What protection does this core provide?

Mechanical protection — physical impact, vibration, abrasion. Lock-Section provides interlocking ring protection that does not separate under axial load.

What sizes are available?

DN 25 (1") to DN 200 (8"). Designed to fit over the standard hose bore range — confirm host hose OD on the RFQ.

What materials are used in construction?

Core / wrap: Type 304 SS. End fittings: 316L SS standard.

Why this specialty design?

Lock-Section uses interlocking metal rings rather than continuous helical corrugation. Each ring locks against its neighbor, preventing separation under axial load. Used where the hose must resist pull-through during pressure or impact events.

Is this suitable for sour-service (H₂S) wells?

No — this is standard service. For sour-service, specify the NACE-compliant variant on the RFQ.

What standards and certifications are supplied?

ASME B31.3 (where pressure-rated). EN 10204 3.1 / 3.2 mill test reports.

What is the lead time?

Typical lead time 35 working days ex-works OEM. Common configurations are short-lead from OEM stock or scheduled production.

Product description

The Thorburn LS Series — Lock Section, 304 Stainless Steel is a specialty metallic core product. Interlocking Lock-Section core (304 SS) — specialty metallic core for service requiring mechanical protection (vibration, abrasion) beyond standard corrugated hose capability.

Construction

Type: Specialty Metallic Core — Interlocking Lock-Section core (304 SS)
Construction: Annular Corrugated
Core / wrap material: Type 304 SS
End fitting material: 316L SS standard
Nominal ID range: DN 25 (1") to DN 200 (8")
Bend radius (static / dynamic): 100 / 0 mm minimum
Weight: ~1.5 kg/m

Performance

Mechanical protection rating: physical impact, abrasion, vibration absorption beyond standard corrugated hose capability. Operating temperature -200°C to +540°C continuous. Each assembly inspected at OEM facility against the applicable specification.

Applications

Bulk-material handling (vacuum / suction)
Vibration-absorbing connectors with pull-through risk
Industrial dust collection lines
High-impact mechanical service

Compliance

ASME B31.3 (where pressure-rated)
EN 10204 3.1 / 3.2 mill test reports on request

How to order

Confirm (a) line working pressure (or for fire-protection: the host hose specification), (b) operating temperature range, (c) bore size and overall length, (d) end fitting style, (e) braid count where applicable, (f) any required certifications. Indus quotes ex-OEM with mill test reports and pressure-test certificates.

Companion products

Apply over standard metallic hoses to upgrade impact / vibration / abrasion protection. Lock-Section provides interlocking mechanical protection; Armor-Flex adds ball-joint articulation; Smooth-Flex provides a non-corrugated alternative. Indus also supplies matched ANSI flanges, gaskets, and stud bolts.
