SELECTING THE RIGHT HYDRAULIC HOSE
TCH has a 40-year track record of helping companies with their most demanding hose assembly needs. Let’s just say we know a thing or two when it comes to selecting the right, high quality hydraulic hose for you.
Hydraulic hose is designed to provide the pressure an industrial machine needs to do is job.
When it comes to selecting the proper hydraulic hose, size, temperature, application, media, end connections, and details of your system are common considerations to make sure you get the right hose (refer to our stamped article for more information).
WHAT ARE HYDRAULIC HOSES USED FOR?
A hydraulic hose transfers pressure in a system that is doing the work, such as lifting dirt, moving a loader, or splitting logs.
WHAT SIZES DO HYDRAULIC HOSES COME IN?
We have customers coming into our shop needing a hydraulic line replaced quite frequently. In these situations. We typically see lines that are 3/8″ and 1/2″, but hydraulic hoses are available from 1/4″ all the way up to 2”.
As the I.D. (inside diameter) of hydraulic hose gets larger, you’ll start to notice a drop in PSI ratings. Take a look at the pressure ratings compared to I.D. for Danfoss Weatherhead’s H280-series hose:
REMEMBER: These psi ratings aren’t consistent between every brand of hose, but it goes to show pretty clearly how you will lose pressure as you increase the I.D. of your hydraulic hose systems.
WHAT ARE THE MOST COMMON HYDRAULIC HOSE FITTINGS?
JIC (37° seat)
NPT (national pipe thread)
O-Ring Face Seal
Code 61 & 62 Flanges
HOW DO I TAKE HYDRAULIC HOSES OFF?
NAHAD, The Association for Hose and Accessories Distribution, offers us insight into the proper methods of removing hydraulic hoses from an assembly.
Bearing in mind that safety should be a primary concern when removing a hydraulic hose from your system, most fittings are as simple as throwing a wrench on and loosening the end connection. Always remember to have your system depressurized, and you can save yourself a lot of trouble by having a reservoir ready for excess fluid and caps and plugs to seal off loose hoses.
Let’s review some common safety considerations:
Due to certain medias’ ability to permeate through hoses, your hose should always be used (and removed) in well-ventilated areas.
Hydraulic hoses run at very high pressures and—if it bursts—can penetrate skin and enter a human body. Fluid injections can cause severe damage and loss of limbs.
If a hydraulic hose is under pressure and comes apart, the loose end can whip with strong force, and the fittings can even be blown off at high speeds. Consider using guards or restraints and remember to depressurize your system before removing a hose.
FIRE AND EXPLOSIONS FROM CONVEYED FLUIDS
As fluid passes through a hose, it can generate static electricity, resulting in static-electric discharge. The sparks generated can ignite systems or fluids in the surrounding atmosphere. You can use hose that is non-conductive in specific applications where this can be an issue.
BURNS FROM CONVEYED FLUIDS
Certain chemicals, or fluids that reach excessive temperatures, can burn human skin. Again, consider guards and shields to prevent injury.
Most hoses are conductive with metal fittings. Electric shock can occur when a hose assembly conducts electricity to a person.
