钢管塔制作工艺流程

钢管塔制作工艺流程主要包括以下步骤：

?放样与号料?：根据设计图纸进行放样，生成零件加工图纸和材料清单。

?切割与成型?：使用相贯线切割机或火焰切割机切割钢管，并进行冷弯或热弯成型。

?焊接?：采用手工电弧焊或CO?气体保护焊进行焊接，焊缝需进行外观检查。大管径钢管焊接需注意坡口形式和焊后处理。

?防腐处理?：对焊接完成的钢管塔进行热镀锌处理，镀锌厚度通常≥86μm以提高耐腐蚀性。

?组装与检验?：将预制构件组装成完整铁塔，并进行质量检查，确保符合设计要求。

?包装与运输?：检验合格后进行包装，通过**物流运输至现场安装。

The production process of steel pipe tower mainly includes the following steps:

Layout and marking: Based on the design drawings, layout is carried out to generate part processing drawings and material lists.

Cutting and Forming: Use a intersecting line cutting machine or flame cutting machine to cut steel pipes and perform cold bending or hot bending forming.

Welding: Manual arc welding or CO ? gas shielded welding is used for welding, and the weld seam needs to undergo visual inspection. Attention should be paid to the groove form and post weld treatment when welding large diameter steel pipes.

Anti corrosion treatment: Hot dip galvanizing treatment is carried out on the welded steel pipe tower, with a galvanizing thickness usually ≥ 86 μ m to improve corrosion resistance.

Assembly and Inspection: Assemble prefabricated components into a complete iron tower and conduct quality inspections to ensure compliance with design requirements.

Packaging and transportation: After passing the inspection, packaging is carried out and transported to the site for installation through professional logistics.
