玻璃钢管以机械强度高、重量轻、耐腐蚀、使用寿命长、安装和维修费用低,以及综合经济效益好等优点正在替代金属钢管,并已广泛用于石油行业。 目前,美国、意大利、日本、德国等大量应用玻璃钢管,国内近几年也开始使用玻璃钢管,中国石油天然气集团公司十分重视玻璃钢管的推广工作,决定今后油田管道建设量的50％将使用玻璃钢管。国外玻璃钢管施工经验值得我们借鉴。 铺管施工时,管沟底要铺较厚的砂层或夯实细土层,然后按设计要求铺上垫层材料并夯实。每种玻璃钢管接头都有特殊的安装要求,直径大于152.4mm的管子要在沟内安装,小于152.4mm的管子可在沟上安装。在承插连接中,须在
Fiberglass pipes are being replaced by metal pipes due to their high mechanical strength, light weight, corrosion resistance, long service life, low installation and maintenance costs, and good overall economic efficiency. They are widely used in the petroleum industry. At present, the United States, Italy, Japan, Germany and other large-scale application of glass fiber reinforced plastic pipe, the domestic use of glass pipe in recent years, China National Petroleum Corporation attaches great importance to the promotion of glass pipe, decided that 50% of future oil pipeline construction will use fiberglass tube. Foreign glass pipe construction experience is worth our lesson. Pipelaying construction, the bottom of the trench to shop thicker sand or compacted fine soil, and then according to the design requirements laid mat material and compaction. Each type of FRP pipe fitting has special installation requirements. Pipe diameters greater than 152.4 mm are to be installed in the groove and pipes smaller than 152.4 mm can be installed in the groove. In the socket connection, to be in
