pipe


Inner flat mirror face of stainless steel weld pipe is famous for precise size、property、surface sanitation and high precision. Precision of our liquid steel pipe reach to the excellent level which outer diameter、 inner diameter and thickness is ±005mm when we cooperated with dairy product、beer、pharmacy、juice and food industry etc. Therefore, we have established fellowship due to our stable quality.
Inner flat mirror face of stainless steel weld pipe is widely used in food、dairy product、drink、brewage、pharmacy and biology project etc. Its customer group are vast. Good user basis have been set up.
The used materials cover: 304、304L、316、316Letc.
Specifications: outer diameterφ19.1-φ1148.3mm,wall thickness0.6-3.0mm.
