沼氣的脫硫施工流程是怎樣的，包含哪幾個步驟？其實主要包含七個步驟，很多人對此都是不清楚的，本篇文章我們?yōu)榇蠹医榻B步驟一：測量放樣。
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.
沼氣的脫硫具體流程包括：測量放樣---筒壁卷制--初級防腐--筒節(jié)組對---塔底組裝--塔體組裝- 整體防腐。
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.
測量放樣的步驟介紹：
Introduction to the steps of Surveying and setting out:
1、選用的材料和附件要具有質(zhì)量合格證明書并符合相應(yīng)的國家現(xiàn)行規(guī)定鋼板和附件上應(yīng)有清晰的產(chǎn)品標識。查看是否符合設(shè)計要求。鋼板應(yīng)逐張進行外觀檢查其質(zhì)量應(yīng)符合國家現(xiàn)行有關(guān)鋼板質(zhì)量標準規(guī)定。鋼板表面局部減薄量、劃痕深度 與鋼板實際負偏差之和不應(yīng)大于相應(yīng)鋼板標準負偏差值。
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、根據(jù)規(guī)范對材料的外觀質(zhì)量和尺寸進行抽檢,如發(fā)現(xiàn)不臺格品應(yīng)加倍抽檢。復(fù)檢不合格時,通知供貨單位作退貨處理。
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、焊接材料(焊條)選擇應(yīng)符合設(shè)計要求并具有質(zhì)量合格證明書,符合國家現(xiàn)行質(zhì)量標準《碳鋼焊條》GB/T5117的要求。
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.鋼板尺寸檢查:長度和寬度允許偏差士1.5m ；對角線之差允許偏差3mm；板兩邊直線度允許偏差土1m。
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.
關(guān)于沼氣的脫硫放樣檢測流程我們已經(jīng)介紹給大家了，希望能夠給大家?guī)硪恍椭?，如果您需要了解更多相關(guān)內(nèi)容，可以給我們網(wǎng)站留言或來電進行咨詢。
