產(chǎn)品詳情
彎頭是用于管道轉(zhuǎn)彎處的一種管件.在管道系統(tǒng)中所使用的全部管件中,所占比例較大,約為80%.通常,對(duì)不同材料和壁厚的彎頭選擇不同的成形工藝. 它的連接形式就是直接將彎頭與鋼管對(duì)焊
彎頭按度數(shù)分可分為45度.90度,180度;
按彎曲半徑分為長(zhǎng)半徑(R=1.5D)和短半徑(R=1D),其中長(zhǎng)半徑還有異徑彎頭.另外,根據(jù)配管走向的需要,還會(huì)有特殊角度的彎頭,如30度,60度,88度,25度等
按材質(zhì)來(lái)分可有:碳鋼,不銹鋼(304,304L,316,316L,321),合金鋼（12Cr1MoV,Cr5Mo,10CrMo910,15CrMo）.
