2PE-3PE鋼管是國內(nei)常用的管道(dao)之一(yi)(yi)，是指2層(ceng)(ceng)結(jie)構(gou)聚(ju)(ju)烯烴涂層(ceng)(ceng)外鋼管。2PE-3PE鋼管一(yi)(yi)般是由三層(ceng)(ceng)結(jie)構(gou)組成，層(ceng)(ceng)環氧(yang)粉末，層(ceng)(ceng)膠(jiao)粘劑，第三層(ceng)(ceng)聚(ju)(ju)乙烯在實際操作中將三種(zhong)材料(liao)混合融為一(yi)(yi)體，經過加工使之與鋼管牢(lao)固結(jie)合形(xing)成優良的層(ceng)(ceng)。其加工方式(shi)一(yi)(yi)般分纏繞式(shi)和圓模包(bao)覆式(shi)兩(liang)種(zhong)。

2PE-3PE鋼管根據(ju)標準準主要規(gui)范(fan)聚乙(yi)(yi)烯(xi)(xi)與聚乙(yi)(yi)烯(xi)(xi)為(wei)主，維(wei)卡軟化(hua)點定(ding)(ding)為(wei)不(bu)小(xiao)于110℃；外層的(de)厚度(du)(du)按以低、中密(mi)度(du)(du)聚乙(yi)(yi)烯(xi)(xi)為(wei)主的(de)德國標準來確定(ding)(ding)。   大(da)地提高了2PE層的(de)抗沖擊強度(du)(du)。將3PE層的(de)剝(bo)離強度(du)(du)、抗沖擊的(de)指標大(da)幅提高，并明確規(gui)定(ding)(ding)了據(ju)一些料炭黑含量，了3PE層的(de)機械強度(du)(du)和(he)耐候(hou)性能，并加大(da)了補口剝(bo)離強度(du)(du)(即熱縮套、熱縮帶(dai)的(de)對底(di)漆(qi)鋼的(de)剝(bo)離強度(du)(du))抽測頻次。

2PE-3PE鋼管(guan)(guan)(guan)(guan)(guan)(guan)其(qi)適用(yong)于煤礦井下供(gong)排水(shui)(shui)、井下噴(pen)漿、正(zheng)負(fu)壓通風、抽放(fang)瓦斯、消防(fang)灑(sa)水(shui)(shui)等管(guan)(guan)(guan)(guan)(guan)(guan)網。熱(re)(re)電廠工藝用(yong)水(shui)(shui)廢渣、回水(shui)(shui)輸(shu)送(song)(song)管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)。對于防(fang)噴(pen)淋、灑(sa)水(shui)(shui)系(xi)統的(de)(de)給水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)路(lu)具有的(de)(de)適用(yong)性(xing)。電力、通訊、高(gao)速公路(lu)等電纜(lan)保護套管(guan)(guan)(guan)(guan)(guan)(guan)。適用(yong)高(gao)層建筑給水(shui)(shui)、熱(re)(re)網供(gong)熱(re)(re)、自來(lai)水(shui)(shui)工程(cheng)、燃氣輸(shu)送(song)(song)、埋(mai)地輸(shu)水(shui)(shui)等管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)。石油(you)輸(shu)送(song)(song)管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)、化工制藥、印染等行業輸(shu)送(song)(song)腐蝕性(xing)介(jie)質的(de)(de)工藝管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)(dao)。污水(shui)(shui)處(chu)理(li)排放(fang)管(guan)(guan)(guan)(guan)(guan)(guan)、污水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)以及生物池(chi)工程(cheng)。農(nong)業灌溉用(yong)管(guan)(guan)(guan)(guan)(guan)(guan)、深井管(guan)(guan)(guan)(guan)(guan)(guan)、排水(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)等網路(lu)等等用(yong)途，可以說2PE-3PE鋼管(guan)(guan)(guan)(guan)(guan)(guan)在(zai)當前的(de)(de)建設(she)中(zhong)是的(de)(de)，而(er)相信通過科技(ji)的(de)(de)延伸，未來(lai)其(qi)還(huan)是有加(jia)輝煌(huang)的(de)(de)成績(ji)。
