Product Information :

Api 5L X52 X60 X70 Monoblock Insulating Joint. It is the type of fixing the insulating board and insulating sealing filler into the assembly unit. After completion of assembling of the mdd1.25-187(5) male pre-insulating joint, the internal components shall be fixed at the relevant positions. The whole mdd1.25-187(5) male pre-insulating joint is in good condition under soil pressure, specified pipeline operating pressure and factory or field hydraulic test pressure. The sealing component contacts with the insulating board tightly inside the mdd1.25-187(5) male pre-insulating joint and has everlasting elasticity. In addition, both sides of the sealing component contact directly with the naked surface of metal without moving, which ensure the compactness of the mdd1.25-187(5) male pre-insulating joint.
