Product catalog summary
Overview: The document provides technical specifications for PARRAP®, a high-performance flexible stainless steel corrugated hose designed for extreme environments ranging from -273°C to 600°C. It is resistant to natural aging and manufactured using hydroforming technology to ensure high flexibility and accuracy. The design and testing comply with EN ISO 10380 standards.
Materials: The corrugated hose is made from stainless steel 1.4404 (similar to AISI 316 L) or 1.4541 (similar to AISI 321), except for DN6, 8, 10, 125. The braid is made from stainless steel 1.4301 (similar to AISI 304).
Specifications: The hose is available without braids (0), with one braid (A), or two highly compact braids (B). The document lists detailed specifications for various diameters (DN) including inside and outside diameters, bend radius, maximum allowable pressure, and burst pressure at 20°C. The specifications also include item numbers for different material types.
Performance: The hose offers very good lifetime resistance, with 50,000 cycles, which is five times superior to the EN ISO 10380 standard. It also features a reduced bending radius, improved by 25% over the standard.
Applications: PARRAP® is suitable for fluid transfer applications involving liquids or gases, vacuum technology, cryogenics, the petrochemical industry, the nuclear industry, instrumentation, and air conditioning.
Ordering Information: To place an inquiry or order, the following information is required: item description (PARRAP®), BOA item number, material, DN, braid type, and quantity.
Additional Information: The document references three leaflets that are part of the product data sheet: "Technical Information", "Installation Instructions", and "Guarantee/Delivery terms/Conditions". Specifications are subject to change without notice.
