Typical Application Cases of IFM E43300 (G1/2 Cone Hygienic Welding Adapter)

Principais vantagens: 1.4435 (316eu), Ra＜0.4 μm polished surface, G1/2 metal-to-metal cone seal, gasket-free dead-leg design, compatible with CIP/SIP. Matched with IFM PM15 pressure, TA flush temperature and LDL conductivity sensors.

Caso 1: Temperatura & Pressure Monitoring on Fermenters in Brewery (Indústria de Bebidas)

Condição de trabalho: Beer fermenter, tank wall thickness 2～3 mm, max internal temperature 95℃ (SIP steam sterilization). Medium contains yeast and wort, periodic CIP alkaline cleaning required.

Configuração: E43300 welding base + TA hygienic flush temperature sensor / PM15 hygienic pressure transmitter

Instalação: Drill holes on the side wall of fermenter, fully weld E43300 to tank body, polish inside and outside after welding. Sensors are screwed into G1/2 cone directly. No rubber gasket, avoiding aging and leakage after repeated high-temperature sterilization, as well as wort residue and bacterial growth.

Função: Real-time monitoring of fermentation temperature and tank pressure; dead-leg free for tank cleaning, compliant with EC1935 food hygiene regulation.

Caso 2: CIP Cleaning End-point Judgement by Conductivity in Dairy Batching Tank (Dairy Industry)

Condição de trabalho: Milk & cream mixing tank, CIP acid & alkali cleaning cycle. Conductivity is used to judge whether tank residue is fully flushed.

Configuração: E43300 + LDL200 hygienic conductivity sensor

Instalação: Weld E43300 on lower side wall of tank. Flush-mounted sensor avoids dead space for material accumulation.

Lógica de processo: Measure conductivity of cleaning fluid during cleaning. When conductivity drops to pure water threshold, CIP cleaning is deemed completed and the system automatically switches to next procedure.

Destaque: Polished tank base and flush-mounted sensor prevent adhesion of milk protein and shorten cleaning time.

Caso 3: Integrated Pressure & Temperature Monitoring in Biopharma Preparation Tank (Farmacêutico & Bioengenharia)

Condição de trabalho: Aseptic liquid preparation tank, batch SIP at 121℃ steam sterilization, zero residue & aseptic requirement, FDA material compliance.

Configuração: E43300 welding base + PM15 integrated temperature & pressure dual sensor

Instalação: Weld multiple E43300 on tank wall to monitor tank top pressure and liquid temperature respectively. Weld seam polishing and PT leak test are required after welding.

Valor: One base for both pressure and temperature measurement, reducing the number of tank openings. Metal-to-metal seal meets aseptic process with no risk of material leaching. 3.1 material certificate available.

Caso 4: Pressure Monitoring on Buffer Tank for Juice & Jam Pipeline (High-Viscosity Food)

Condição de trabalho: High-viscosity jam and fruit puree buffer tank. Medium is viscous and prone to sticking. Protruding sensor probe is not allowed to trap material.

Configuração: E43300 + PM15 flush diaphragm pressure sensor

Instalação: Weld E43300 on side wall of buffer tank. Flush diaphragm of sensor is level with inner tank wall.

Efeito: No protruding structure to accumulate high-viscosity medium. CIP flushing can achieve full cleaning. Monitor tank delivery pressure to control screw pump flow rate.

Caso 5: Hygienic Reactor in Fine Chemical Industry (Food Additive & Biosynthesis)

Condição de trabalho: Food additive reactor, batch high-temperature sterilization, weak acid & alkali medium, high corrosion resistance requirement for wetted material.

Configuração: E43300 + TA temperature sensor

Instalação: Weld E43300 on reactor side wall to monitor reaction temperature.

Observação: For reactor wall thickness＞3 mm, E43301 extended welding sleeve is preferred to prevent thermal deformation during welding and damage of internal cone sealing surface.

General Guidelines for Selection & Instalação

1. Sensor Matching: Must be IFM hygienic sensors with G1/2 external cone seal (PM15, ENFRENTANDO, LDL series). Ordinary G1/2 cylindrical threaded sensors are not compatible.
2. Welding Protection: Use a protective mandrel during welding to prevent thermal deformation of internal cone sealing surface. Do not bump the cone surface during post-weld grinding & polimento; scratches will cause leakage.
3. Model Selection Reference for the Series

E43300: Standard short version for tank wall ≤3 mm

E43301: Extended version for thick tank wall

E43302: G1/2 to G thread adapter

4. Domestic Substitution Tips: Ao substituir, verify cone angle, Ra polishing grade and material certificate. Ordinary G1/2 welded fittings adopt cylindrical thread instead of cone seal and cannot be directly replaced.

Material of IFM E43300 Welding Adapter

Wetted body material: 1.4435 (316eu) aço inoxidável

1.4435 is low-carbon austenitic stainless steel with slightly higher molybdenum content than standard 1.4404. It has better resistance to pitting and crevice corrosion, and is the preferred grade for sterile processes in pharmaceutical and food industries.

Tratamento de superfície

Wetted surface mechanical polishing: Ra＜0.4 μm, Rz=4 μm, dead-leg free, resistant to repeated CIP/SIP cleaning & sterilization.

Material Differentiation of IFM Hygienic Welding Adapters in the Same Series

1. E43300 / E43301 / E43309: 1.4435 (316eu), high-grade hygienic type, preferred for pharmaceutical & fermentation applications
2. E43375: 1.4404 (also 316L), for general food & beverage applications, slightly lower corrosion resistance than 1.4435

Both are classified as 316L, mas 1.4435 has lower ferrite content, better weldability and higher intergranular corrosion resistance. 3.1 material certificate of 1.4435 is usually required for sterile projects.

Notas Suplementares

The adapter body is machined from solid stainless steel bar/forging, no rubber components. Sealing relies on metal-to-metal cone mating of G1/2 thread, no gasket needed.

Material compliance: Compliant with EC1935 food contact materials, material test certificate available.

Dica de seleção

For domestic substitution, do not simply specify “316eu”. Drawings and purchase orders shall clearly state: Aço inoxidável 1.4435, wetted surface polished Ra≤0.4 μm, otherwise suppliers may substitute with 1.4404.

📎 Substitution Information

Alternativa doméstica: 316L hygienic G1/2 cone welding base Φ30. Key verification items: cone angle, Ra polishing grade, material certificate.

⚠️ Nota: Ordinary G1/2 threaded fitting ≠ cone seal. Different sealing structure prevents direct replacement.

Installation Dimensions of IFM E43300 Welding Adapter (Unidade: milímetros)

E43300: Tank hygienic welding sleeve, G1/2 internal cone seal, 1.4435 aço inoxidável

✅ Core Installation Dimensions

1. Outer diameter of welding sleeve: Φ30 (critical dimension for tank welding)
2. Recommended tank hole diameter: Φ30, prepare welding bevel on hole edge

E43300 for tank wall ≤3 mm; E43301 extended version for tank wall＞3 mm

3. Internal thread on sensor side: G1/2 (BSPP parallel thread with 45° metal cone seal)

⚠️ Not standard plain G1/2 cylindrical thread. It is cone metal-to-metal sealing structure, only compatible with IFM hygienic sensors with G1/2 external cone (PM15, ENFRENTANDO, LDL).

4. Overall body height (comprimento): 20 milímetros (from welding face to top of adapter)
5. Inner bore: G1/2 threaded hole with machined sealing cone at bottom
6. Peso: Aprox.. 164 g

📌 Dimension Comparison of Models in Same Series (for selection)

🛠️ Field Installation Guidelines

1. Tank wall hole: Φ30, prepare welding bevel. Fully weld the outer wall of adapter to tank body. Polish inner tank weld seam after welding to ensure Ra＜0.4 μm and dead-leg free.
2. Montagem embutida: Inner face of adapter shall be flush with tank inner wall, no protrusion or depression to avoid material accumulation.
3. Welding protection: Protective mandrel (E43922) must be inserted during welding to prevent thermal damage to G1/2 internal cone sealing surface. Scratches on cone surface will lead to metal seal leakage.
4. Sensor screwing: External cone of sensor mates with internal cone of adapter for metal-to-metal sealing, no gasket required.

📎 Drawing Remarks (for machining & domestic substitution)

Outer circle Φ30; altura 20; internal G1/2 thread with sealing cone; wetted material 1.4435; wetted surface polishing Ra≤0.4 μm.

For domestic machining substitution, cone angle is critical. Ordinary G1/2 threaded fittings have no matching cone and cannot achieve sealing.
