異徑管reducer又稱(chēng)大小頭、異徑管、異徑直通。化工管件之一，用于兩種不同管徑的管道之間的銜接。大小頭焊后硬化性較大，容易發(fā)生裂紋。大小頭出產(chǎn)工藝簡(jiǎn)單，出產(chǎn)效率高，成本低，發(fā)展較快。大小頭出產(chǎn)的首要原材料在大小頭出產(chǎn)成本中占有很大比例，其價(jià)格的改變直接影響大小頭出產(chǎn)成本的改變。若選用同類(lèi)型的不銹鋼沖壓彎頭焊接，有必要進(jìn)行300℃以上的預(yù)熱和焊后700℃左右的緩冷處理。若焊件不能進(jìn)行焊后熱處理，則應(yīng)選用大小頭焊條。跟著世界經(jīng)濟(jì)的不斷發(fā)展，收入水平的不斷提高，我們方針面向世界先進(jìn)的建筑業(yè)及船舶業(yè)等相關(guān)行業(yè)。大小頭以銜接收件為主，在這一產(chǎn)品的發(fā)展范疇能夠擔(dān)任重?fù)?dān)，具備世界前列技術(shù)水平而啟航。
