Hyparflex Close Pitch Metallic Hose

The Hyparflex Close Pitch Metallic Hose is a annular corrugated metallic hose in the Stainless SS Corrugated family. Type 316L SS core with triple braid of Type 304 SS. Working pressure to 175 bar, operating temperature -200°C to +650°C.

Construction

• Type: Stainless SS Corrugated — Close-pitch annular for tight bend radius
• Construction: Annular Corrugated
• Core material: Type 316L SS
• Braid: Triple Braid — Type 304 SS
• End fitting material: Carbon steel ASTM A105, 304SS or 316SS — flange / NPT / sanitary / camlock per order
• Nominal ID range: DN 6 (1/4") to DN 150 (6")
• Bend radius (static): 9 mm minimum
• Bend radius (dynamic): 110 mm minimum

Performance

Maximum working pressure 175 bar at the smallest bore (decreases with increasing diameter — refer to the OEM size table for per-size ratings). Minimum burst pressure 700 bar with safety factor 4:1 per ISO 10380. Operating temperature range -200°C to +650°C (continuous service; intermittent excursions evaluated on request). All assemblies hydrotested at 1.5× working pressure with a witness-test certificate available on request.

Applications

• Tight-bend installations / instrument tap-offs
• Confined-space high-vibration connectors
• Flexible joints in compact equipment skids
• Robotic / articulated motion lines

Compliance

• ISO 10380:2012 PSL 1 (Corrugated Metal Hoses and Hose Assemblies)
• Pressure Equipment Directive 2014/68/EU Module H
• EN 10204 3.1 / 3.2 mill test reports on request

How to order

Confirm (a) line working pressure and process medium, (b) operating temperature range, (c) bore size and overall length, (d) end fitting type per side (NPT / BSPP / ANSI 150-1500# RF / DIN PN10-PN40 / sanitary tri-clamp / camlock / butt-weld / etc.), (e) braid configuration (unbraided / single / double / triple — drives pressure rating), (f) any required certifications (ISO 10380 PSL class, PED Module, ASME conformance, NACE MR0175, CGA / UL / Chlorine Institute). Indus quotes ex-Dubai for stock items and ex-OEM for build-to-order, with mill test reports and pressure-test certificates included.

Companion products

Pair with matched ANSI flange gaskets, hose clamps, and OEM end-fitting hardware. For high-vibration installations, also specify a Lock-Section or Armor-Flex external hose guard. For fire-rated runs, add a Fry-Sil Fire Jacket or Fire Tape covering. For high-cycle or premium-corrosion service, ask about the matched OEM expansion-joint variant of the same alloy and pressure class.
