MP(Mechanical Polishing) Stainless Seamless Pipe

Polishing refers to the machining method of using mechanical, chemical or electrochemical action to reduce the surface roughness of the stainless steel pipe, so as to obtain a bright and flat surface. It is to use polishing tools and abrasive particles or other polishing media to modify the surface of the stainless steel pipe.

Stainless steel pipe polishing is divided into two parts: inner surface polishing and outer surface polishing. Most of the stainless steel tube polishing is mechanical polishing, if the precision requires higher use of electropolishing.

Mechanical polishing pipes are generally prohibited from being processed by mechanical polishing to reduce the surface roughness of the pipe wall and achieve a smooth and clean effect. the outside can be provided in mill finish, bright finish, 180 grit polish, 240 grit polish, 400 grit polish, and even finer depending on customer requirements.

Mechanical polishing is used to provide a homogenous and bright appearance. It is accomplished by grinding the tubing with finer and finer abrasive grits to achieve the desired finish or surface roughness. Tubing can be provided in a variety of surface finishes on the Outside and Inside Diameter based on customer requirements.

For ornamental purposes, For sanitary tubing, the outside and inside are polished to provide a smooth finish to avoid biological buildup on the tubing service. Mechanical polishing can also be used to prepare tubing for electropolishing so that the final desired surface finish is successfully achieved.

Advantages

– high brightness

– Improve surface finish , Better surface cleanliness 

– Reduce product adhesion

Disadvantages

– The gloss cannot be consistent and cannot last

– May be susceptible to corrosion

– The mechanical strength of the surface is weakened
