摘要
导管架立管预制与安装对于尺寸要求非常严格,由亍立管外表面通常带有防腐涂层(3层PP、3层PE或者氯丁橡胶),加之管径一般较大,使得立管中的8。(不全是8。)弯管和90。弯管两端的直管段很难进行准确测量。提出了一种新的测量方法,即通过间接测量来准确测定立管中的弯管两端的直管段长度,并在荔湾3.1导管架5根立管的预制过程中得到很好的应用。
There is strict request for size in prefabrication and installation of jacket riser. Usually, the riser is externally coated with 3 layers of PP or PE or neoprene. Besides, diameter of the riser is large. All these make it difficult to measure the straight length between an 8 degree bend and a 90 degree one on the riser exactly. This paper provides a new method which can solve the problem mentioned above. This new method has been used in prefabrication and installation of riser in LW3-1 jacket project.
