Equipment and spare partsBrowse manufacturers Search by manufacturerDirect factory deliveries of authentic AZ Intec GmbH (Olbernhau, Germany) components: WS stainless steel corrugated metal hoses, TAS thermal shut-off gas ball valves, ultra-high-pressure fittings up to 500 bar, cleanroom medical gas modules, and pre-insulated solar conduits.
Industrial corrugated metal hoses and flexible bellows assemblies from AZ INTEC (WS110, WS120, and WS-Flex series) are precision-manufactured from high-grade austenitic stainless steel grades 1.4404 (AISI 316L) and 1.4571 (AISI 316Ti). Designed for thermal expansion compensation, structural vibration damping, and conveying hazardous gases, steam, and cryogenic fluids under temperatures from -200 °C to +550 °C and operating pressures up to 250 bar. Hydroformed parallel corrugations ensure high cycle life and pressure integrity.
AZ INTEC gas safety shut-off valves integrate high-precision Thermal Armature Safety (TAS) mechanisms directly into full-bore ball valve assemblies. Upon exposure to ambient fire temperatures exceeding +100 °C, the fusible thermal trigger instantly releases a spring-loaded mechanical shut-off, hermetically isolating gas flow within 60 seconds. Fully certified under DIN EN 331 and DVGW VP 305-1, withstanding extreme fire exposure up to +650 °C for 30 minutes (thermal resistance class GT5).
AZ INTEC ultra-high-pressure fittings, manifolds, and cylinder connectors are engineered for technical gas filling stations, compressor manifolds, gas booster systems, and test rigs operating from 100 to 500 bar (10–50 MPa). Precision CNC-machined from corrosion-resistant stainless steel 1.4571 (316Ti) or high-density brass CW614N, fully compliant with DIN 477 and ISO 10297 standards with helium leak rate verification.
AZ INTEC Solar pre-insulated flexible piping systems offer dual-line (Duo-Solar) or single-line corrugated stainless steel conduits (grade 1.4404 / 316L) for solar thermal collector fields and storage tanks. Encased in high-density closed-cell EPDM elastomer insulation with UV-resistant outer protection, rated for continuous fluid temperatures up to +150 °C and collector stagnation surges up to +175 °C (intermittently +220 °C).
AZ INTEC medical gas components are manufactured in cleanrooms (ISO Class 7/8) in strict conformity with DIN EN ISO 15001 standards. The portfolio supplies centralized distribution manifolds, isolation valves, terminal units, and high-pressure flexible pigtails for medical oxygen (O2), nitrous oxide (N2O), medical air, carbon dioxide, and hospital vacuum systems across surgical suites.
AZ INTEC Pump-Flex flexible stainless steel bellows hoses are tailored for connecting outdoor and indoor modules of air-to-water and geothermal heat pumps, rooftop chillers, and HVAC units. The high-flexibility 1.4404 corrugated bellows geometry dampens up to 85% of compressor vibrations and acoustic pulsations, preventing wall structural transmission while protecting brazed plate heat exchangers.
Aligned with clean energy transition, AZ INTEC delivers certified H2-Ready valves, high-pressure fittings, and metal hose assemblies engineered specifically for molecular hydrogen (H2) and hydrogen-methane blends. Utilizing high-nickel austenitic stainless steels (>12% Ni) and orbital micro-plasma welding, mitigating hydrogen embrittlement and guaranteeing ultra-low helium leak rates below 1x10^-8 mbar·l/s.
AZ INTEC corrugated stainless steel coiled heat exchangers and tank valve assemblies are designed for integration within thermal buffer vessels, domestic hot water indirect cylinders, solar storage tanks, and chemical reactors. Helical corrugated contours generate continuous internal micro-turbulence, boosting heat transfer coefficients by 35–45% compared to plain smooth tubing while resisting scaling.
German manufacturer AZ Intec GmbH possesses over four decades of specialized engineering expertise in producing high-integrity components for demanding fluid systems.
Fabricated from premium austenitic stainless steels 1.4404 (AISI 316L) and 1.4571 (AISI 316Ti), all products exhibit superior resistance to intergranular corrosion, pitting, and stress corrosion cracking in aggressive operating environments.
For ultra-high-pressure manifolds up to 500 bar, dense forged brass alloys CW614N and precision CNC stainless components undergo comprehensive ultrasonic testing and stress-relief heat treatment.
AZ INTEC specialized gas ball valves integrate patented Thermal Armature Safety (TAS) technology directly inside the valve body.
Upon ambient fire temperature rise exceeding +100 °C, the integrated fusible sensor automatically triggers a mechanical spring actuator, hermetically sealing gas flow in less than 60 seconds without external power.
Certified under DIN EN 331 and DVGW VP 305-1, these valves endure high-temperature fire exposure up to +650 °C for 30 minutes without leakage (thermal resistance rating GT5).
AZ INTEC medical gas distribution assemblies are fabricated in dedicated ISO Class 7 and ISO Class 8 cleanroom environments strictly adhering to DIN EN ISO 15001 standards.
All components undergo automated ultrasonic degreasing and dry nitrogen vacuum packaging, ensuring residual hydrocarbon levels strictly below 10 mg/m² for oxygen safety.
The H2-Ready product line utilizes customized high-nickel austenitic alloys (>12% Ni) and precision orbital micro-plasma welding, completely eliminating hydrogen embrittlement risks up to 700 bar.
Every production run of corrugated metal hoses, valves, and fittings at the Olbernhau manufacturing facility (Saxony) undergoes 100% hydrostatic pressure testing at 1.5 times rated working pressure.
Bellows assemblies and weld seams are verified using computerized helium mass spectrometer leak detectors with detection thresholds down to 1x10^-8 mbar·l/s.
Production processes operate under certified ISO 9001 and ISO 14001 quality systems and European Pressure Equipment Directive PED 2014/68/EU.
