1.0产品和重大PROCESSES:
1.1产品在这个档案勾勒出是目前由标题即认可。部门手册钢管,BUIZEN与配件然而其特别实用程序识别喜欢用于输送水, 加油站,空气蒸汽等。,for use in basic purposes,for General Engineering purposes and so on。Funnels of different materials(bijvoorbeeld,铸铁,PVC,HDPE,水泥混凝土等。)或具有不同的效用像氧叉甚至一些其他槽钢,电气布线框架等的保险利用当然管一直保持这个手册的结构域的出。
1.2有关此共同管理他们的装配标准项目的理解形成伴随说明注(参考文献1.3 1.5 AAN下)和措辞(Ref. 2.0)认为includi下描绘在各种规范ng those characterized at IS1956年(铂。八) - 1976(术语词汇与钢铁识别:钢管)and IS812 - 1957年(Glossary of terms identifying with Welding and Cutting of Metals)as well as Metals Hand Books distributed by American Society for Metals would demonstrate helpful。
1.3接钢管PROCESSES
在此过程中纵向成帧室(说板外,skelp,level,strip,板等。)通过像形成在纵向折痕被接合: -
A)ELEKTRISCHE weerstandslassen(ERW) -它利用业务的发展,in the first the level moved steel is chilly molded into tubular shape。Welding is affected by the use of weight and warmth produced by enlistment or by an electric flow through the crease。焊接重量通过紧固辊和高焊接电流的电磁影响创建。电保护焊接具有纵向折痕的管状物品的通常的尺寸制成3.2毫米托特
0.6m genuine outside distance across,然而更大的尺寸额外产生。
B)Furnace Butt Welding-In heater butt welding,制管钢板具有正方形或侮辱性倾斜边缘是加热器加热到焊接温度。The warmedvoorraad被辊成帧为圆和空心形状,因为它上升塑造加热器,额外的温暖通常由氧气或空气飞给定撞击折痕边缘和管经过订约辊,其中折痕边,通过轧辊的重量被焊接。加热器对焊的产品在普通直径接近3.2毫米托特100 mm.
C)熔焊-In this procedure the level moved steels with edges reasonably arranged,is framed into tubular shape either by hot or cool forming。水平移动的钢可能会形成纵向(直线折痕)或扭曲成螺旋状的纵向(winding welded)。德randen zijn
met of zonder al die tijd houden vuller metaal in een vloeibaar of vloeibare en-damp-staat gelast. Mechanische gewicht isn ’ t vereist om de impact van lassen. Combinatie mogelijk deskundige door elektrische circulaire segment of gas opwarming van de aarde of door een mix van beide.
1.4NAADLOZE STALEN比伊斯处理
1.4 NAADLOZE STALEN PROCES
Stalen chroombuizen items geleverd via consistente procedures worden gemaakt in de afstanden over voor het grootste deel t/m 0.66 m door de draaiende doordringende techniek en tot 1.22 m door hete uitwijzing.
一个)Rotary Piercing-In revolving penetrating,重要的宽度和长度的轮首先升温至移动温度。每个热轮被维持成具有交叉战斧和表面形式的力它通过移动辊的布置,along these lines bursting it longitudinally。The power of the moves at that point makes the metal stream around a penetrating point,放大的枢转开口,smoothing within surface and framing a tube。Subsequent to being penetrated,不愉快的管通常被热移动到确凿测量。
B)Press Piercing-A press puncturing plant is made out of three essential components:一招仍与一对夫妇从动辊之间的轮去;钢坯推;and a settled fitting situated between the two rolls。钢坯,包含在四侧管理,一个通过推动器的加入活动和所确定的轧辊约束靠在安装。该材料在扭曲压缩基本上在此过程中先天,低延长(1.2%greatest)因此坯料材料(老式的或不断投)不经受高弹性焦虑。In the wake of being punctured,the harsh tube is hot moved to definite measurement。
C)热挤压是使凹陷热工序,适当处理成一致的和不可预测的帧的管的处理完成,通过迫使热,prepierced billets through a reasonably molded hole shaped by an outer bite the dust and interior mandrel。
