What is the difference between a clamp butterfly valve and a flange connection?1, The structure is different: flange connection is the bolt to connect the two end faces together; The clamping type is to squeeze the two sealing rings together by the nut to ensure the tightness of the connection.2, Th

Stainless steel welded round pipes are a popular choice for various applications due to their durability, corrosion resistance, and aesthetic appeal. Here are some key features and benefits of stainless steel welded round pipes:

Effect of gasket on tightness of flangeThe bolt flange connection is composed of a pair of flanges, a number of bolts, nuts and a gasket. The flange is sealed by tightening the bolt and pressing the gasket. However, the sealing performance of the flange depends on the following factors. For example,

The difference in performance between LR and SR elbowsLR elbow: Long radius elbow means that the curvature radius of the elbow is 1.5 times the diameter of the pipe.SR elbow: Short radius elbow means that the curvature radius of the elbow is equal to the diameter of the pipe.

Malleable steel pipe fittings and galvanized pipe fittings have differences in material, coating, scope of use, manufacturing process, corrosion resistance and so on. Therefore, when choosing accessories, it is necessary to choose according to the specific situation, so as to ensure the quality and use effect.

How is seamless pipe produced?The production method of seamless steel pipe is roughly divided into the diagonal rolling method and the extrusion method.The miter rolling method is to first perforate the tube embryo with a miter roll and then extend it with a rolling mill.
