DN20 stainless steel seamless pipe with a wall thickness of 1 5 mm can withstand how much water pres

How much water pressure can it hold.

Answer: Answer: Steel pipes are divided into thick-walled pipes and thin-walled pipes, and the formulas for calculating the internal pressure are different, and the pipes with k=d d are called thin-walled pipes; The tube of k=d d> is called a thick-walled tube.

The maximum allowable internal pressure of thin-walled pipes [ p ] is calculated as: [p ] =2[ s (d+s) where: [ allowable stress of the material.

- Weld coefficient, for seamless pipes, =1;s--Pipe wall thickness; d - inner diameter of the tube.

The maximum allowable internal pressure of thick-walled pipe [ p ] is calculated as: [p ] = [ k 2-1) (k k 2) where: k = d d

Source of the formula: Calculation of thick-walled cylinders and thin-walled cylinders in the Pressure Vessel Design Manual.

Steel pipes belong to thin-walled pipes, which are calculated according to this formula: [p ] =2[ s (d+s).

Low pressure: maximum bearing pressure = working pressure;

Medium pressure: maximum bearing pressure = working pressure.

High pressure: Above: maximum pressure = working pressure.

Summary. The outer diameter of the stainless steel pipe is 20mm, the wall thickness is 1mm, according to GB T formula 1, the thickness negative deviation, corrosion allowance, weld coefficient, can withstand the maximum working pressure of 83 kg.

The outer diameter of the stainless steel pipe is 20mm, the wall thickness is 1mm, how much pressure can it withstand?

Hello dear, it is my honor to answer your questions, it will take a little time to sort out the answers, please be patient

The outer diameter of the stainless steel pipe is 20mm, the wall thickness is 1mm, according to GB T formula 1, the thickness negative deviation, corrosion allowance, weld coefficient, can withstand the maximum working pressure of 83 kg.

DN200 is 219 mm in diameter, 6 mm in wall thickness and weighs kilograms per meter.

The weight calculation formula of ordinary carbon steel, alloy steel and seamless steel management theory is:

w= -- the density of the steel is taken.

Note: Weight per meter kg m = (outer diameter - wall thickness) * wall thickness * unit taken in mm: mm

So the weight per meter of 403*16 seamless steel pipe is:

403-16)*16*kg m.

Approximately! The calculation formula refers to GB T14976-2002

It is advisable to consult a steel trader.

Compared with ordinary steel pipes, seamless steel pipes are subjected to higher pressures. Therefore, in industrial production, pipes that need to withstand greater pressure are generally made of seamless steel pipes. Some people hail it as the "tiny blood vessels of industry", whether it is to make airplanes, ships, trains, or to transport oil, gas, and water.

The weight calculation formula of ordinary carbon steel and alloy steel management theory is:

w= -- the density of the steel is taken.

Note: Weight per meter kg m = (outer diameter - wall thickness) * wall thickness * unit taken in mm: mm

Therefore, the weight of 630*14 steel pipe per meter is:

630-14)*14*kg m.

The weight calculation formula of ordinary carbon steel, alloy steel and seamless steel management theory is:

w = note: weight per meter kg m = (outer diameter - wall thickness) * wall thickness * unit in mm: mm

According to the material of the pipe (i.e., the type of steel), steel pipes can be divided into: carbon pipes, alloy pipes, stainless steel pipes, etc.

Carbon pipes can be divided into ordinary carbon steel pipes and high-quality carbon structural pipes.

Alloy pipes can be divided into: low-alloy pipes, alloy structural pipes, high-alloy pipes, and high-strength pipes. Bearing tubes, heat-resistant and acid-resistant stainless tubes, precision alloy (such as Kovar) tubes and high-temperature alloy tubes.

The weight calculation formula of steel management theory: w = wall thickness x (outer diameter - inner diameter). Meter weight:

w= d=outer diameter s=wall thickness.

The outer diameter of DN200 is 219 and your wall thickness is 4mm

219-4)x4x0,0246615 = kg.

Pipes are used in a wide range of applications. Tubing is used in many industries.

Different industries have different characteristics of different industries, so they have different technical requirements.

Pipe is a relatively mature product, and various industries have corresponding technical standards.

Detection of pipes, according to the industry of pipe application, select the corresponding product standards, and test the technical indicators according to the needs of the industry.

Generally, there are size indexes, inner diameters, outer diameters, wall thicknesses.

Strength index, the strength index of the pipe includes radial compressive strength, i.e., ring stiffness, compliance index, bending index, impact strength, etc.

For pipes used in drinking water, there are technical indicators for hygiene, as well as indicators for water pressure.

For the communication industry, there are also other technical requirements.

The pressure that stainless steel water pipes can withstand is negatively correlated with the outer diameter of the pipe, and the larger the outer diameter of the pipe of the same thickness, the lower the pressure it can withstand; The pressure that stainless steel water pipe can withstand is positively correlated with the thickness of the pipe, and the thicker the pipe thickness of the pipe with the same outer diameter, the greater the pressure it can withstand; The larger the outer diameter of the tube of the same series, the thicker the thickness; How to calculate how much pressure the seamless steel pipe can withstand Allowable stress = f a First: allowable pressure r = yield point 235 * 80% (carbon steel) Yield point 235 * 70% (stainless steel) Second: wall thickness s=p*d 2r=1*200 (2*235* or this is related to the pipe diameter, calculation formula:

The pressure that the pipe can withstand (mpa) = the tensile strength of the pipe (mpa) x the wall thickness of the pipe (m) the inner diameter of the pipe (m) The calculated pressure can be divided by the safety factor. For example, if the tensile strength of the seamless steel pipe with an outer diameter of 121mm and a wall thickness of 5mm is 500MPa, then its bearing pressure is: 500 x If the safety factor is taken as 2, the actual bearing pressure is also reversed, and the wall thickness can be calculated by knowing other data.

It can be inferred according to the hydrostatic test 2SRP = DP - test pressure MPAR - allowable pressure (carbon steel alloy steel is the yield point, stainless steel is the yield point.

Pro, the national standard (GB8162 8163-87) seamless steel pipe DN120 is 108. Wall thickness 4 28mm - a total of 28 different wall thickness specifications. The raw material for rolling the national standard steel pipe is a round tube billet, which is cut and processed by a cutting machine with a length of about 1 meter, and sent to the furnace by a circular conveyor belt to add sock cavity ridge heat.

The billets are heated in a furnace at a temperature of about 1,200 degrees Celsius. The fuel is hydrogen or acetylene. Temperature control in the furnace is a key issue, and the round tube blank must be hollowed through a pressure punching machine after leaving the furnace.
