High Pressure Hose Thermoplastic TH Series

Application

Thermoplastic Hose for Industrial Fluid Applications (SAE J517 100 7R/8R) thermoplastic hose is designed to handle a wide range of industrial fluids. The use of thermoplastic materials for the tube, reinforcement, and cover ensures performance capabilities beyond conventional wire-reinforced rubber hose.

Nylon Core

The Nylon core tube is free of manufacturing soapstone or grit and is compatible with most chemicals, solvents, hydraulic oils, and synthetic fluids. The synthetic fiber reinforcement, unlike wire reinforcement, resists fatigue caused by flexing and rugged handling. Thermoplastic hose is also 60% lighter in weight than conventional rubber hoses with wire reinforcement. The rugged polyurethane cover provides for abrasion resistance and longer service life over comparable rubber hose. Unlike rubber hose which cures on the shelf, thermoplastic hose has an unlimited shelf life and is resistant to UV light and ozone. The SAE J517 100 7R hose is available in pressures to 2750 psig (190 bar), and the SAE J517 100 8R hose is available in pressures to 5000 psig (345 bar). Both hoses can be used in continuous service to temperatures of 200°F (93°C).

Hose and pipe installation

Tubing must be properly support and securely clamp, to avoid vibration and movement, threading swarf and cutting burrs must be carefully remove to stop them from breaking loose and being flushed into the hydraulic system.
Although hoses are cover with a tough outer layer to reinforce and protect the inner layers, this outer layer should not be abrade or damage. Hose must bend in the same plane as the connection to which it is attach, to prevent twisting. The house appearance does not show whether the recommend minimum bend radius has been exceed; the hose reinforcement determines this radius. It is best to check the manufacturer’s specifications prior to installation (fig)

End Connection

End fittings are manufactured to suit the standard thread forms and flanges used throughout the world. 
They are further classified as:
* re-usable (subject to serviceability); and
* permanently attached, which is further divide into
– crimp type, where a tubular sheet steel ferrule fixe to the insert is deform to crimp the hose between the ferrule and the insert; and
– pallet-swage type, where a separate, machine ferrule is swage onto the hose end to grip the hose between the ferrule and the insert.

Provide that the fittings are correctly attach, it is generally accept and proven by test results that re-usable as well as permanently attach hose end fittings will outlast the service life of the hose. 

Hydraulic Hoses 

Hydraulic hose for industrial and mobile use is manufactured to conform to S. A. E. specifications. The two types of hydraulic hose most commonly used are single wire braid (S. A. E. 100 R1) and double wire braid (S. A. E.100 R2), which differ in their pressure ratings. Each type is made in two versions with different thicknesses of the
outer elastomeric layer. They are:
• skive type, with a thick outer layer which must be skived to expose the wire braid prior to attaching the end fitting, e. g. S. A. E. 100 R2A; and
• non-skive type, with a thin outer layer which is not removed prior to attaching the end fitting, e. g. S. A. E.100 R1AT.

End Connection Sleeve and O-ring

Flare fittings are still widely used, but have lost some ground to compression fittings and O-ring seal fittings. in flare fittings leak tightness is achieve by squeezing the flare end of the pipe against a sealing cone as the compression ring or nut is tighten.
Compression (sleeve) fittings seal by wedging the sleeve onto the pipe and forcing it partly into the pipe surface, so that a slight deformation occurs (fig.). Squareness of the pipe end is not as critical as with flare fittings, and absolute tightness can be guaranteed if tightening procedures and specifications are adhered to.
O-ring seal fittings hold the tube by means of a sleeve wedge onto the tube by the nut (fig). The O-ring provides an absolute seal against leakage. Special O-rings must be used for non-flammable synthetic hydraulic fluids.

Hose selection and rating

Since peak or surge pressure spikes often reach 200 per cent or more of the calculated and adjusted maxi-mum system pressure, hoses and pipes should be select to withstand such pressure peaks. Three pressure ratings are usually given by the manufacturer:  The recommend maximum system pressure (working pressure) at which the hose can be operated continually.
* The test pressure at which a hose is guarantee to withstand pressure peaks.
*  The burst pressure at which the house wall rupture.
The S.A. E. recommended working pressure for hydraulic hose is 25 per cent (or one quarter) of the mini-mum specified burst pressure. This safety margin allows for the absorption of pressure surges. For internal diameter calculations, use the nomogram (fig.) or the formula given for pipe sizing.

Construction

High pressure hose is a length of tubing made flexible by means of convolutions. It may be readily bent and yet remain gas and liquid tight.  High pressure hose is made of Core tube nylon over braid Fiber Reinforcement . The components can be weld to the end of the house. End connections include tube fitting, tube adapter, VCO, VCR and NPT.
