BOA ISO - K

Product catalog summary

Overview
BOA AG offers flexible vacuum connectors designed for high-quality performance in the vacuum industry, suitable for applications ranging from gross to ultra-high vacuum levels. These connectors are equipped with ISO-K clamped flanges and are designed to minimize load transfer to end connectors while maintaining stability under pressure.

Construction Characteristics
The connectors are constructed using BOA's proven methods, featuring single-ply bellows and hoses made entirely of high-grade chrome-nickel steel. The flanges are welded on both sides according to DIN 28404 standards.

Material
The bellows or hose units are made from stainless steel DIN 1.4571 (AISI 316 Ti), which is titanium stabilized and contains molybdenum for enhanced corrosion resistance against pitting, stress cracking, and intercrystalline attack, withstanding temperatures up to 550°C.

Temperature Resistance
The connectors can operate in temperatures ranging from -200°C to +550°C. For applications requiring higher temperatures, consultation is advised.

Leak-tightness
Each unit is mass spectrometer tested with helium, ensuring a leakage rate of less than 1x10^-9 mbar l/s.

Delivery Status
Flange sealing areas are protected by plastic caps and the units are sealed dust-free in plastic bags.

Quality Management
BOA AG adheres to the latest professional standards in design, dimensioning, manufacturing, and testing. The company is certified according to EN ISO 9001:2008 and 14001:2004, with regular controls and tests by accredited authorities.

Product Specifications
The document provides detailed specifications for various models of flexible vacuum connections, including dimensions, movement capabilities, and item numbers. The connectors are available in different nominal sizes (DN) and lengths, with additional lengths available upon request.

Ordering Information
When placing an order, customers should specify the nominal size (DN), length (L), BOA item number, and quantity required.

Flexible vacuum connections BOA ISO-K with clamped flanges acc. to DIN 28404 Description These flexible connectors specially designed by BOA AG comply with the highest quality requirements of the Vacuum Industry from gross to ultra-high vacuum levels. Their special design ensures that only smallest loads are transferred to the end connectors, maintaining nevertheless stability when put under pressure. Fitted with ISO-K clamped flanges, these flexible connectors provide a fast and economic solution. The flexible element of shorter connectors consists of BOA instrument bellows, longer units use annularly (parallel) corrugated BOA metal hoses. Both executions are designed to compensate for axial, lateral and angular movement and to absorb vibration. BOA AG provides short-term delivery for a complete standard range from DN 63 to DN 250. Construction characteristics Bellows and hose construction according to proven BOA methods and procedures, single-ply, completely made of high level chrome-nickel steel, with clamped flanges ISO-K according to DIN 28404 welded on both sides. Material The bellows or hose unity is made of stainless steel DIN 1.4571 (AISI 316 Ti). This 18-8 austenitic type stainless steel is titanium stabilized and has molybdenum content giving it better corrosion resistance to pitting, stress crack and intercrystalline attack up to a working temperature of 550°C. Temperature resistance From -200°C up to +550°C. For higher temperatures please ask. Leak-tightness Mass spectrometer tested with helium. Leakage <1x10-9 mbar  l/s. Delivery status Sealing areas on flanges protected by plastic caps. Dust-free sealed in plastic bag. Quality management Design, dimensioning, manufacturing and final tests of BOA products follow latest professional and state-of-the-art procedures. Regular controls and tests executed by accredited authorities for enterprise and product certification confirm the efficient and professional continuity of BOA process management. BOA AG is certified according to EN ISO 9001:2008 and 14001:2004. Continues on the next page
