Common Causes of Damage to Hydraulic Metal Hoses

Metal hoses, widely used in industries such as machinery, chemicals, petroleum, metallurgy, and food, are primarily constructed from austenitic stainless steel. This material ensures excellent temperature and corrosion resistance, allowing the hoses to withstand harsh environments when the appropriate stainless steel grade is selected for specific media. However, despite their durability, hydraulic metal hoses can still suffer premature damage due to several factors. Below are the key reasons behind their failure and recommendations to extend their service life. 1. Detachment of the Externa...

VCR vs. Compression Fittingss: Key Differences for Ultra-Clean and Specialized Piping Systems

Introduction In ultra-clean or specialized piping installations, selecting the right connection method is critical to ensuring system integrity, safety, and performance. Among the most widely used solutions are VCR fittings and compression (ferrule) fittings, both often constructed from stainless steel. Hainar Hydraulics a leader in precision fluid system components, breaks down the distinctions between these two connection types to guide engineers and procurement professionals in making informed decisions. 1. Working Principles VCR Fittings VCR (Vacuum Coupling Radiation) fittings are a ty...

*Selecting the Right Hydraulic Tubing: A Critical Step for System Safety and Performance

In industrial hydraulic systems, the correct selection of hard tubing is not merely a technical detail—it is a vital safeguard against catastrophic failures. Leaks, bursts, and hazardous fluid discharge caused by improper tubing choices can lead to severe injuries, environmental damage, and costly downtime. To ensure operational reliability and safety, engineers and system designers must prioritize precise tubing selection based on application-specific requirements.  Key Factors in Hydraulic Tubing Selection When specifying hard tubing for hydraulic applications, the following factors deman...
