Deeply committed to precision manufacturing, empowering overseas delivery! Recently, Jiutian Head achieved another success, successfully completing production and processing of a large hemispherical HHA 13500*40 low alloy steel head customized for a Russian customer and passing all acceptance tests. It is about to be shipped overseas to support the customer's high-pressure equipment project.

The head delivered this time is a high-pressure hemispherical head, a core component of pressure vessels. The 13500mm diameter specification imposes stringent standards on forming precision, material stability, and pressure-bearing performance. In response to the Russian customer's customization requirements, Jiutian Head strictly adhered to the customer's customization requirements and foreign trade export regulations, meticulously controlling the entire production process. From the selection of high-quality raw materials, precision molding, and professional heat treatment and correction, to dimensional calibration and appearance finishing, every process undergoes rigorous quality inspection. This process precisely overcomes technological challenges such as the ease of thinning and curvature deviation in the molding of large-size heads, ensuring the flatness, curvature accuracy, and structural strength of the products, and fully meeting the operating standards of high-end overseas equipment.
