style="text-indent:25px">鍍鋅圓管的焊接過程控制：鍍鋅圓管焊接前的準備與低碳鋼相同。應注意槽的尺寸和附近的鍍鋅層應小心處理。為了滲透，槽的尺寸應適當，一般60-65度，留有一定的間隙，昆明熱浸鍍鋅圓管廠家直銷，一般1.5-2.5mm。為了減少鋅對焊縫的滲透，在焊接前，可將槽內的鍍鋅層去除，然后焊接。在實際監(jiān)理工作中，采用集中開槽、無鈍邊技術和雙層焊接技術對集中開槽進行控制，降低了不穿透的可能性。焊條應根據(jù)鍍鋅管的基材選用。J422由于操作簡單，是低碳鋼的常用選擇。焊接方式:多層焊縫第壹層焊接時，昆明熱浸鍍鋅圓管廠家直銷，盡量使鋅層在焊縫外熔化汽化蒸發(fā)，可很大程度上減少焊縫中殘留的液態(tài)鋅。當角焊縫焊接時，鋅層在第壹層熔化，蒸發(fā)蒸發(fā)，昆明熱浸鍍鋅圓管廠家直銷，從焊縫中逸出。方法是將電極頭向前移動5-7mm左右，待鋅層融化回到原來位置后繼續(xù)焊接。短渣電極如J427用于交叉焊和立焊時，咬邊傾向很小;采用前后輸送桿技術，可獲得無缺陷焊接質量。昆明鍍鋅圓管批發(fā)，云南鍍鋅圓管報價表，昆明鋼好物資供應。昆明熱浸鍍鋅圓管廠家直銷</p><div

style="text-indent:25px">鍍鋅鋼管的鋅鍍層的使用溫度不得超過2500C,在此溫度上鋅結晶組織變形，發(fā)脆，耐蝕性下降。有耐蝕，耐熱要求的零件宜用Zn-Ni合金層。鍍鋅電解液可分為堿性和弱酸性兩大類，國內外常用的有無氰鋅酸鹽鍍鋅，氰鍍鋅，銨鹽鍍鋅，硫酸鹽鍍鋅等。就國內而言，無氰鋅酸鹽鍍鋅仍是主流。近年來由于鍍鋅添加劑的性能的改進提高，氯化物鍍鋅和低氰光亮鍍鋅發(fā)展較快，而銨鹽鍍鋅在繼續(xù)下降。選擇鍍液要根據(jù)鍍件材質，形狀，外觀要求而定，如沖壓小件和復雜件，特別是需要輔**極的深孔或管狀件宜選用堿性鍍液﹔對氫脆敏感的零件宜用弱酸性鍍鋅液。當采用兩種性能不同的鍍液時，對鍍鋅鋼管生產十分有利。昆明熱浸鍍鋅圓管廠家直銷目前消防給水管道基本上是鍍鋅管，鍍鋅管外層涂有油漆，其實它們只是經過鍍鋅圓管加工而成。</p><div
