helically corrugated hoses

Product catalog summary

Materials and Construction:
The BOA DUO helically corrugated stainless steel hose is constructed from stainless steel 1.4571 (similar to AISI 316 Ti) for the corrugated hose and stainless steel 1.4301 (similar to AISI 304) for the braid. Special materials are available upon request.

Specifications:
The document provides detailed specifications for various diameters (DN) of hoses, including permissible working pressure at 20°C, inside and outside diameters, tolerance, bend radius (static and dynamic), weight, production length, and item numbers. The hoses are available in different braid types (A, B, C) with varying pressure ratings and dimensions.

Design and Features:
The metal hoses are double-ply, helically corrugated, and resistance welded at the crest, offering high flexibility and excellent vibration absorption. The design complies with the ISO-10380 standard, ensuring stability and performance in high-pressure applications.

Applications:
The hoses are suitable for high-pressure applications, vibration absorption, engine construction, pumps, compressors, and heavy-duty pressure pipes under extreme conditions.

Additional Information:
The document references additional technical instructions for metal hoses and assemblies, including reduction factors for heavy-duty conditions. It also mentions the integration of technical information, installation instructions, and guarantee/delivery terms as part of the product information.
