Product Specifications and Manufacturing Quality Control
LSAW EN10219 610mm carbon steel pipes are suitable for regional geothermal heating trunk networks, demanding high standards for pressure-bearing capacity, cross-sectional stability, and long-term operational reliability. Huayang possesses a mature production and quality control system for 610mm large-diameter longitudinal seam steel pipes. From the initial receipt of various base materials such as Q235B and S355J2, we implement chemical composition verification, plate ultrasonic testing, and thickness precision measurement. The forming process employs UOE or JCOE technology, ensuring the 610mm diameter's roundness, straightness, and weld overlap are maintained within stringent tolerances. Double-sided submerged arc welding guarantees uniform weld metal microstructure free from slag inclusions. Finished pipes undergo dimensional inspection, 100% UT testing, and hydrostatic pressure testing per EN10219, making them suitable for long-term stable operation under high-temperature, high-flow conditions of geothermal water systems.
Performance in geothermal heating main network systems
The 610mm specification is commonly employed in regional distribution sections of urban district heating networks or as primary transmission pipelines between geothermal wellfields and heat exchange stations. It meets the demands of sustained conveyance for high-flow, high-temperature geothermal water or thermal carrier fluids. Geothermal systems typically exhibit characteristics such as high mineral content in water and significant temperature fluctuations. Huayang offers tailored solutions including internal epoxy coatings, double-layer fusion-bonded epoxy, or triple-layer PE external anti-corrosion for specific operating conditions, enhancing corrosion resistance and insulation layer adhesion. The 610mm large diameter reduces pressure loss while lowering pumping energy consumption, thereby improving thermal energy transmission efficiency. With precise end beveling and excellent weldability, this product facilitates on-site integration with compensators, valve assemblies, and insulation structures, making it a key piping solution for ensuring the stability of urban geothermal heating networks.
