Our stainless steel bellows are precision-engineered from high-grade austenitic and duplex stainless steels (304, 316L, 321, 2205, etc.), offering exceptional flexibility, pressure resistance, and corrosion stability. Designed to compensate for thermal expansion, vibration, and misalignment in piping systems, these bellows feature multi-ply construction (1-8 layers) and customized convolution profiles. Available in a full range of standard sizes with wide working pressure and temperature adaptability. Compliant with EJMA, ASME B31.3, and ISO 10380 standards, ideal for chemical, petrochemical, power generation, HVAC, and water pipeline systems.

The stainless steel hose production line is equipped with fully automatic welding units, precision forming equipment, pressure resistance testing systems, and surface treatment lines, enabling refined full-process production from raw material cutting, forming, and welding to pressure testing, polishing, and packaging. Strictly adhering to international standards such as ASTM and DIN, each batch of products undergoes leak testing and temperature resistance performance testing to ensure stable operation in various harsh environments and efficiently meet customers' bulk order and customization needs.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
