Our company produces stainless steel welding pipes for power plant condensers, available in diameters from Φ14mm to 40mm and wall thicknesses from 0.5mm to 2.0mm, with a full range of varieties. The raw materials used are steel strips of grades TP304 and TP316. We process and manufacture according to ASTM standards and manage comprehensively under the ISO9001 quality system, strictly controlling product quality to ensure customer satisfaction and peace of mind. The company boasts a team of continuously advancing R&D professionals, consistently developing new products and varieties to meet customer and market demands.
Pipe Replacement Project
The condenser is a crucial cooling equipment for steam turbine generators. The pollution from the Gan River and Xiang River systems accelerates the corrosion rate of the condenser tubes, leading to frequent leaks and severely impacting normal production. Particularly, copper tubes are prone to corrosion by radon ions and halides, causing leaks. Additionally, the rough inner walls of copper tubes facilitate the attachment of microorganisms and various dirt, significantly reducing their service life.
Our company has established a professional机械化管路更换工程队, specializing in the removal of old and installation of new tubes for various heat exchangers such as the condenser, high and low-pressure heaters, thermal network heaters, oil coolers, and water coolers, all made of stainless steel, copper, and titanium.
Our company has developed an advanced tube replacement process through years of practice in condenser tube replacement. We have a strong reputation in this field, with our services covering most power plants across the country and receiving positive feedback numerous times.
The installation team is equipped with all types of specialized machinery and tools required for pipe removal, expansion, threading, cutting, and cleaning in tube replacement projects. We are capable of handling tube replacement installation for various heat exchangers, characterized by short project duration and high quality.
We also undertake the manufacturing of new condensers and the engineering to increase the heat exchange area of existing condensers without moving the outer shell (which involves removing all components such as end plates and baffles from the old condenser, redesigning the piping layout based on the required additional area, and re-manufacturing the end plates, baffles, and other parts as needed).
Technical Advantages:
现场 machined slot expansion jointing for tube plates (no slot required for copper tubes, direct expansion jointing), ensuring the heat exchange tube pull-out force exceeds 1000 kg.
Flanges and flange holes restored to new condition; no burrs on flange holes.
Proper expansion rate, neither under nor over-expanded, ensures the expansion joint remains tight and leak-proof over a long period.
Independent series specialized pipe exchange tools, practical, efficient, and durable.
Mature and extensive on-site pipe replacement experience.
Professional pipe replacement team with specialized training
High-quality, efficient, and completed within a short cycle.
Condenser cooling tube material selection and operation maintenance consultation.
During construction, it is possible to replace pipes in large quantities and quickly, as well as individually or in specific sections.
