Formula for calculating pressure on stainless steel pipe
不锈钢管所承受的压力如何计算:
How to calculate the pressure on stainless steel pipe?
1、计算公式:2X壁厚X(抗拉强度X40%)*外径
1. Formula: 2X Wall Thickness X (Tensile Strength X 40%)*Outer Diameter
2、316、316L、TP316、TP316L--抗拉强度:485MA
2, 316, 316L, TP316, TP316L - Tensile strength: 485MA
3、321、304、304L--抗拉强度:520MA
3, 321, 304, 304L -- Tensile strength: 520MA
304不锈钢管的抗拉强度是520MPA 316不锈钢管的抗拉强度是485MPA
The tensile strength of 304 stainless steel pipe is 520 MPA 316 stainless steel pipe is 485 MPA.
而不锈钢管能承受的水压除了材质不同能承受压力值大小不一样之外;外径和壁厚也是非常重要的因素,壁厚越厚,能承受的压力值越大,比如同样外径,10个厚的不锈钢管就比5个厚的不锈钢管能承受的水压要高的多;另外,还与外径有关,外径越大,能承受的压力值越小,比如同样的壁厚,外径越大能承受的压力值越小; 不锈钢管承受压力的计算公式: 水压试验压力:P=2SR/D
The water pressure that stainless steel tube can withstand is not the same except that the material is different and the pressure value is different; the outer diameter and wall thickness are also very important factors. The thicker the wall thickness is, the greater the pressure value can withstand. For example, with the same outer diameter, 10 thick stainless steel tubes can withstand much higher water pressure than 5 thick stainless steel tubes; in addition, there are also outer diameter. The bigger the outer diameter is, the smaller the pressure value can be withstood. For example, the bigger the outer diameter is, the smaller the pressure value can be withstood. The formula for calculating the pressure of stainless steel pipe is: hydrostatic test pressure: P=2SR/D.
S是指壁厚,r指抗拉强度的40%,D指外径; 下面举例说明:
S refers to wall thickness, r refers to 40% of tensile strength, and D refers to external diameter.

小口径无缝钢管一般规格
General Specification of Small Diameter Seamless Steel Pipe
外径在(3mm-42mm)之间的大家习惯称之为小口径无缝管、因为他的直径比较的小.
It is customary to call small-caliber seamless tubes when their outer diameters are between (3mm-42mm) because their diameters are relatively small.
壁厚在(0.8mm-12mm)其实还可以分为:小口径厚壁无缝管、小口径薄壁无缝管.
