蒸汽干燥机盘管的工艺制作探讨分析

Discussion and Analysis of the Process Making of the Coil in the Steam Dryer

介绍蒸汽干燥机盘管的技术参数及制作过程,主要包括原料的检验,主管及支管的制作与组装,最后整体架构及焊缝的检验。盘管的主管和支管分别采用双相不锈钢S31603和S32205,采用冷拔推制的办法在主管上加工出一定高度的凸台,将弯制好的支管点焊固定在主管上,两边对称地焊接起来。特别对蒸汽干燥机盘管的焊接工艺作了详细的论述。

The paper describes the technical parameters and production process of the coil of a steam dryer, mainly including theinspection of raw materials,production and assembly of directors and branches, the inspection of the final overall architecture and theweld joints. Duplex stainless steel S31603 and S32205 are separately used for the directors and the branches of the coil. The method ofcold drawing and pushing is used to process some convex platforms with a certain height on the directors. After that, the bent branchesare fixed on the directors by welding both sides symmetrically. In particular, the welding process of the coil of the steam dryer isdiscussed in detail.
