Usually we use the American Smooth Grease Institute (NLGI) classification specification; the smooth grease is divided into nine grades such as 000#, 00#, 0#, 1#, 2#, 3#, 4#, 5#, 6#; To indicate the softness and hardness of the smooth fat. The lower the grade, the harder the smooth grease is. Usually; the hardness is slightly larger under high temperature and heavy load conditions. Others; we usually rely on the smooth fat "dropping point" Functional indicators to determine the highest temperature that smooth grease can get used to.
Most of the smooth grease used in automobiles is used for the chassis; especially in the hub bearing; the amount of smooth grease used in other parts is less. How can we get smooth grease suitable for personal car when using smooth grease? What?
First of all; when choosing smooth grease, it is necessary to determine the working environment and temperature of the part. For example, some high-speed bearings; and some other machines that operate in high temperature environment; it is necessary to select high-quality smooth grease with high dropping point. Usually lithium The base smooth grease can withstand the operating temperature of about 120 ° C; the short time can withstand the high temperature of 180 ° C, and the composition of the grease can withstand higher temperatures (dropping point above 300 ° C). Usually the wheel bearing of the vehicle is smooth selection 2 #, 3 #lithium grease and lithium complex grease can be.
Others; we should also consider the mechanical load and the need for extreme pressure function. For some large trucks, the wheel bearings of heavy overload vehicles should use better smooth grease such as extreme pressure and mechanical stability; 3# extreme pressure lithium complex grease or composition smooth grease.

Sameless pipe
Seamless pipe as the name suggests is a pipe without a seam or a weld-joint in contrast to Seam or Welded pipe. In a Seam or Welded pipe, the seam or the weld-joint is the weaker part of the pipe limiting the strength of the pipe to the strength of the weld-joint. Whereas the seamless pipe does not have any such joint and thus has uniform structure & strength all over the pipe body.
Some commonly used models are
Api5L Seamless Pipe ,A53 Gr.B Seamless Pipe,Astm A106 Gr.B Seamless and so on.Advantage
The seamless pipe can withstand higher pressure, higher temperature, higher mechanical stress & corrosive atmosphere and find wide applications in Oil & Gas.
Applications
Applications in petrochemical, chemical, chemical, chemical fertilizers, electric power, automobiles, bearings, machinery and structures.
API 5L Seamless Steel Pipe ASTM A106/A53 GR.B seamless steel pipe
Standard of carbon seamless steel pipe
