Tube Sheets and Baffle Plates for A Large Seawater Desalination Plant

At Openex, we are thrilled to announce the successful manufacturing and shipment of tube sheets and baffle plates for a prestigious pressure vessel company. These critical components are destined to play a vital role in a groundbreaking project - the construction of China's largest seawater desalination plant.

Meeting the Challenge of Tube Sheets

The materials used for this batch of tube sheets are S32205 and S32304, totaling an impressive 328 pieces. Among them, 108 are tube sheets and 220 are baffle plates. What truly sets this project apart is the sheer scale of precision required – a staggering 4,175,432 holes needed to be drilled with utmost accuracy. Thankfully, we have harnessed the power of 31 sets of CNC drilling machines, ensuring the flawless processing of this critical batch.

The Large Desalination Plant

This extraordinary desalination plant consists of not one, but two desalination devices, each capable of producing an astounding daily output of 55,000 cubic meters of fresh water. These engineering marvels weigh a total of 3,440 tons and span an impressive 78 meters in length, 33.6 meters in width, and reach a towering height of 19.5 meters. With a total of 794,474 parts, it stands as China's largest seawater desalination plant with the most substantial single-machine capacity.

Our Team's Dedication

To expedite the completion of this monumental desalination plant, our marketing, production, technology, quality, and other departments united their efforts. Drawing upon our extensive experience gained from previous desalination projects, we meticulously planned every detail, implementing comprehensive checks at each stage and exercising precise control over every critical node. Through unwavering cooperation, we have successfully initiated batch shipments.

Client Satisfaction

Our clients have been quick to commend our processing equipment, our wealth of experience, and our robust service system. Their accolades reflect our steadfast commitment to delivering top-tier quality and exceptional service, even when confronted with the most significant engineering challenges.
