方管工艺分类有哪几种?

发布时间:2021-09-09 来源:http://www.jnhxtcg.com -> 浏览量:

建筑施工过程中,我们会看到很多不同的建筑钢材,它们所起到的作用也是不一样的,其中包含了方管。很多朋友只知道方管是建筑钢材,但对于它的工艺分类了解的并不是太多,接下来就让我们跟随济南方管的小编来为您讲一讲:

During the construction process, we will see many different building steels, which play different roles, including square tubes. Many friends only know that square tube is construction steel, but they don't know much about its process classification. Next, let's follow the Xiaobian of Jinan square tube to tell you:

方管工艺分类介绍

Introduction to process classification of square tube

方管按生产工艺分:热轧无缝方管、冷拔无缝方管、挤压无缝方管、焊接方管。

Square tubes are divided into hot-rolled seamless square tubes, cold drawn seamless square tubes, extruded seamless square tubes and welded square tubes according to the production process.

其中焊接方管又分为:

The welded square pipe is divided into:

1、按工艺分——电弧焊方管、电阻焊方管(高频、低频)、气焊方管、炉焊方

1. According to the process - arc welding square tube, resistance welding square tube (high frequency and low frequency), gas welding square tube and furnace welding square tube

2、按焊缝分——直缝焊方管、螺旋焊方管。

2. According to the weld - straight welded square pipe and spiral welded square pipe.

材质分类:

Material classification:

方管按材质分:普碳钢方管、低合金方管。

Square tubes are divided into ordinary carbon steel square tubes and low alloy square tubes according to material.

1、普碳钢分为:Q195、Q215、Q235、SS400、20#钢、45#钢等。

1. Ordinary carbon steel is divided into Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc.

2、低合金钢分为:Q345、16Mn、Q390、ST52-3等。

2. Low alloy steels are divided into Q345, 16Mn, Q390, St52-3, etc.

生产标准分类:

Square pipes are classified according to section shape:

1、简单断面方管:方形方管、矩形方管。

1. Simple section square tube: square tube, rectangular square tube.

2、复杂断面方管:花形方管、开口形方管、波纹形方管、异型方管。

2. Square tube with complex section: flower shaped square tube, open square tube, corrugated square tube and special-shaped square tube.

表面处理分类:

Surface treatment classification:

方管按表面处理分:热镀锌方管、电镀锌方管、涂油方管、酸洗方管。

Square pipes are divided into hot-dip galvanized square pipes, electro galvanized square pipes, oiled square pipes and pickled square pipes according to surface treatment.
