KIDY supplies JIS G3463 stainless steel pipes designed for heat-transfer and high-temperature equipment, including boilers, heat exchangers, condensers, instrument lines, and finned-tube systems. KIDY is a service-oriented enterprise with conventional steel grades and long-term availability of raw materials and semi-finished heat exchanger tubes. We can produce specifications and pressures according to customer needs. The length can reach 24 meters and can be cut according to customer length requirements. For buyers comparing steel tube manufacturers, we provide flexible grade, dimension, surface, and length options to match different operating and fabrication requirements.
Wide dimensional range: Available in outside diameters from 3 mm to 219.1 mm and wall thicknesses from 0.5 mm to 20 mm.
Multiple stainless steel grades: Common austenitic, ferritic, duplex, heat-resistant, and corrosion-resistant grades can be supplied according to JIS G3463 requirements and project specifications.
Cold-finished production: Cold drawing and cold rolling help achieve controlled dimensions and surfaces suitable for heat exchanger and boiler tube applications.
Surface finish options: Pipes can be supplied with pickled or bright-finished surfaces based on fabrication and service requirements.
Custom lengths up to 24 meters: Long-length tubes help reduce the number of joints in equipment and piping systems. Cutting to specified project lengths is also available.
Flexible production support: Conventional grades are supported by stable raw-material and semi-finished tube availability, allowing KIDY to accommodate customized dimensions, quantities, and delivery requirements.
Send us the required grade, outside diameter, wall thickness, length, surface finish, quantity, and applicable inspection requirements to receive a project-specific quotation.
Customer Satisfaction Is Our Honor. Feel free to enquiry us any questions of pipeline materials.
