Import Expansion Joint Bellows — Buy in Bulk from Supplier in China

Shandong Hengtong Expansion Joint Manufacturing Co, .Ltd produces expansion joint bellows designed to absorb thermal expansion, vibration and structural movement. The bellows are offered with a nominal diameter that can reach up to 20 000 mm and a wall thickness of 60 mm, providing substantial flexibility for large‑scale piping. A corrugation count selectable from 1 to 16 allows tailoring of stiffness and motion capacity to specific project requirements. The components are fabricated from industrial‑grade steel that meets general pressure and temperature resistance expectations.

While the listing does not state exact material grades, typical bellows in this class are made from ASTM A351 stainless steel or ASTM A252 carbon steel, offering corrosion resistance for oil‑gas and chemical environments. Industry practice commonly applies a pressure rating of up to 5 MPa and an operating temperature range of - 50 °C to 400 °C, which can be used as a baseline when evaluating suitability. Standard connection interfaces follow EN 13445 pressure‑vessel design or ANSI B16.5 flange dimensions, and wall thicknesses usually fall between 8 mm and 40 mm for similar diameters. The bellows can be supplied with customised end fittings to match existing pipeline configurations.

Buyers such as oil‑field contractors, chemical plant engineers and construction firms typically request these bellows for pipeline loops, HVAC ducts and heavy‑machinery assemblies. Confirm the minimum order quantity, lead time and preferred Incoterm directly with Shandong Hengtong, as the public data does not include those details. Request material certificates, pressure test reports and dimensional drawings to ensure compliance with project specifications before finalising the contract.

Shandong Hengtong Expansion Joint Manufacturing Co, .Ltd is located on Panhe Street, Taian, Shandong, China. The supplier is classified with a harbor trust tier and an imported tier status, and the public profile shows a zero percent response rate, meaning direct contact may be required for detailed queries. The company specialises in the production of expansion joint bellows and highlights the ability to customise dimensions and material composition according to client needs.

The supplier’s description notes that the bellows are engineered for flexibility and durability, suitable for oil and gas, chemical processing and construction applications.
