Neutral gas subsea transportation
Project Name: Neutral gas subsea transportation
Product involved: Seamless pipe with concrete external coating & epoxy internal coating
Specification: API5L X52 PSL1 610 x 18 mm
Quantity: 2610 Metric Tons
Project location: Nacala/mozambique
Year:2016
Country:Nacala/mozambique
Application:Offshore marine
Project Introduction
This project was designed for Neutral gas transportation under sea. Because of the high working pressure and considering the life cycle of material, steel grade of X52 was used, and concrete coating for external coating, Epoxy coating for internal side applicated.
Project Difficulties
To enhance the adhesive property between concrete and pipe surface, in one hand, we have to assure the surface roughness; To solve this difficulty,we do additonal surface treatment after normal pipe production procedure.
