Seamless steel pipe occupies an important position in the national social economy. Maybe everyone doesn't understand it very well, but it has been widely used in petroleum and chemical management, which has brought a new experience to people's lives. Great convenience. Seamless steel pipes are also divided into many categories in my country, among which Chinese stainless steel pipes are widely used by students in an ideal living environment.


It is not difficult to find in life that the garden fences and stair handrails that people see are all made of stainless steel pipes. The stainless steel pipe is small in size, which is convenient for people to install. It also has good corrosion resistance, which reduces many unnecessary expenses, especially when it is used as a garden fence, it will not corrode in wet environments. Stainless steel pipes also have strong toughness, but this toughness is directly related to the size of the hole diameter.


As a support, the diameter of the stainless steel pipe is usually smaller than the diameter of the guardrail. Therefore, friends, during the buying process, buy seamless steel pipes according to my needs. Straighten the seamless steel pipe, stop the soot blowing during the initial inspection, and determine the length of the cutting head and tail. The purpose of seamless steel pipe cutting is to clean up the cracks, scars, scars, tears and uneven wall thickness of the pipe end to obtain the required length of seamless steel pipe inward folds, inner scars, severely uneven wall thickness, etc.


Before the operation, the common cutting line is stopped, and then through the cutting holding time, it should be ensured that the complete combustion of the steel through the furnace can be controlled. Some organizational changes in performance. The normal progression of the heating temperature can appropriately shorten the holding time. When the low temperature annealing is stopped (including softening, stress relief and recrystallization annealing), the annealing temperature is closer to the critical point A1, the faster the response is, the more complete the elimination of work hardening effects, and therefore, the holding time can be appropriately shortened.
