Tube becoming permits secure and repeatable assembly and reliable leak-free operations

ower management company Eaton – now part of Danfoss Power Solutions (Sealing Technology, September 2021, web page 2) – lately expanded its product portfolio with the addition of the sturdy WALRINGplus gentle seal cutting ring system, optimised for thin-wall tubing.
Featuring a two-edge cutting ring, with further delicate sealing for both potential leak paths, this tube becoming system permits simple, protected and repeatable assembly and dependable, leak-free operations.
It is designed to meet demanding necessities, involving hydraulic tube fitting in applications together with use in agriculture, construction, business automobiles, discrete manufacturing, rail transportation and other industries.
It is appropriate for use with thin-walled tubes and, subsequently, supports efficient weight and fuel reduction of cell equipment and transferring parts of stationary machinery.
Correct assembly is essential to tube fitting efficiency and WALRINGplus is designed to forestall excessive or insufficient tightening. A clear block-stop operate offers a tangible torque increase when the end of an assembly is reached, so no torque or distance measurement is required.
In addition, a significantly lower pressure is needed to pull the cutting ring over the tube – making assembly easier, quicker and safer, whilst decreasing the danger of damage to the delicate seal. diaphragm seal -ring groove place also allows frequent reassembly, without affecting efficiency.
To remove the risk of leaks that may create pricey damage and downtime, WALRINGplus also addresses their frequent root causes.
Soft sealing prevents leakages if: tubes or studs are slightly scratched, the fluid temperature fluctuates or the retention drive is reduced. Problems brought on by low meeting torque also can be recognized before the chopping ring is pulled from the tube – decreasing the danger of a catastrophic failure in application.
The bespoke M-R7 machine further reduces assembly time and the trouble required for WALRINGplus in addition to the chance of leaks. By automating the method of cutting-ring meeting and tube-forming, this machine helps guarantee optimum system performance whilst also reducing the required torque and rotrotation.
Specifications of WALRINGplus: • metal cutting ring with Viton O-rings; • for tube sizes 6–42 mm; • complies with ISO 8434-1; • excessive burst-pressure exceeding four:1 safety issue; • working stress as a lot as 500 bar (L-series) and 800 bar (S-series); and • supports dry assembly with steel components.
