1.1 | General Overview High pressure solutions from WEH® High pressure components from WEH® stand for uncompromising qua lity and tangible benefits: ► Two systems for a wide range of pressure ranges: ► WEH® components are compatible with all commercially available 60° cone and thread pipe fittings. ► All WEH® ultra-high pressure components are available with both metric and imperial thread connections. ► Medium pressure components made of 1.4404, high pressure components made of 1.4542 / 17-4 PH (around 50% higher strength than 1.4404). ► Specially hardened materials on the valve seats. ► Thanks...

Applications and industries WEH® high pressure solutions are in demand wherever media need to be stored and moved under high pressure. With our solutions, we serve numerous customers from various industries such as the manufacturing industry, mechanical engineering, companies with testing facilities and research institutes. Typical applications of such high-pressure systems are: • Test benches for pressure and leak testing • Hydrogen applications in mobility and industry • Isostatic presses • High-pressure treatment of food • Plants in petrochemicals and mining Pressure tests Water jet technology...

1.3 | Technical Product Overview WEH® high pressure solutions are available in two different pipe connection systems for different operating pressures: ► 60° cone and thread medium pressure fitting up to 1,379 bar / 20,000 psi ► 60° cone and thread high pressure connection from 2,500 bar / 35,000 psi to 10,000 bar / 150,000 psi Pipelines are available in standard sizes of 1/4“, 3/8", 9/16“, 3/4", and 1“ (external diameter). The following nominal diameters are available as standard for each pressure rating: For tube processing by customers, WEH® offers an extensive range of tools. We are also...

ASSEMBLY OF HIGH PRESSURE TUBES High pressure connections are composed of an outer cone which acts as a sealing surface, as well as a left-hand thread for attachment of the Collar. Inside the screw connection, an inner cone with a 2-5° larger angle is installed as a counterpart along with a female thread for the Gland. When assembling high pressure tubes, the Gland must first be pushed onto the tube and then the Collar (note: left-hand thread) must be screwed onto the tube until roughly 2 threads remain open from the cone (Figure 2). As a result, the used thread length of the Gland is maximized...

2 | High pressure Components up to 1,379 bar / 20,000 psi • Special sealing contour for leak-free connection • Optimized flow rate, as nominal width of fittings is higher than that of tubes • Easy conversion/replacement thanks to identical size of cross, T and angle piece • Diagonally arranged fixing holes protect the screw connections from twisting WEH® fittings ensure the leak-free connection of pipe components. The cone and thread fittings are a simple and reliable fitting system. All fittings are supplied complete with the appropriate fittings. WEH® medium pressure fittings are metal-to-metal...
