Galvanized pipe

Galvanized pipe: 1.Shape:Conoid ,Multi-pyramidal,Columniform,polygonal or conical 2.Material:steel plate.stainless steel compound plate,stainless steel plate,ect.(anticorrosion treatment with hot galvanization,also color polyester power could be coated on the surface) High strength low alloy steel Q235,Q345 to ensure the mechanical properity of microelement in order to ensure the quality of galvanization (other materials are also avaliable on requesr) 3.Jointing of pole with insert mode,innerflange mode,face to face joint mode . 4.Design of pole :against earthquake of 8 grade ,aganist wind pressure of 160 5.Minimum yield strength:355 6.Minimum ultimate tensile strength :490 7.Max ultimate tensilestrength:620355 8.Certificate:ISO9001-2000 9.Length:Within 14m once forming without slip joint 10.Welding:It has past flaw testing.Internal and external double welding makes the welding beautiful in shape Our power transmission equipment are made from quality sheet from bending,forming,automatic welding and hot galvanization.We can reach one-run machining length of 14m,and can bend sheet thickness up to 25mm.We adopt advanced welding procedures ,automatically weld main joints and reach rank-II welding quality.
