1.Anti Corrision Stainless Steel Tube With Hot Rolled Sgs Certificate
we are widely used in the streets and at the seaside, where require higher corrosion resistant material. We have a professional design team and we can design and customize the light poles for your projects. With the basic of integrated light pole solution, we widely establish corporation with lots of well-known enterprises of LED lamps and power, etc. We supply one-stop solution to simplify the customers′ procurement of lighting products.
ERW | SAW | SML | |
Actual weld- throat length | SAW IS 4-5 times than ERW, | ||
Overlap | can be cleared , reduce the temperature rise caused by friction | in long length can't be cleared | |
Internal stress | small, good for pipes | complex, Not good for Cracking and stress corrosion of inner wall defects | |
Size | short weld-throat length , thickness is uniform ,geometric dimensions have good precision , good anti-corrosion , easy to install | long weld-throat length, finished pipes have weld-throat and anti-corrosion treatment problems | common geometric dimensions,common precision |
pipe material | better pure steel | steel with more C |
