沼气脱硫的测量和放样是怎样的?

沼气脱硫的具体过程包括:测量放样-鼓壁碾压-一次防腐-鼓接头组装-塔底组装-塔体组装-整体防腐。

The specific process of biogas desulfurization includes: Measurement and setting out - drum wall rolling - primary anti-corrosion - drum joint assembly - tower bottom assembly - tower body assembly - overall anti-corrosion.
测量放样步骤介绍:
Introduction to survey and setting out steps:
1.所选用的材料和附件应具有质量证书,并符合现行规定。钢板和附件应有清晰的产品标识。检查是否符合设计要求。钢板应逐个进行外观检查,其质量应符合现行的钢板质量标准规定。钢板的局部减薄量、划痕深度和实际负偏差之和不应大于相应钢板的标准负偏差值。
1. The selected materials and accessories shall have quality certificates and comply with the current regulations. Steel plates and accessories shall have clear product identification. Check whether it meets the design requirements. The steel plates shall be visually inspected one by one, and their quality shall meet the provisions of the current steel plate quality standard. The sum of local thinning amount, scratch depth and actual negative deviation of steel plate shall not be greater than the standard negative deviation of corresponding steel plate.
2.根据规格对材料的外观质量和尺寸进行抽查,如发现不合格产品,加倍抽查。如果复检不合格,通知供应商退货。
2. Spot check the appearance quality and size of materials according to the specifications. If unqualified products are found, double the spot check. If the re inspection is unqualified, notify the supplier to return the goods.
3.焊接材料(焊条)的选择应符合设计要求并有质量证明书,质量证明书应符合现行质量标准《碳钢焊条》GB/T5117的要求。
3. The selection of welding materials (welding rods) shall meet the design requirements and have quality certificates. The quality certificates shall meet the requirements of the current quality standard carbon steel welding rods (GB / t5117).
4.钢板尺寸检验:长宽允许偏差1.5m对角线之间的允许偏差为3毫米;;板材两侧直线度允许偏差为1m。
4. Dimension inspection of steel plate: the allowable deviation of length and width is 1.5m, and the allowable deviation between diagonals is 3mm;; The allowable deviation of straightness on both sides of the plate is 1m.
