產(chǎn)品詳情
H型鋼是斷面形狀類似于大寫拉丁字母H的一種經(jīng)濟(jì)斷面型材,又叫鋼梁、寬邊(緣)工字鋼或平行邊(翼緣)工字鋼,其不同于國內(nèi)沿用已久的翼緣較窄且內(nèi)側(cè)面傾斜的熱軋工字鋼。H型鋼的斷面形狀與普通工字鋼的的區(qū)別見圖。H型鋼的斷面通常分成為腰部和邊部,又稱為腹板和翼緣。H型鋼的邊部內(nèi)側(cè)與外側(cè)平行或接近于平行,邊端部呈直角,由此得名平行邊工字鋼。與腰部同樣高度的普通工字鋼相比,H型鋼的腰部厚度小,邊部寬度大,因此又叫寬邊工字鋼。

中心夾雜物電鏡掃描發(fā)現(xiàn),裂紋源中心存在夾雜物,夾雜物主要為鋁酸鈣類型,是在煉鋼脫氧過程中產(chǎn)生。線材中非金屬夾雜物的存在,破壞了組織和基體的連續(xù)性,夾雜物的存在起到了一個(gè)顯微裂紋的作用,一旦受力,當(dāng)裂紋達(dá)到失穩(wěn)狀態(tài)尺寸,便瞬間產(chǎn)生斷裂,形成斷絲。異常組織斷絲中心會存在粗細(xì)不均、斷續(xù)分布的一條或多條白條帶組織,并有垂直拉伸方向的短細(xì)裂紋存在。分析發(fā)現(xiàn)為Mn、Cr等合金元素的偏析。偏析的存在,線材在正常冷卻速度下使C曲線右移,在中心產(chǎn)生條帶狀馬氏體異常組織。

HDPE管的滲透率遠(yuǎn)低于水泥管材,低于2%,對地下水不會造成二次污染;水泥管材無彈性,雖然配有膠圈,但密封效果差,特別是施工人員由于水泥管材重,不好施工,索性不管承插的效果,導(dǎo)致膠圈失去作用,從而使管材滲透率提高。HDPE管使用壽命長,5年以上。PE管的安全使期為5年以上,這一點(diǎn)不僅已為標(biāo)準(zhǔn)和新所證明,而且已被先進(jìn)證明。水泥管理論上使用壽命2年,但是其為硅酸鹽類,長期受到酸堿的腐蝕,壽命大大降低。
