Products Description
This series of large diameter metal hoses is integrally molded with thickened stainless steel plates, featuring regular corrugation arrangement, uniform wall thickness and high structural strength. It can withstand high-flow fluid impact and high-pressure load without bulging, deformation or fracture. The smooth and transparent inner wall reduces flow resistance and avoids material accumulation dead angles, ensuring smooth medium transmission and stable flow for large-diameter pipelines. The flanges and joints at both ends adopt integral welding and forging technology with full and dense welds and strong pressure tightness, preventing interface leakage, welding detachment and falling off under high pressure conditions. With excellent flexible stretching, vibration damping and displacement compensation performance, it adapts to complex working conditions such as pipeline settlement, alternating cold and hot deformation and high-frequency equipment vibration. Complete large-diameter specifications and non-standard customization meet the flexible pipeline connection needs of various large industrial equipment, municipal engineering and heavy-duty fluid transmission systems.

Product Q&A
Q: What scenarios are large diameter metal hoses suitable for?
A: It is mainly applicable to high-flow, large-diameter and high-pressure heavy-duty transmission working conditions, widely used in municipal water supply and drainage engineering, large-scale chemical fluid pipelines, metallurgical and power equipment, heavy machinery, boiler steam systems and large pump valve supporting pipelines. It specially solves the problems of vibration, thermal expansion, installation deviation and high-pressure leakage of large-diameter pipelines, serving as a special flexible accessory for heavy-duty industrial pipeline systems.
Q: Will large diameter metal hoses leak under high pressure?
A: No. Adopting thickened pipe structure and precision integral welding technology, the weld is dense without pores and cold solder joints with high overall pressure resistance. The flat sealing surface of flanges and joints ensures tight fitting, which can withstand long-term conventional industrial high-pressure impact without structural deformation or interface loosening. Standard installation completely avoids high-pressure leakage.
Q: Can you customize super-large diameter and non-standard products?
A: Full-range non-standard customization is supported. Relying on 500+ sets of molds and a professional ODM engineer team, we can customize large diameter metal hoses with super-large calibers, special lengths, special-shaped joints and special pressure requirements according to customers' CAD/PDF/STEP drawings, on-site working conditions and equipment parameters, meeting differentiated supporting needs of various large-scale projects.
