Import Expansion Joint — Buy in wholesale FOB from Supplier in China

The expansion joint offered by Shijiazhuang Jully Science & Technology Co., Ltd is a marine‑grade unit intended for shipboard piping systems with DN 100 mm flanges. It is available in nominal diameters from 8 mm up to 10 000 mm and wall thicknesses between 0.15 mm and 70 mm. Construction materials include carbon steel, duplex steel, stainless steel grades 304 and 316, Hastelloy, titanium, zirconium and nickel alloys. The joint tolerates pressures from - 10 MPa to +10 MPa and operates across a temperature span of - 196 °C to 1 400 °C, with U and V shapes produced by hydraulic, roll and press‑brake forming.

Carbon steel provides cost‑effective strength for low‑temperature service, while the stainless and nickel alloy options meet the corrosion resistance demanded by seawater and chemical exposure. Duplex steel and Hastelloy are typical choices for higher chloride environments, and titanium or zirconium are selected when ultra‑low weight or extreme corrosion resistance is required. In the broader industry, expansion joints of similar size range are standard for marine propulsion, heat‑exchanger loops and offshore power plant piping. The supplied pressure rating of ±10 MPa exceeds the typical - 5 to +5 MPa range found in many commercial marine joints, offering additional safety margin.

Typical buyers include shipbuilders, offshore platform contractors and maintenance yards that need to compensate thermal growth and vibration in high‑pressure lines. The product is listed for global export, but the supplier does not disclose minimum order quantity, lead time or incoterm details, so interested parties should request these terms directly. Because the response rate is currently recorded as zero, confirming communication channels before placing an order is advisable. All technical data should be verified against the buyer’s design specifications prior to procurement.

Shijiazhuang Jully Science & Technology Co., Ltd is located in the Xinzhaidian Industry Area of Zhao County, Hebei Province, China. The company is classified as an imported tier supplier and holds a harbor trust tier, indicating a moderate level of verification on the platform. Its response metrics show a 0 % response rate with no average response time recorded, suggesting that direct contact is required to assess current communication performance.

The catalogue entry focuses on marine‑grade expansion joints covering a wide material palette and size spectrum. No additional product lines or certifications are mentioned in the listing, and the supplier does not provide explicit production capacity or quality management system details. Prospective importers should request material test certificates and manufacturing process information to confirm compliance with project standards.
