Custom DN350 Flanged Metal Hose Solution for High-Temperature Exhaust Gas Pipelines
Case Background:
A Turkish cement and chemical facility faced an emergency operational shutdown after a low-quality metal hose failed under high-temperature exhaust conditions, causing severe outer braid swelling. Runtaida provided a rapid custom-engineered replacement solution to restore plant operations and mitigate staggering daily downtime losses.
Engineering a High-Performance Stainless Steel Flexible Hose Solution
Recognizing the urgency, the client contacted Runtaida. Our engineering team immediately analyzed the application's rigorous working parameters to design a robust, custom-engineered solution:
Product Type: Heavy-duty Stainless Steel Flexible Hose with Carbon Steel Flanges (Flanged Metal Hose)
Nominal Diameter: DN350 (14 Inch Large Bore Metal Hose)
Installation Length: 4000 mm (4 Meters)
Working Medium: Flame / High-Temperature Exhaust Gases
Operating Pressure: 10 Bars (PN10)
Maximum Working Temperature: 440 °C (Ultra High-Temperature Resistance)
Application Site: Industrial Cement and Chemical Processing Facility (Turkey)
Why Quality Matters in High-Temperature Industrial Piping
For extreme applications involving flames and 440°C operating temperatures, standard hoses simply cannot survive the thermal expansion and high vibrations. Runtaida's customized DN350 metal flexible hose features multi-layer corrugated stainless steel reinforced with high-density wire braiding. This design guarantees superior pressure containment, maximum flexibility, and absolute leak-proof reliability under severe thermal stress.
The high-quality flexible hoses passed strict pressure tests, were securely packed, and were shipped ahead of schedule to minimize the client's plant downtime.

Industrial Metal Hose FAQ (Frequently Asked Questions)
Q1: What caused the initial metal flexible hose to fail and bubble in this high-temperature pipeline?
A: Premature bubbling and braid failures are typically caused by selecting substandard stainless steel materials, poor welding quality between the corrugations and the braiding, or miscalculating the pipeline's thermal expansion and high-frequency vibrations.
Q2: What is the maximum temperature and pressure a Runtaida flanged metal hose can withstand?
A: Our customized stainless steel flexible hoses can safely operate in extreme environments with temperatures reaching up to 440°C (and higher with specialized alloys) and working pressures exceeding 10 Bars (PN10/PN16), making them ideal for heavy industrial exhaust and steam systems.
Q3: How do large-bore metal hoses (like DN350 / 14 Inch) absorb thermal expansion in cement plants?
A: Large-bore corrugated metal hoses act as flexible expansion joints. Their multi-layer corrugated design allows them to flex and absorb axial, lateral, and angular movements caused by extreme thermal cycles, protecting the rigid piping system from cracking or leaking.
