Systèmes utilitaires Cleanroom
Pipeline d'air comprimé propre
A corrosion-resistant 40 mm modular aluminum header with a crown-fed 25 mm gooseneck drop, full-bore push-fit joints, supported outlet valve and dedicated low-point condensate drain.
- 40 mm header with 25 mm service drop
- Full-bore push-to-connect joints
- Crown take-off and low-point drainage
Introduction de produit
Clean Compressed Air Piping distributes already-treated air between the compressor-room treatment train and cleanroom equipment without the rust scale and rough internal surfaces associated with conventional ferrous pipe. The selected catalogue-scale assembly uses two smooth 40 mm blue aluminum header sections and one 25 mm gooseneck branch assembled with reusable push-to-connect fittings. Its reducing tee faces upward from the header crown, then two elbows carry the branch over and down to a single red-handled point-of-use valve. The header is supported on snap-shut clips and pitched slightly toward one dedicated low-point drain, limiting bottom-fed dead legs and making moisture removal accessible. The piping does not filter, dry, sterilize or regulate air on its own; delivered air quality remains a property of the complete treatment, installation and maintenance system.
Key Features
A 40 mm main header supplies a 25 mm service drop while preserving a visibly clear distinction between distribution and point-of-use pipe sizes
Full-bore push-to-connect fittings avoid threaded or welded joints along the modular aluminum run and support later reconfiguration
The crown-facing reducing tee and raised gooseneck branch discourage settled condensate from flowing directly into the service drop
A dedicated drain valve at the pitched header's low end provides one accessible condensate-removal location without creating multiple hidden pockets
The red-handled ball valve isolates the single equipment outlet without turning the piping kit into a regulator or filter assembly
Six snap-shut clips on three metal support rails restrain the header and drop while leaving joints visible for inspection
Distinct blue tube, black fittings, red isolation handle and natural-metal supports provide conventional compressed-air identification and clear maintenance recognition
Préoccupations du client produit
Reliable clean-air delivery depends on network sizing, drainage geometry, support spacing, joint preparation and the upstream treatment train rather than pipe diameter or color alone.
An undersized header or excessive number of fittings can leave equipment below its required inlet pressure during simultaneous demandSize the header from peak coincident flow, total equivalent length and minimum supply pressure, then check the complete route against a loaded-system pressure-drop objective of approximately 0.07-0.14 bar (1-2 psi) or less.
A branch taken from the bottom of the main can carry condensate directly to valves, instruments or production equipmentUse the upward crown-facing tee and raised gooseneck before the vertical drop, pitch the header toward the separate low-point drain and keep that drain accessible.
Poorly prepared tube ends or damaged seals can create small leaks that waste energy and destabilize branch pressureCut square, deburr and clean each tube, mark the insertion depth, inspect the gripping and NBR sealing rings, and complete leak testing before service.
Unsupported pipe movement can load fittings and cause alignment or sealing problems during pressure and temperature cyclesUse the specified snap-shut clips on independent support rails, maintain manufacturer spacing and allow controlled expansion without hanging unrelated equipment from the pipe.
A clean distribution pipe may be mistaken for a device that creates sterile, oil-free or ultra-dry airDefine the required purity at each outlet and provide the appropriate upstream compressor, dryer, coalescing, adsorption and final filtration stages separately from this distribution kit.

Paramètres techniques
The selected purchasable display identity is a 40 mm OD modular aluminum main with a 25 mm crown-fed service drop. It fixes two 40 mm header tubes, three 25 mm branch tubes, one 40 x 25 mm reducing tee, two 25 mm elbows, one 25 mm straight union, one threaded outlet block, one red-lever service valve, two different header end caps, one compact low-point drain valve, six snap-shut clips and three galvanized support rails. Comparable manufacturer systems use smooth extruded aluminum tube, full-bore push-fit joints, engineered-polymer fittings and NBR seals, with temperature-dependent maximum system ratings commonly reaching about 13-16 bar. This page limits the selected normal operating envelope to 10 bar; actual allowable pressure, flow and support spacing follow the final component family, temperature, route and local design requirements.
