Walpro
Profile ring tube fittings.
The WALPRO profile ring fitting has been optimized in its entirety to satisfy the market requirements of today and tomorrow.
Greatly improved performance values and more reliable assembly have been achieved with the aid of modern computing methods. The improvements are due primarily to an axially stiff ring design which has been specifically weakened radially by profiling the shoulder. The new chip geometry results in a high degree of tightness and eliminates subsequent penetration-
The main benefits for the user are:
greater functional reliability
lower assembly costs
lower reworking costs
lower operating costs
The Walterscheid profile ring permits the application of a novel assembly method: controlled final assembly.
Main characteristics.
optimized cutting area
optimized cutting edge angle
wedge-shaped cutting flank
chip upsetting groove
stable cutting area
optimized center area
Ideal contact angle
Cone stop limit for assembly preventing excessive tightning
optimized shoulder area
profile shape with strengthening effect
large contact surface ring-nut
end radius
no bulging
thus positive load distribution on the ring
radial flexibility
thus positive clamping of the tube
axial strengthening
(strengthening ribs)
thus high degree of tube connection
high degree of tightness
High degree of sealing efficiency
100% connection between the cutting ring and the tube
High sealing strength (pre stress)
No settling or subsequent penetration
Cross section - Profile ring
Profile system = strengthened ring, no settling
Chip upsetting = no subsequent penetration
Negative clearance angle = additional sealing zone,essentially higher sealing pressure
Cross section-Two-edge cutting ring
Thin cross section of ring = settling of connection
Partially uncovered cutting section = subsequent penetration, settling
Zero clearance at cutting edge = sealing for tube only on face, bad sealing to body
Safe tube connection
Large ring contact area
High-strength profile-shaped ring
High tensile strength
High nominal pressures
L-series for nominal pressures up to 500 bar
S-series for nominal pressures up to 800 bar
High nominal pressures only obtained by original Walterscheid components
Safe assembly
Safe assembly due to limit stop
Safe reassembly
High fatigue strength
Intelligent tube connection
Notch-free tube clamping
Universal standard solution
All fitting components are to DIN 2353 and ISO 8434/T1
Suitable for all common tube materials
Interchangeable with cutting ring and two-edge cutting ring

Walform
The innovative solution
WALFORM plus is a positive tube fitting system that consists of just three components.
The mechanically reshaped tube end is positively connected by a conventional DIN fitting body and a DIN nut, the only possible leakage path being sealed off by an elastomer ring.
One characteristic feature of the new series is the shoulder on the end face of the reshaped tube, which is inserted into the 24° cone of the body. This results in a marked improvement in assembly bahaviour and good protection against excessive tightening.
A gain in economy:
Few parts (reduced material and logistics costs)
Inexpensive
Simplest assembly
No preliminary or follow-up work required
A gain in safety due to positive connection:
Secure / Pressure-resistant
Absolutely leak-proof
Tolerates assembly errors
A gain in easy of assembly:
Few separating / sealing points
Reliable assembly / Clear end of assembly
Short assembly times, low torque
Far lower tightening torque compared to all cutting-ring tube fitting systems
Electronically controlled reshaping machines guarantee efficient production at high and constant quality - both stationary and locally.

MEG-WF-2
For reshaping steel tubes with outside diameters form 6 to 42 mm and stainless steel tubes with outside diameters from 6 to 30 x 3 mm. By changing tools, the MEG-WF2/BO machine can also be used as a flaring machine for Walterscheid-37° SAE flared flanges up to 60.3 mm.
|
 |
MEG-WF-3
For reshaping steel tubes and stainless steel tubes with outside diameters from 6 to 42 mm. By changing tools, this machine can also be used as a flaring machine for Walterscheid-37° SAE flaring flanges for all diameters to 101.6 mm. |
Flare Tube Fitting
The Walterscheid flare tube fitting has been optimized in its total and satisfies the market requirements of today and tomorrow.
High performance and safety of assembly have been achieved with the aid of latest computing methods, and are due primarily to an optimized component geometry.
A high degree of tightness is obtained through the use of two elastomeric seals. Anti-friction coated threads and a retaining collar at the centre unit ensure safe handling.
The main benefits for the user are:
Higher safety of assembly in comparison to cutting rings
Low tightening torque
Lower reworking costs
Lower operating costs
High degree of fine sealing efficiency
Elastomeric sealing between body and tube
No settling of the connection
Reshaping machines
MEG-WF1/BO-2
For flaring tubes with a tube OD of 16 to 42 mm. By simply changing the tool, this machine can also be used as a WALFORM machine for all tube Ods from 6 to 20 mm. (Material St 37.4)

Flaring Flanges
Connecting without welding
"SAE 37°" is a new range of flared flange products offering a low-cost alternative to tube fittings which previously required welding.
No tack-welding, no full welding, no pickling, and a radical reduction in the investment outlay for the necessary manufacturning facilities!
Walterscheid offers electronically controlled reshaping machines for flaring. That ensures efficient production and consistently high quality - both in the factory and in the field.
Main characteristis
Optimum sealing effect due to two elastomer seals in the centre unit and positive connection
Easy assembly due to a centring aid on the centre unit
Maximum reliability of assembly due to 37° flare technology
Metric screw thread

MEG-WF2/BO
For flaring tubes with a tube OD of 16 to 60 mm. By simply changing the tool, this machine can also be used as a WALFORM machine for steel tube with Ods from 6 to 42 mm and stainless steel tubes with Ods from 6 to 30 mm (Material St 37.4 and St 52.4) |
 |
MEG-WF3/BO
For flaring tubes with a tube OD of 16 to 106,1 mm. By simply changing the tool, this machine can also be used as a WALFORM machine for steel tubes and stainless steel tubes Ods from 6 to 42 mm. |
Usable tube dimensions
The standard range includes tube dimensions from 16 x 2 to 60 x 8 mm. A tube grade suitable for cold-bending and flareing is to be used.
We recommend the use of seamless precision steel tubing with dimensions to DIN 2391, Part 1 C, material St 37.4 and St 52.4 to DIN 1630,Type NBK-3.1 B.
