Description:
About high precision galvanized pipe, "ShengDingYuan" can meet the technical requirements, using environmental protection galvanized + 6 Gr, the thickness of the galvanized layer according to the requirements of the guests (6 um - 12 um), such as salt spray testing can be carried out in accordance with the requirements of the guests.
Surface effect: after galvanized,the surface is much brighter than NBK tube, surface colour distributed and very beautiful.After galvanizing on precision seamless tube,different levels of bending and deformation can be made without zinc dropping.
The Galvanized surface rust is used in the working conditions of the environment, such as the sea, the outdoor environment for a long time.
Applications:
Automotive,military,railway industry,with high requirement of the tube’s brightness, cleanness,antirust,and antisepsis.
