Dwyer系列a-1000優(yōu)質(zhì)管件經(jīng)過設計和制造,可在多種應用場合提供可靠的無泄漏連接。 一個可靠的無泄漏油管系統(tǒng)將通過正確選擇和處理油管與正確的管件選擇和安裝相結(jié)合來實現(xiàn)。 提供以下信息,以協(xié)助管的選擇。
材料 所選擇的油管材料必須與系統(tǒng)所包含的介質(zhì)、壓力和溫度以及安裝環(huán)境相一致。
同樣,管道和配件的材料應該相似,以達到的密封效果(不銹鋼管的不銹鋼配件,銅管的黃銅配件,碳鋼管的碳鋼配件,等等)。 不同材料的混合和接觸可能使系統(tǒng)易受電偶腐蝕和/或不允許實現(xiàn)適當?shù)墓芗M裝。
壓力和流量
管道外徑的尺寸(外徑)和必要的壁厚由系統(tǒng)的壓力和流量要求決定。 表A(見目錄頁)詳細說明了與儀表管連接件一起使用的建議的管徑和壁厚。 如果在表上沒有顯示特定尺寸的壓力,則不建議與儀表管配件一起使用管道。 管道系統(tǒng)的使用不應超過管道的允許工作壓力。
溫度
系統(tǒng)的工作溫度可能影響管道材料的最初選擇,也可能影響給定管道尺寸的允許工作溫度(有關溫度應力因素,請參閱目錄頁的表B)。
為了成功地連接輕燃氣管道,管道必須有足夠厚的管壁,以提供足夠大的阻力,防止套圈的安裝動作進一步補償管道的潛在表面條件。
油管上的表面劃痕和鑿痕是潛在泄漏的來源。在操作管道時,一些預防措施可以幫助減少表面劃痕,并保持表面光潔度符合制造商最初的要求。
油管不應該被拖過巖石,柏油路,路面,或油管存儲架作為劃痕和鑿可能發(fā)生。 鋒利的刀片會導致內(nèi)外懸掛毛刺,導致油管變成橢圓形,影響管件內(nèi)的正確插入。 作為一種良好的操作實踐,在安裝管件之前,油管應該總是去毛刺,以幫助確保容易和完整的管插入。 此外,對于彎管總成,重要的是在安裝管配件之前彎管,并在彎管之后提供足夠的直長度,使管能夠插入到配件中。 此外,為了消除管件上油管的重量應力,并提供額外的系統(tǒng)支持,以抵抗振動和熱沖擊,油管應該始終由管架、夾鉗或托盤支撐。
