1, construction should avoid the immersion of groundwater and rainwater, if the end accidentally soaked in water, should do dry treatment before connecting the jacket.
2, pipes should be stored in a flat site, neatly stacked, stacking height should be less than 1.5 meters.
3, pipe hoisting in light, no collision, throwing, prohibit wire rope straight hanging pipe body.
4. Thermal insulation layer and anti-corrosion layer should avoid direct contact with flame. For on-site installation, please follow the following procedures: pipe trench excavation-base treatment (drainage, sand padding)-pipe laying-steel pipe welding-inspection (water pressure)-installation (pressure test)-foaming-sealing foam holes. For the installation of elbow and joint, personnel can be sent to the project site to carry out the insulation work of the joint, including the installation of the joint outer sleeve, the connection and sealing between the joint outer sleeve and the main pipe, and the foaming work of the joint, but does not include the welding work of the joint part of the steel pipe.
