the efficiency of the hydraulic system. This smooth interior not only aids in maintaining consistent pressure but also reduces the risk of fluid leakage, ensuring operational reliability and safety.

Our Precision OD 40-550mm Hydraulic Pipe is a testament to our commitment to quality and innovation. Each tube undergoes rigorous testing and quality control measures to meet and exceed industry standards, providing you with a reliable and high-performance product that enhances the functionality and longevity of your hydraulic systems.

Whether you are upgrading existing equipment or designing new machinery, our hydraulic cylinder tube is the perfect choice for any application that demands high precision and durability. With its superior properties and adaptability, this honed tube is poised to be an integral component in your hydraulic assembly, contributing to more efficient and robust operations.

 
 
 
Product Description

HONED TUBE / HYDRAULIC CYLINDER TUBE BRIEF INTRODUCTION

Honed tube is well known as hydraulic cylinder tube in many industries. This is because honed tube is ready to use for hydraulic cylinder applications without further ID processing. This product is the most important materials for manufacturing hydraulic cylinders. And as this kind of tubing is usually honed in tube inside diameter, it is known as honed ID tubing also.
 
Our factory manufactures & supplies honed tube, hydraulic cylinder tubes for nearly 15 years, here below is the details of our product of honed tubes.
 
OVERVIEW OF OUR HONED TUBES
PRODUCT NAME: HONED TUBE
ALSO KNOWN AS PRODUCT NAME: HONED TUBING / CYLINDER TUBE / CYLINDER TUBING / HONED CYLINDER TUBE / HYDRAULIC CYLINDER TUBING / HONED ID TUBING
 
Honed tube for hydraulic cylinder is made of our factory's own cold drawn seamless tube (CDS tube), by honing process or Skiving & Roller Burnishing process.
 
PRODUCT STANDARD:
Our honed hydraulic cylinder tube is usually produced according to norms as ASTM A513, DIN 2391, DIN 1630, DIN 1629, EN10305-1, EN 10216-2, A 519, etc on customer's request.
 
SIZE RANGE:
We manufacture honed tubes in metric dimensions and imperial dimensions, size range from I.D 30 mm to I.D 500 mm (1.5″ - 20″), Wall thickness 3 - 50 mm (1/8″ - 2″)

As one of the leading hydraulic cylinder honed tube suppliers, our factory manufactures the honed pipes using our factory's "Suitable To Hone" Steel Cold Drawn Seamless Tubes (CDS tubes). In order to produce extremely precise ID dimensions and smoothly ID surface, the honing process involves using abrasive polishing stones and abrasive paper to remove small amounts of material.
 
Besides the honing process, we also use the SRB process (skiving and roller burnishing) to produce honed tubing.

Honed tube for hydraulic cylinder is ready to use for producing or repairing hydraulic cylinders without any further ID
processing.

HOW TO PURCHASE HYDRAULIC CYLINDER TUBE FROM US?
 
As one of the leading hydraulic cylinder honed tube manufacturers and suppliers in China, we sell hydraulic honed tubing to customers and provide full range of technical support. Please contact us through below methods for more information.
