SS 316Ti Instrumentation Tube Fittings Manufacturer, Supplier and Exporter in India
Arrotop is a manufacturer, supplier and exporter of SS 316Ti Instrumentation Tube Fittings for chemical plants, petrochemical equipment, flue-gas systems, heat-processing units and welded instrumentation assemblies.
Our range includes SS 316Ti compression tube fittings, single ferrule fittings and double ferrule tube fittings for connecting tubing with valves, gauges, manifolds, transmitters, filters and other process instruments.
SS 316Ti is identified as UNS S31635 / EN 1.4571. It is a titanium-stabilised grade from the molybdenum-bearing 316 stainless steel family and is mainly specified for welded components and equipment exposed to elevated temperatures.
Arrotop supplies standard fittings, custom connections and replacement DIN 1.4571 fittings for OEM, project, plant maintenance and export requirements.
SS 316Ti Fittings for Welded and Heated Process Equipment
SS 316Ti is commonly used where instrument connections form part of welded equipment or remain close to heated process lines.
The titanium stabilisation makes the grade suitable for applications where welded stainless steel components face prolonged heat. It is often selected for flue-gas equipment, heated sampling lines, heat exchangers and process units already designed around EN 1.4571 material.
Typical requirements include:
- Welded chemical-processing skids
- Flue-gas analyser lines
- Heated sampling systems
- Heat exchanger instrument connections
- Petrochemical process equipment
- Instrument hook-ups on heated tanks and vessels
- Valve and manifold connections near hot lines

Features of SS 316Ti Instrumentation Tube Fittings
- Manufactured in SS 316Ti / UNS S31635 / EN 1.4571.
- Suitable for welded equipment and instrument lines exposed to prolonged heat.
- Handles elevated-temperature service better than standard SS 316L in many specified applications.
- Offers good corrosion resistance for compatible chemical and process media.
- Commonly used for flue-gas analyser lines, heated sampling systems, heat exchangers and petrochemical equipment.
- Available in single ferrule and double ferrule designs.
- In double ferrule fittings, the front ferrule forms the seal and the back ferrule grips the tube.
- Suitable for European and older equipment that specifically calls for DIN 1.4571 material.
- Grade marking and material certificates help confirm that the supplied fitting is SS 316Ti and not general SS 316 or SS 316L.

Typical applications include:
- Flue-gas analyser lines
- Heated gas and process sampling connections
- Chimney emission-monitoring lines
- Scrubber pressure and analyser connections
- Heat exchanger pressure gauge and transmitter hook-ups
- Instrument tubing on heated tanks and process vessels
- Welded chemical and petrochemical process skids
- Valve and manifold connections near heated equipment
- Furnace exhaust and combustion-monitoring lines
- Instrument connections on thermal-processing equipment
- European machinery specifying DIN 1.4571
- OEM instrument connections on imported process equipment
Arrotop supplies SS 316Ti connectors, elbows, tees, unions, bulkhead fittings, reducers and adapters for new installations, plant maintenance and project requirements. Share the fitting list, drawing, tube size, thread details and quantity for price and availability.
DIN 1.4571 Instrumentation Fittings for European and Existing Equipment
Many European machines, imported process skids and older industrial systems specify DIN/EN 1.4571 instead of UNS S31635.
For replacement or repeat orders, the fitting material should match the original specification. The RFQ, purchase order and material certificate should clearly mention SS 316Ti, UNS S31635 or EN 1.4571.
Arrotop supplies DIN 1.4571 Instrumentation Tube Fittings for:
- Imported chemical-processing machinery
- European analyser panels
- Existing SS 316Ti tube systems
- Valve and manifold assemblies
- Flue-gas and heat-processing equipment
- OEM repeat production
- Replacement of discontinued fittings
- Plant maintenance requirements
When the original part number is not available, share a drawing, a clear photograph or a physical sample for replacement matching.
SS 316Ti Fittings for Flue-Gas and Heated Sampling Lines
Flue-gas and heated sampling systems may require tube fittings near chimneys, scrubbers, ducts, heaters and thermal equipment.
Arrotop supplies SS 316Ti Instrumentation Fittings for flue-gas and heated sampling systems, including:
- Analyser line connectors
- Hot-gas sampling fittings
- Pressure and temperature instrument connections
- Scrubber monitoring lines
- Chimney instrument connections
- Filter and regulator hook-ups
- Valve and manifold tubing
- Heat exchanger monitoring lines
- Custom adapters for analyser panels
SS 316Ti is used in flue-gas applications and elevated-temperature equipment, which makes it a relevant material where the project specifically calls for this grade.
The required fitting still depends on the tube size, pressure, temperature, gas composition and thread connection.
Custom and Replacement SS 316Ti Fittings
Standard catalogue products do not always match older machines, imported panels or specially fabricated process equipment.
Arrotop manufactures custom SS 316Ti Instrumentation Tube Fittings from drawings, samples or required dimensions.
Custom requirements may include:
- Metric-to-imperial adapters
- NPT-to-BSP thread combinations
- Special reducing connectors
- Extended-body fittings
- Custom bulkhead connectors
- Gauge and transmitter adapters
- Reducer port connectors
- Special thread lengths
- Weld-end connections
- Non-standard body dimensions
- Customer part-number marking
- Repeat fittings for OEM equipment
For replacement enquiries, share the existing fitting photograph, tube OD, wall thickness, thread details, body dimensions and required quantity.
When a standard replacement is not available, Arrotop can check whether the fitting can be manufactured from the existing drawing or physical sample.
SS 316Ti Tube Sizes, Threads and Connections
SS 316Ti Instrumentation Tube Fittings are available for commonly used imperial and metric tubing.
Available size and connection options include:
- Imperial sizes from 1/16″ to 1½”
- Metric sizes from 1.5 mm to 38.1 mm
- Equal and reducing connections
- Tube-to-tube fittings
- Tube-to-male thread fittings
- Tube-to-female-thread fittings
- Bulkhead connections
- NPT male and female threads
- BSPT threads
- BSPP threads
- SAE and UNF threads
- Metric threads
- Special adapters against drawings
Mention the tube OD, wall thickness, thread standard and size in the RFQ. Arrotop supplies standard and custom SS 316Ti NPT connectors, BSPT adapters, BSPP fittings and metric compression tube fittings.
Pressure ratings vary with the fitting design, tube size, wall thickness, operating temperature and end connection.
SS 316Ti vs SS 316L for Welded and Heated Instrumentation Tubing Systems
SS 316Ti and SS 316L both belong to the molybdenum-bearing 316 stainless steel family, but engineers specify them for different service conditions.
SS 316L is commonly used in welded process equipment where a low-carbon stainless steel grade is required. SS 316Ti contains titanium and is often selected when the welded tubing system remains exposed to heat for long periods.
This makes SS 316Ti Instrumentation Tube Fittings for welded and heated tubing systems a suitable choice for flue-gas lines, heated sampling panels, heat exchangers, petrochemical equipment and European installations designed around DIN 1.4571.
SS 316Ti may also be required when replacing fittings in existing equipment where the original drawing, material certificate or project specification mentions UNS S31635 or EN 1.4571. Using a general SS 316L fitting may not meet the original material requirement.
Arrotop supplies SS 316Ti connectors, elbows, tees, unions, bulkhead fittings, ferrules and instrument adapters for standard and custom requirements. Share the fitting list, drawing, tube size and quantity for price and availability.
