What does no Skive hose mean?
What does no Skive hose mean?
Skiving refers to removing (or shaving) part of the hydraulic hose cover and/or inner tube prior to attaching hose ends. No-skive means the hose and fittings are designed to work without this step. In other words, hose and fittings come ready to assemble.
What is a skive ferrule?
1 Wire Skive Ferrule – H1100SK1 is generally used for fastening, joining, sealing or reinforcement. They are narrow circular rings made from metal.
Why do hydraulic hoses fail?
Hydraulic hose failure is most commonly caused by abrasion, poor routing, high temperatures, tube erosion, bent hoses near fittings, fluid incompatibility, and improper assembly. If high pressures are involved, there is also a potential risk of physical injury to employees when hoses burst.
What is hydraulic hose?
A hydraulic hose conveys hydraulic fluid to or between hydraulic components. Components include valves, tools, and actuators. Hydraulic hose is usually flexible and reinforced. Hose is often made up of several layers of reinforcement. This is necessary because hydraulic systems operate at high pressures.
What is a hose layline?
The layline indicates hose trade name, size and pressure; SAE, EN or DIN standard; and US MSHA flame resistance compliance. These laylines are used exclusively on MegaSys® hoses. Distinctive design and pressure colour coding makes MegaSys® hoses easy to identify in stock or in service.
What is the purpose of Lay lines on flexible hose?
The layline runs the length of the hose, and contains information about the hose’s most important properties such as size, working pressure, rating, and more.
Can you over crimp a hydraulic hose?
You could crimp it from 1.027 to 1.043. Anywhere within that range, the hose is still valid, but you don’t know where you’re at. You either risk over-crimping and restricting flow or damaging the braiding on the hose, or you risk it not being crimped enough and blowing off a hose end.
How do I know if my hose is damaged?
You Need to Visually Inspect the Hose Check the cover for signs of cracking, cutting or any exposure of reinforcements. Stiffness, hardness, heat cracks and damages or a charred hose. Corroded or cracked fittings. Leaks around the fitting and through the hose.
How often should hydraulic hoses be changed?
Hydraulic hoses should last between one and two years with many lasting up to ten years, so if the hoses on your equipment are failing in less than two years, then there are external factors that are reducing their life.
What does hose ID mean?
Inner diameter (I.D.) is the span of the empty space in a circular hose cross-section that affects the flow velocity of the fluid within the hose. A hose with an oversized I.D. will result in sluggish system performance, while an undersized I.D. can cause excessive pressure drops, leaks, and system damage.
How do you identify a hydraulic hose?
The best way to check is to measure the taper angle or screw a known fitting into the hose. You can also check thread pitch and diameters to confirm things. Identify the thread as BSP, Metric or JIC flare etc. Identify the thread size.
