OUR SERVICES
Bond Asia Limited Partnership
“Blond Asia Limited Partnership provides professional maintenance and overhaul services for sootblowers and valves across various heavy industries, including petrochemical plants, petroleum refineries, conventional power plants, and biomass power plants.”
Bond Asia Limited Partnership provides valve maintenance and repair services, including the supply of spare parts. With over 20 years of experience in valve maintenance, we have a maintenance workshop located in the Map Ta Phut Industrial Estate and can perform valve overhaul services nationwide / onsite / onshop.
Sootblower repair is not just about cleaning and polishing, but about “reducing loss and increasing efficiency” for our customers.
SHOOTBLOWER
Focus on preventative checks to reduce the chances of boiler shutdowns (which cost millions of baht per day).
“A Sootblower Overhaul is a critical preventive and major maintenance procedure for boilers in power plants and industrial facilities. It ensures the sootblowing system operates at peak efficiency, prevents mechanical jamming, and minimizes the risk of boiler tube damage.”

Sootblower Overhaul Process
A Sootblower Overhaul is a critical preventive and major maintenance procedure for boilers in power plants and industrial facilities. It ensures the sootblowing system operates at peak efficiency, prevents mechanical jamming, and minimizes the risk of boiler tube damage.
The overhaul process is generally divided into 4 main stages:
1. Pre-Overhaul & Inspection
Prior to disassembly, the current operational status is assessed to diagnose existing issues.
Visual & Operational Check: Inspect the equipment during operation to detect abnormal noises, vibrations, or steam leakages.
System Isolation: Implement full Lockout/Tagout (LOTO) procedures and isolate the main steam supply valve to ensure 100% safety before work begins.
Lance Tube Alignment Check: Inspect the straightness of the lance tube for any bending or warping.
2. Disassembly & Cleaning
Once the system is safely isolated, major components are dismantled for detailed inspection and cleaning.
Drive & Carriage Assembly Removal: Disassemble the electric motor, gearbox, and carriage assembly.
Lance Tube & Feed Tube Removal: Carefully support and remove the lance tube from the front support, and dismantle the internal steam feed tube and poppet valve.
Thorough Cleaning: Clean off old grease, soot, and debris from all parts using solvents or sandblasting where appropriate to expose the bare metal surface.
3. Inspection & Component Renewal
The core of the overhaul involves measuring and evaluating components against OEM specifications.
Gearbox & Motor: Replace gear oil, inspect gear teeth backlash, and replace all bearings and oil seals.
Poppet Valve Servicing: Perform valve lapping on the valve seat to prevent steam leakage, which is a primary cause of boiler tube erosion.
Lance Tube & Nozzle Inspection: Check for wear, wall thickness, and cracks—especially around the nozzles. Components falling below standards are repaired or replaced.
Sealing & Gasket Replacement: Renew all stuffing box packings and high-temperature gaskets to prevent steam leaks during extension and retraction.
Drive Mechanism: Inspect and replace worn drive chains, rollers, and tracks.
4. Reassembly & Commissioning
Reassembly: Rebuild all components, adjust chain tension, and apply high-temperature grease to all rotating parts and bearings.
Alignment: Align the lance tube precisely with the wall box to ensure smooth travel without friction or jamming.
Cold Test (Dry Run): Energize the system to test the travel of the sootblower, verifying that the limit switches trip accurately.
Hot Test (Steam Commissioning): Introduce steam to test real-world operation, verify nozzle popping pressure, and ensure zero leakage at all joints and the poppet valve.

GADE VALVE
Gate valves are ideal for applications where the valve is either rarely used or remains open/closed for long periods
GLOBE VALVE
Globe valves are typically used in systems where flow control and leak tightness are critical,
BALL VALVE
It is best used for on/off applications rather than throttling (controlling flow volume), as keeping the valve partially open can damage the internal seats over time.
CONTROL VALVE
A Control Valve is an automated valve used to precisely manage fluid flow, pressure, temperature, or liquid level within a system.
SAFETY VALVE
A Safety Valve is a specialized device designed to protect a pressurized system (like a boiler, pressure vessel, or piping) from exploding or failing due to excessive internal pressure
BUTTERFLY VALVE
Butterfly valves are widely used in water supply, wastewater treatment, and fire protection systems, as well as in chemical and food processing industries where large volumes of fluid need to be managed efficiently.
