What is the construction process of biogas desulfurization and what are the steps? In fact, it mainly includes seven steps, which many people are not clear about. In this article, we will introduce step 1: Survey and lofting.
The specific process of biogas desulfurization includes: Surveying and setting out - cylinder wall rolling - primary anti-corrosion - cylinder joint assembly - tower bottom assembly - tower body assembly - overall anti-corrosion.
Introduction to the steps of Surveying and setting out:
1. The selected materials and accessories shall have quality certificate and comply with the current national regulations. The steel plate and accessories shall have clear product identification. Check whether it meets the design requirements. The appearance of steel plates shall be inspected one by one, and the quality shall comply with the current relevant national steel plate quality standards. The sum of the local surface thinning, scratch depth and the actual negative deviation of the steel plate shall not be greater than the standard negative deviation of the corresponding steel plate.
2. According to the specification, the appearance quality and size of the material shall be sampled, and the sampling inspection shall be doubled in case of non standard products. If the re inspection is unqualified, the supplier shall be informed to return the goods.
3. The selection of welding materials (welding rods) shall meet the design requirements, have quality certificate and meet the requirements of the current national quality standard carbon steel welding rod (GB / t5117).
4. Steel plate size inspection: the allowable deviation of length and width is less than 1.5m; The allowable deviation of diagonal difference is 3mm; The allowable deviation of straightness on both sides of the board is 1m.
