⑶保溫制品的拼縫寬度,一般(ban)不(bu)得大于5mm,且施工時需(xu)注意錯縫。保溫鉤(gou)釘(ding)銷釘(ding)的安裝，一般(ban)設(she)備出廠(chang)前(qian)都(dou)已把保溫鉤(gou)釘(ding)和(he)支(zhi)承件焊(han)接在設(she)備上，到(dao)現(xian)場只要安裝保溫層(ceng)和(he)保護(hu)層(ceng)就可以(yi)了。出廠(chang)前(qian)沒有焊(han)好鉤(gou)釘(ding)需(xu)現(xian)場焊(han)接的，單(dan)位面積上鉤(gou)釘(ding)或銷釘(ding)數，側部不(bu)應少于6個/m2

，底部不(bu)應(ying)少于(yu)(yu)8個/m2。焊接(jie)鉤釘或(huo)銷釘時，應(ying)先用(yong)粉(fen)線(xian)在(zai)設備(bei)、管(guan)道壁上(shang)錯行或(huo)對行劃出每個鉤釘或(huo)銷釘的(de)(de)位置(zhi)。支(zhi)(zhi)承(cheng)(cheng)(cheng)件(jian)(jian)(jian)的(de)(de)安裝，對于(yu)(yu)支(zhi)(zhi)承(cheng)(cheng)(cheng)件(jian)(jian)(jian)的(de)(de)材(cai)質(zhi)，應(ying)根(gen)據(ju)設備(bei)或(huo)管(guan)道材(cai)質(zhi)確定(ding)，宜(yi)采(cai)用(yong)普通碳鋼板(ban)或(huo)型鋼制作。支(zhi)(zhi)承(cheng)(cheng)(cheng)件(jian)(jian)(jian)不(bu)得設在(zai)有附件(jian)(jian)(jian)的(de)(de)位置(zhi)上(shang)，環面應(ying)水(shui)平設置(zhi)，各托架(jia)筋(jin)板(ban)之間(jian)安裝誤(wu)差應(ying)大(da)(da)于(yu)(yu)10mm，當不(bu)允(yun)許直(zhi)(zhi)接(jie)焊于(yu)(yu)設備(bei)上(shang)時，應(ying)采(cai)用(yong)抱箍型支(zhi)(zhi)承(cheng)(cheng)(cheng)件(jian)(jian)(jian)，支(zhi)(zhi)承(cheng)(cheng)(cheng)件(jian)(jian)(jian)制作的(de)(de)寬(kuan)度應(ying)小于(yu)(yu)保溫層(ceng)厚度10mm，但不(bu)得大(da)(da)于(yu)(yu)20mm，立式設備(bei)和公稱直(zhi)(zhi)徑大(da)(da)于(yu)(yu)100mm的(de)(de)垂(chui)直(zhi)(zhi)管(guan)道支(zhi)(zhi)承(cheng)(cheng)(cheng)件(jian)(jian)(jian)的(de)(de)安裝間(jian)距，應(ying)視保溫材(cai)料松散程(cheng)度而定(ding)。
