All weld-fabricated domed tank covers undergo comprehensive non-destructive testing (NDT), including radiographic testing (RT), penetrant testing (PT), magnetic particle testing (MT), and ultrasonic testing (UT), to ensure structural integrity and reliability.

During PT inspection, our technicians perform a highly detailed, segment-by-segment examination, carefully covering the entire surface to guarantee that even the smallest surface discontinuities are detected. This meticulous inspection process reflects our commitment to delivering safe, high-quality pressure components.

For welded heads, we typically produce stainless steel heads with diameters greater than 1.7 meters, and carbon steel heads with diameters greater than 2.1 meters. With advanced fabrication capabilities and strict inspection standards, we ensure that every product meets stringent customer specifications and performs reliably in high-pressure applications.

Henan Guojiang Precision Formed Head Co., Ltd maintains ASME-certified quality standards, complete manufacturing capabilities, strict quality control, and trusted professional industry engineers for daily production guidance.

Henan GJ Formed Head Factory is a benchmark manufacturer in China's precision pressure vessel component industry, with over 13 years of experience in R&D, production, and customization of dished heads. Its products are exported to more than 10 countries worldwide. In the field of core components for cryogenic tankers, ASME standards have always served as the foundation, with strict adherence to reliability and precision requirements, and providing solutions that meet the demanding working conditions of the global cryogenic transportation industry.

GJ Formed Head Factory provides value-added fabrication services for pressure vessel heads, including joggle forming (necking/closing-in), beveling (edge preparation), and laser hole opening processes, all performed strictly in accordance with customer drawings and technical requirements. These processes ensure precise fit-up, high welding quality, and improved assembly efficiency for downstream fabrication.

• Before packing into cartons or wooden cases, tank dished heads are wrapped and secured with protective cling film to ensure stability and prevent surface scratches.
• Products are then packed in cartons, wooden cases, or steel crates. Steel crates are mainly used for domestic delivery with our long-term logistics partners and are typically returnable to our factory for reuse.
• Standard shipping containers include 20' GP, 40' GP, and 40' HQ containers.
