Tube fitting enables safe and repeatable meeting and reliable leak-free operations

ower management firm Eaton – now a part of Danfoss Power Solutions (Sealing Technology, September 2021, web page 2) – recently expanded its product portfolio with the addition of the robust WALRINGplus delicate seal slicing ring system, optimised for thin-wall tubing.
Featuring a two-edge cutting ring, with extra gentle sealing for each possible leak paths, this tube fitting system allows simple, protected and repeatable assembly and reliable, leak-free operations.
It is designed to meet demanding requirements, involving hydraulic tube fitting in purposes including use in agriculture, development, commercial autos, discrete manufacturing, rail transportation and different industries.
It is appropriate for use with thin-walled tubes and, subsequently, helps efficient weight and gasoline reduction of mobile machinery and shifting components of stationary equipment.
Correct meeting is crucial to tube becoming efficiency and WALRINGplus is designed to stop excessive or inadequate tightening. A clear block-stop operate provides a tangible torque increase when the top of an meeting is reached, so no torque or distance measurement is required.
In addition, a considerably decrease pressure is needed to drag the slicing ring over the tube – making meeting simpler, sooner and safer, while lowering the risk of injury to the delicate seal. The O-ring groove position additionally enables frequent reassembly, with out affecting efficiency.
To eliminate the chance of leaks that may create pricey harm 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 force is reduced. Problems caused by low assembly torque also may be recognized before the chopping ring is pulled from the tube – reducing the danger of a catastrophic failure in application.
The bespoke M-R7 machine additional reduces assembly time and the effort required for WALRINGplus in addition to the risk of leaks. By automating the method of cutting-ring meeting and tube-forming, this machine helps guarantee optimum system efficiency while additionally reducing the required torque and rotrotation.
เกจวัดแรงดูด of WALRINGplus: • steel chopping ring with Viton O-rings; • for tube sizes 6–42 mm; • complies with ISO 8434-1; • excessive burst-pressure exceeding four:1 security factor; • working strain as much as 500 bar (L-series) and 800 bar (S-series); and • supports dry assembly with metal elements.
