Seamless steel pipe network share knowledge of 27siMn seamless steel pipe

27simn seamless steel tubes, ie 27SiMn seamless steel tubes, are one of the materials for seamless steel tubes. The carbon content is between 0.24 and 0.32%. The simn single row is because of the five elements (carbon C, silicon Si and manganese). In Mn, phosphorus P, and sulfur S, the content of silicomanganese is about 1.10 to 1.40%. 27simn seamless pipe is suitable for power plant, boiler plant, chemical industry, car, ship accessories.
27SiMn, alloy structural steel. Unified digital code: A10272
Standard: GB/T 3077-1999
【Main Features】
The performance of this steel is better than 30Mn2 steel, high hardenability, critical quench-through diameter in water up to 8 ~ 22mm, good machinability, cold deformation plasticity and weldability; In addition, the toughness of steel in heat treatment is not much reduced, However, it has relatively high strength and wear resistance, especially when water quenched, it still has high toughness; however, this steel is sensitive to white spots, and has tempering brittleness tendency and overheating sensitivity during heat treatment.
【Application examples】
This steel is mainly used in the tempered state for the manufacture of hot stamping parts requiring high toughness and wear resistance; it can also be used in the normalized or hot rolled state of supply, such as the tractor's track pins.
27simn seamless steel pipe calculation formula seamless steel pipe weight per meter W=0.02466*S(DS)
Symbol Meaning: D = Outer diameter S = Wall thickness calculation example: For a seamless steel pipe with an outside diameter of 60mm and a wall thickness of 4mm, calculate the weight per m.
Weight per m=0.02466*4*(60-4)=5.52Kg

Stepper Motor Peristaltic Pump

The stepper motor Peristaltic Pump can be used alone with the control program developed by our company, or it can be used with the customer's own PLC control program.

The integrated circuit board specially designed by our electronic engineers can be used with NEMA23 stepper motors, and try a variety of pump head pump tubes at the same time. Support the function customization of Modbus protocol and analog control. The size of the circuit board is as large as the palm of the hand, but its functions are comparable to the digital peristaltic pumps on the market. UCP series peristaltic pumps have compact structure, small volume, powerful functions and high precision. It is suitable for various medical equipment, analytical instruments, packaging machinery, etc.
