卷管現貨(huo)壁厚6-120mm

　　卷管致力于生產環縫、縱環各類卷管及鋼制壓力鋼管并在傳統卷管設(she)備(bei)同類規格型號的(de)(de)(de)基礎(chu)上進行改造。使卷管設(she)備(bei)的(de)(de)(de)各項參(can)數提高(gao)30%之功能，填補(bu)了原有傳(chuan)統卷制設(she)備(bei)不能生產的(de)(de)(de)空白(bai)。可生產直(zhi)徑400以上，壁厚8-100mm的(de)(de)(de)鋼管。

　　材質主要(yao)有(you)Q235A、Q345B、20 45# ,35cimo跟 42cimo,16錳(meng)、16錳(meng)容 ，一(yi)般冷軋板可以(yi)用以(yi)卷(juan)管 ，等。產品執行(xing)標準為：GB/T50205-2001、GB/T3092-2001等。

　　卷管廣泛用于石油、化工(gong)(gong)、天然氣(qi)(qi)輸(shu)送、打樁及(ji)城市供水(shui)、供熱、供氣(qi)(qi)等工(gong)(gong)程。

　　鋼板卷管是由普通碳素鋼板卷制連接而成適宜低溫低壓輸送的鋼管，由此叫做碳素鋼板卷管。鋼板卷管屬于(yu)有(you)縫(feng)管(guan)，與無(wu)縫(feng)鋼(gang)管(guan)相(xiang)比，由于(yu)材質(zhi)、焊縫(feng)的(de)(de)質(zhi)量(liang)保證問(wen)題，決定(ding)了無(wu)縫(feng)鋼(gang)管(guan)的(de)(de)質(zhi)量(liang)優于(yu)有(you)縫(feng)管(guan)。承(cheng)(cheng)壓設備(bei)的(de)(de)受壓元(yuan)件(jian)(jian)必(bi)須(xu)使(shi)用無(wu)縫(feng)鋼(gang)管(guan)。一(yi)般非承(cheng)(cheng)壓結構或結構件(jian)(jian)可以使(shi)用有(you)焊縫(feng)的(de)(de)卷管(guan)。

　　鋼板卷管的品(pin)種(zhong)標(biao)準日(ri)益增多，并(bing)在(zai)越(yue)來越(yue)多的范(fan)疇代替(ti)了(le)(le)無縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)(guan)。鋼(gang)(gang)板(ban)(ban)卷(juan)(juan)(juan)管(guan)(guan)(guan)(guan)按焊縫(feng)(feng)的辦(ban)法(fa)分為直縫(feng)(feng)鋼(gang)(gang)板(ban)(ban)卷(juan)(juan)(juan)管(guan)(guan)(guan)(guan)和螺旋鋼(gang)(gang)板(ban)(ban)卷(juan)(juan)(juan)管(guan)(guan)(guan)(guan)。鋼(gang)(gang)板(ban)(ban)卷(juan)(juan)(juan)管(guan)(guan)(guan)(guan)是由(you)普通碳(tan)素(su)(su)鋼(gang)(gang)板(ban)(ban)一(yi)段(duan)一(yi)段(duan)卷(juan)(juan)(juan)制連接而成適宜低(di)溫低(di)壓(ya)(ya)介子輸(shu)送的鋼(gang)(gang)管(guan)(guan)(guan)(guan)，由(you)此叫做碳(tan)素(su)(su)鋼(gang)(gang)板(ban)(ban)卷(juan)(juan)(juan)管(guan)(guan)(guan)(guan)。鋼(gang)(gang)板(ban)(ban)卷(juan)(juan)(juan)管(guan)(guan)(guan)(guan)屬于有(you)縫(feng)(feng)管(guan)(guan)(guan)(guan)，與無縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)(guan)相比，由(you)于材質(zhi)(zhi)、焊縫(feng)(feng)的質(zhi)(zhi)量保證問(wen)題(ti)，決定(ding)了(le)(le)無縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)(guan)的質(zhi)(zhi)量優(you)于有(you)縫(feng)(feng)管(guan)(guan)(guan)(guan)。承壓(ya)(ya)設備的受壓(ya)(ya)元件必須使用(yong)無縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)(guan)(guan)。一(yi)般非承壓(ya)(ya)結構或結構件可(ke)以使用(yong)鋼(gang)(gang)板(ban)(ban)卷(juan)(juan)(juan)管(guan)(guan)(guan)(guan)的有(you)縫(feng)(feng)管(guan)(guan)(guan)(guan)。

　　鋼板卷管(guan)主要應用(yong)于(yu)自來水工程(cheng)、石(shi)化工業、化學工業、電力工業、農業灌(guan)溉(gai)、城市建(jian)(jian)設。作(zuo)液體輸送用(yong)：給(gei)水、排水。作(zuo)結構用(yong)：作(zuo)打樁(zhuang)管(guan)、作(zuo)橋(qiao)梁;碼(ma)頭、道路、建(jian)(jian)筑結構。
