Weld neck, slip-on, blind, lap joint, and socket weld flanges are offered. Cast and forged with stainless steel, carbon steel, alloys and chrome steel, compliant with ASME, DIN, BS, JIS, GOST standard.
Long'an flange specializes in manufacturing various types of flanges and custom non-standard products. With over 100 CNC lathes and 10 machining lathes for heavy-duty processing, 16 high-precision machining centers, a comprehensive online ERP system, and an independent laboratory with 15 testing equipment, we guarantee superior service for our customers.
In making flanges, the raw materials are first tested with spectral detection. This process checks for impurities and ensures the materials are of good quality. It helps make sure the flanges are strong and meet industry standards.
The process begins with precision cutting that raw materials are cut into appropriate sizes. Then, they undergo forging to achieve the desired shape and strength. Next, rolling refines the shape further. Finally, CNC machines finish the flanges.
It involves using machining centers for shaping and high-speed drilling machines for creating holes. Machining centers handle cuts and shaping, while high-speed drilling machines ensure hole placement.
To insure the quality of flanges, we begin with spectral detection to analyze the material composition. After that, we conduct thorough inspection tests to verify the accuracy and durability.
Once the flanges are finished, they are stored in a warehouse. Then, they are packed for shipment. Logistics professionals handle their transportation, ensuring delivery to the intended use unit. Upon arrival, the flanges are ready for installation and operation.
The main role of flanges is to connect pipes and various equipment, making them a unified system. Flanges enable the transfer of fluids, gases, and solids, meeting the needs of production, manufacturing, and supply across various industrial sectors.
PIPELINE JUNCTION
Flanges can be used to connect pipes of varying sizes and materials. Since different equipment and pipes may have specific size and material requirements, using flanges helps connect them, ensuring fluid transfer between different pipelines.
VALVE & PUMP LINK
Flanges are widely utilized for connecting valves and pumps. Valves and pumps are integrated into these pipeline systems, and using flanges helps their installation and maintenance, thereby ensuring fluid control and transport throughout the system.
DISASSEMBLY & CARE
Using flanges allows for disassembly and maintenance of equipment and piping systems. When maintenance, replacement, or repairs are needed, loosening the flange bolts can separate the equipment from the piping. It minimizes disruption to the entire system.
