Elbow, 45 DEG, CL3000, SW, NB/T 47008 20,, SH/T 3410. What do DEG and SW mean in CL3000? What are those English abbreviations?
"DEG is an abbreviation for “Degree”; it denotes the angle of bending here, and 45 DEG means that the bending angle of this elbow is 45 degrees. "SW” is an abbreviation for “Socket Weld,” which is a welding method primarily used for connecting fittings together, or between fittings and valves. Therefore, the string \"Elbow,45 DEG,CL3000,SW,NB/T47008 20,,SH/T 3410 ,CL3000\" describes a 45-degree socket weld elbow with a grade of CL3000, in compliance with the standards NB/T47008 20 and SH/T 3410. .
deg: The unit for measuring angles in degrees; 45deg means an angle of 45 degrees. SW: Socket weld. Total: Elbows, 45-degree angles, 3000 pounds of strength, 3410 standard socket weld fittings; material: 47008 forged 20# steel.
CL3000, that is CLASS 3000, refers specifically to the classification of pipe fittings; it has no unit.
