昆明{管路减震}BGF-DN200波纹膨胀节

作者:admin   时间:2018-11-22 14:59   

    名称:不锈钢金属补偿器  口径:DN300mm  压力:PN16  波数:6波
 
    Name: stainless steel metal compensator caliber: DN300mm pressure: PN16 wavenumber: 6 wave。
 
    波纹膨胀节是由哪些部分组成的
 
    波纹膨胀节的工艺是怎样的,由于膨胀节的结构不同,生产工艺也不相同,主要工序有:导向块或挡板等附件)—压力试验—其他附件的装配或焊接(如内导流套、外套、导向杆、预拉伸杆等)—总装检验。







    波纹管和端管的连接焊缝往往属于异种钢焊接,不锈钢中的合金元素含量经焊接后会有烧损和稀释。为防止腐蚀的发生,该焊缝的焊接需要采用特别的焊接材料并应进行100%无损检验,不允许存在任何缺陷。为保证波纹管元件和端管连接处的焊接强度,波纹管元件和端管的焊接不采用搭接形式而采用对接的形式,以确保该连接焊缝承受的是正应力而非剪应力。
 
    What is the process of bellows expansion joint? Because of the different structure of expansion joint, the production process is also different. The main procedures are: guide block or baffle accessories) - pressure test - assembly or welding of other accessories (such as inner diversion jacket, jacket, guide rod, pre-stretching bar, etc) - assembly inspection.
 
    The welding seam between corrugated pipe and end pipe often belongs to dissimilar steel welding. The alloy element content in stainless steel will be burned and diluted after welding. In order to prevent corrosion, special welding materials should be used and 100% nondestructive testing should be carried out. No defects are allowed. In order to ensure the weld strength of the joint between bellows and end tubes, the joint of bellows and end tubes is butted instead of overlapping, so as to ensure that the joint seam bears normal stress rather than shear stress.



 
    材料说明:淞江集团所有波纹补偿器产品所有波纹全部采用不锈钢304正材生产,支持各种光谱仪检测,假*赔十,厚度全部厚于同行业标准,为了更持久的使用寿命,法兰全部采用山西正宗锻打材质,焊材全部采高于母材等*标准,耳板全部采用加大加厚尺寸生产,螺杆全部采用8.8*高强度镀锌,为*确保产品的综合强度,淞江集团通过.压力管道生产许可要求,TS编号:TS2731B90-2020,并且严格按照TS压力管道生产要求进行生产,让出厂的每*个波纹补偿器产品达到合格淞江集团工程案例
 
    Material Description: All ripple compensator products of Songjiang Group are made of 304 stainless steel, supporting various spectrometer detection, false compensation 10, thickness all thicker than the same industry standard。 In order to have a longer service life, all flanges are made of Shanxi authentic forging materials, all welding materials are higher than the standard of base metal。 In order to ensure the comprehensive strength of the products, Songjiang Group passed the production licensing requirements for pressure pipes, TS number: TS2731B90-2020, and strictly according to the production requirements of TS pressure pipes, each of the corrugated compensators produced by the factory was released。 The product is qualified。
