GR1 U bend
Product overview
This product selects industrial pure titanium (GR1) as the raw material, giving full play to the excellent thermal conductivity and extreme corrosion resistance of titanium. In response to the heat exchange needs of shell and tube heat exchangers, evaporators and condensers, GR1 U-shaped tube bends effectively solve the problems of medium flow-induced vibration and thermal stress compensation through the unique cold forming process. The product can operate stably for a long time in harsh working conditions such as high chloride ions, acidic medium, high temperature and high pressure, and is an ideal choice for heat exchange systems in marine engineering, petrochemical, chlor-alkali industry and thermal power generation.
Core advantages
Extreme corrosion resistance: GR1 material is naturally immune to chloride, seawater and oxidizing acids, and its resistance to pitting, crevice corrosion and stress corrosion cracking far exceeds that of traditional stainless steel.
Efficient heat transfer: Titanium's unique surface activity and customizable surface treatment process can significantly improve heat transfer efficiency and reduce system energy consumption.
Excellent technology: The advanced pipe bending process is used to strictly control the thinning rate and ovality to ensure that the internal flow path of the tube bundle is smooth and can perfectly match the layout of the tube plate.
Technical standards
We strictly implement the dual quality control system of international and national standards to ensure that every U-shaped bend is traceable. Product production and acceptance are carried out according to the following standards:
American Standard: ASME SB338 (Titanium and Titanium Alloy Seamless/Welded Pipe Specification)
National standard: GB/T 3625 (titanium and titanium alloy tubes for heat exchangers and condensers)
.
Quality assurance deliverables
Complete material certificates, dimensional test reports, and surface inspection records are provided with the goods to ensure the compliance and traceability of the entire process of products from raw materials to finished products.
Surface treatment
To optimize heat transfer efficiency and adapt to the adhesion characteristics of different media, we offer a variety of surface treatment options:
Regular state: pickled surface. Removing the oxide scale, showing the natural color of the metal, high cleanliness, suitable for most working conditions.
Customization Options:
Mechanical polishing: Reduces surface roughness and reduces the tendency of dirt to adhere, suitable for scaling media.
Sandblasting: Achieve a uniform matte finish that improves adhesion in painting or subsequent processes.
Connection form
Considering the convenience of system integration and sealing reliability, the straight pipe section can be precision machined according to the requirements of the design drawings:
Welding bevel: Process V-shaped or U-shaped bevels according to standards to ensure the quality of on-site group welding.
Thread interface: customize internal and external threads according to customer needs to achieve quick disassembly and assembly.
Flange Connection: Adapted to standard flanges to meet the sealing needs of high-pressure or frequent maintenance scenarios.
