How to make the pipe fittings more resistant

  When a piping project un working, the steel pipes and pipe fittings are always facng the wear resistant problem ,especially when some impurity, sands,slurry in the flowing liquid .  Some technical measures should be arranged to reduce wear and tear about pipe and fittings .

  1.When we choose the steel material of the pipe fittings , we should assess the liquid condition . should we use the common steel material?  or we choose the wear resistant steel ? or we should arrange the wear resistant coating or lining materials? like the cement lining or ceramic lining?

  2. The special treatment for the pipes or pipe fittings,  for example , the steel elbows. The outer radius of the elbow is grinded most seriously, maybe we can add some thickness to this part of the elbows.  This is also happened to other pipe fittings, like tees , reducers.

  3. To the steel pipes , concentric reducers and caps ,  they can rotate in any degree in the piping system . When they are in the horizontal direction ,  due to wear of the maximum bottom, on both sides, followed by the top of the minimum, therefore, the pipes an fittings could periodically inverted, it will extend the life of the piping system .

  4.The position, direction and the angle of the pipe fittings also will effect the abrasion situation . if the position is not suitable , the flowing liquid will cause cavitation. The cavitation will speed up the abrasion of the pipings

  We have adopted advanced production equipment and technologies to manufacture our ASTM A106 Gr.B Seamless Steel Pipes and Large diameter welded steel pipe, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
