Fire protected pipe and pipeline

摘要: An oil carrying pipe for an rig riser comprises anti-corrosion covering (2), a fire protection (3) over the (2) and outer coating (4) to retain cover in place. A field joint (5) comprising three protective coverings (2, 3 4), is applied at base ends of two connected pipes (1). The retaining matrix modified ethylene acrylic polymer having dispersion metal containing compounds, such as aluminium trihydrate zinc borate. Under normal conditions will protect against impact, abrasion like. Even though material char on exposure fire, compounds fuse form continuous stable which position long enough prevent immediate blow out thereby allow time evacuate larger area.
