SPECIAL HOSES Trelleborg hoses are produced from the best hose building materials, incorpo-

rating wear, oil and heat resistant rubber compounds, such as NR, SBR, NBR,

EPDM, Silicone, and Viton, which are chosen to precisely match the intended

use of the hose . The pressure bearers consist of: cord materials made from

rayon, polyester or aramide fibres, and components in the form of flanges,

rings etc.

Production is directed from the project office and takes place on advanced

production lines with automatic winding machines and computer controlled

autoclaves for the vulcanization process. The entire process is monitored by our

own integrated quality system, in which the standards used are much higher

than normal.

Water hose

Suitable for drinking water and many other water facilities.

FLEXIBLE JOINTS Quick and efficient supply of custom-made, non-standard products, such as

expansion joints in non-standard lengths and with non-standard flanges.

Preformed rubber bends for suction or discharge applications with extra wear-

resistant inner layers. Adapters made from wear-resistant elastomers with thick

walls in almost every required shape (circle, ellipse, rectangle). Adapters with

every diameter and length. Pinch valves with mechanical, hydraulic and/or

air pressure flow control. Y-pieces for making wear-resistant tie-ins easy for all

kinds of industrial application. Also hoses for drainage systems with vulcanized

rings and/or spiral, which can stand vacuum and the pressure of soil.

Reducers

A reduction in the diameter of the pipe often causes

turbulence in the flow and results in increased wear

and tear. We produce wear-resistant reducers for this

application in every required diameter and length.

Adapter

As well as reducers, we have various adapters in our

range. These are flexible connections with, for example,

a circular flange on one end and a rectangular flange

on the other. We can produce any other shape you may

require upon request. These adapters are made with

extra thick walls using wear-resistant elastomers so that

they have a long life.

Pinch valve

Pinch valves consist of a

flexible hose built into a steel or

aluminium casting. By throttling the

hose the flow can be controlled. We supply the

flexible hoses which are used in these pinch valves.

Flexible telescopic hose

Flexible telescopic transport hoses

for abrasive media. Used for crossing

over a gap between different loading

/unloading heights. Can be supplied

in various diameters and types.

Y-piece

Y-pieces are very sensitive to wear

and tear. Building them completely

from elastomers results in a flexible and

wear-resistant construction.

Pre-formed bend

In many material transport

systems the bends are sensitive

to wear and tear. We supply an

extensive range of pre-formed

bends for both suction and

discharge purposes, in various

diameters and radii.

Drainage hose

Drainage hoses are used where a flexible

connection is essential. The drainage hoses are available in very

large diameters and are fitted with integrated vulcanized rings and/or

spirals to stand the pressure of the soil when buried and to stand

vacuum conditions.

Riser pipe

Rubber risers for

vacuum cars to give

a longer lifetime,

compared with the

steel risers which

are normally used.

Available in various

sizes, shapes and

qualities.

FLANGES A reliable and safe transport hose is a balanced product, where all the components

must fit together perfectly. The end piece is formed by the flanges, and we supply

technically superior solutions for this application, which are suitable for a wide

range of working pressures and all loads. Examples are : The rubber flange ( no

gasket required ) with a steel or stainless steel backing ring for medium working

pressures. The Double Action flange; a form-fit flange construction for higher

working pressures, and suitable for very high axial loads. Vulcanized flange

couplings for every working pressure, with optional swivel flanges, in accordance

with the DIN and ANSI norms, for easy fitting.

Double Action flange

The Double Action flange is our

most recent development. The main

feature of this flange is the superior

axial strength due to an integrated

locking flange. A flange is able to

accept high bending loads due to a

thick integrated flange and backing

flange and will not fall apart due

to rust. The thick integrated flange

and backing flange allow for a large

radius in the flange neck, with no

cutting forces on the cords.

Steel coupling vulcanized in

Our solid steel couplings are suitable for heavy

duty applications. They can be made with the

smallest possible pitch circle diameters and are

vulcanized into the hose. These couplings are

also secured with our safety strap system for extra

safety. We use these couplings as standard in our self

floating hoses so that you can work during bad weather

without the risk of a defective line.

Swivel flange

The swivel flange is

used with medium

service pressures at

points where the bolt

holes in the mounting

flanges are not precisely

aligned. The swivel flange

simplifies fitting between 2

fixed points.

R

Rubber flange-steel backing flange

This flange is used for

medium pressures

and suction hoses.

The rubber flange

means that the

hose can remain

relatively short,

starting from a

maximum angle of

curvature. Because the

wear resistant rubber layer

extends partly into the top edge of the

flange, it forms a good seal with the flange

connection itself.

R

R

Widened collar

There are many

options for connecting hoses

with straight ends. However, a big

disadvantage of these hoses is that when

a pipe is inserted it can form an obstruction in

the hose. This can be prevented by using a hose with

a widened collar. Because the ends are wider, the pipe which is

not inserted does not cause any obstructions in the hose,

resulting in an optimum flow. Collars can only be used for low

pressure applications.

Hose coupling

Hose with fixed or swivel flanges in

accordance with DIN or ANSI with

press sockets (aluminium, steel or

stainless steel).

design process and advanced production methods. Everything about it has

been thought out in more detail, so that even its standard quality is superior to

comparable products. We supply products exactly according to your specifications

for material composition, pressure and temperature requirements, level of

resistance, dimensions, flange choice, safety, vibration and sound reduction,

and whatever else you require. In order to guarantee that you receive the very

best product, each delivery is subjected to a stringent final inspection by Trelleborg,

which can be supplemented by whichever approval certificate you desire…
