Boiler tube cleaning brushes are specially designed tools used to clean the inside of boiler tubes, heat exchangers, and condenser tubes. These brushes help remove soot, ash, scale, and deposits to improve boiler efficiency and heat transfer.
They are typically made with steel wire, nylon, or brass bristles, depending on the cleaning needs.
Â
Key Features:
- Brush Types:
- Steel wire – for hard deposits and heavy cleaning
- Nylon – for soft cleaning and non-metallic tubes
- Brass – for gentle cleaning of soft metals (like copper)
- Body Materials: Steel or plastic core
- Connection Types: Threaded (to fit rods), loop, or universal
Applications:
- Boiler maintenance
- Heat exchanger cleaning
- Condenser and chiller tube cleaning
- Industrial plant maintenance
- HVAC system servicing
Available Sizes:
Brush sizes are based on the inner diameter (ID) of the tubes. Common sizes include:
| Brush Diameter |

Product Description:
A disc check valve made from SS304 stainless steel is a compact, non-return valve designed to allow flow in one direction and prevent backflow. It uses a spring-loaded disc that opens with forward flow and closes when flow reverses.
It is durable, corrosion-resistant, and suitable for various liquids, gases, and steam applications.
Key Features:
- Material: Stainless Steel 304 (SS304)
- Type: Spring-loaded disc (non-return)
- Design: Wafer type (compact & space-saving)
- Working Pressure: Up to 16 bar (varies by model)
- Temperature Range: Up to 200°C (approx., depending on seal material)
- Installation: Horizontal or vertical (upward flow)
- Ends: Wafer type (fits between flanges)
Applications:
- Water and wastewater systems
- HVAC and chilled water lines
- Chemical and process industries
- Steam lines
- Food & pharma systems
- Compressed air and gas lines

This valve protects a pressure system by automatically opening when the pressure exceeds a preset limit, allowing fluid to discharge freely into open atmosphere (or safe vent) rather than into a downstream piping system.
Key Features
-
Open Discharge Outlet: When the set pressure is exceeded, the valve vents the excess pressure directly to the outside (ambient) rather than into a downstream pipe.
-
Spring‑loaded Mechanism: A calibrated spring holds the valve shut under normal pressure. Once the pressure exceeds the set value, the spring is overcome and the valve opens.
-
Manual Adjustment / Setting: The set pressure can typically be defined at installation (or factory‑set).
-
Re‑seating Ability: Once pressure drops back below a set threshold (blow‑down), the valve closes again to prevent further discharge.
-
Compact Connection: Commonly screwed or flanged inlet; outlet is free.
-
Applications: Air/gas compressors, pressure vessels, general industrial systems where over‑pressure protection is required and discharge to atmosphere is acceptable.
Typical Sizes Available
Typical Spec Limits
-
Set‑pressure range: e.g., 0.5 bar g up to ~10 bar g (varies by model)
-
Maximum allowable temperature: depends on materials, e.g., up to ~180 °C or more
-
Material: brass or steel body, corrosion‑resistant internals

This is a compact spring‑loaded safety/relief valve made by UTAM, designed for installation in piping systems to protect against over‑pressure. It features an angle configuration (inlet and outlet form approximately a 90° angle) and screwed threaded ends for easy connection.
 Key Features
- Angle‑type design: Inlet and outlet form a bend (~90°), which helps in tight or compact piping layouts.
- Screwed ends: Threaded connections (e.g., BSP/NPT) — easy to install in standard threaded piping.
- Spring‑loaded operation: The valve remains closed under normal pressure, and opens automatically when pressure exceeds a preset set value, venting the excess fluid/gas.
- Re‑closing ability: After pressure drops back below the set threshold, the valve resets and stops the discharge.
- Reliable construction (UTAM brand): Made with robust materials (body, spring, disc/seat) and designed for industrial applications such as boilers, vessels, pipelines.
- Standard specification features:
- Set‑pressure range from roughly 0.5 bar up to about 10 bar for their typical screwed models.
- Max operating temperature around 200‑225 °C (depending on version) and capable of body test pressures (e.g., 24 bar) in their datasheet.
- Sizes in the UTAM offering: 15mm (½″ BSP), 20mm (¾″), 25mm (1″), 32mm (1¼″), 40mm (1½″), 50mm (2″) for their standard safety valve line.
Typical Sizes (Threaded / Screwed Version)
- ½″ (15 mm)
- ¾″ (20 mm)
- 1″ (25 mm)
- 1¼″ (32 mm)
- 1½″ (40 mm)
- 2″ (50 mm)
Typical Applications
- Boilers and pressure vessels
- Piping lines carrying steam, air, water, gas
- Process industries including chemical, pharmaceutical, food
- Protection of pumps, compressors, and other pressurized systems
