The document outlines the specifications for pressure vessels and generators made from high-strength stainless steel, with volumes ranging from 0.25 to 30 liters and a maximum length of 2,000 mm. The connection system uses a 60° Cone & Thread HP-Fitting, conforming to the Pressure Equipment Directive, Article 4, paragraph 3. Variants for different media, pressure, and temperature ranges are available upon request.
WEH® offers pressure generators with pneumatic or hydraulic drives, suitable for applications requiring high pressures. These include spindle pumps, pneumatic pressure intensifiers, and hydraulic pressure intensifiers. Autoclaves with integrated spindle pumps are also available for thermal treatment and chemical process investigations.
WEH® provides custom high-pressure systems for various applications such as carfrettage plants, hydroforming plants, isostatic presses, high-pressure test benches, and ultra-high-pressure homogenizers. The company offers consultation for implementing high-pressure systems for other applications.
A range of tools for tube processing is available, including cutting blades, countersinks, clamping jaws, thread-cutting dies, and more. Specific tools like thread cutters, cone cutters, cone reworkers, and tube benders are designed for manual operations on high-pressure lines.
The appendix provides definitions and explanations of terms related to pressure specifications, dimensions, ports, and other technical data. It includes details on pressure equipment directive compliance, intended use, product selection, and storage/lifetime of components. The document emphasizes the importance of using WEH® products within specified limits and consulting WEH for special applications.
The document highlights the importance of using the latest versions of catalogs and product documents. It advises consulting WEH for binding information and recommendations, especially under unusual operating conditions. The document also notes that illustrations and technical details are for illustrative purposes and may not reflect the actual product.

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...
