Types of structural materials used in the manufacture of pipes

Advantages and disadvantages of the pipe metal

following materials used for the manufacture of metallic communication:

1. iron.
2. «black" steel.
3. Stainless Steel.
4. Copper.
5. Aluminium.

For each pipe rolled peculiar characteristics of those who have appeared in his thanks to structural materials.

Cast iron has a long service life, but he too is fragile and very heavy, which is its major drawback.In addition, the iron very slowly corrode, but not as ductile as steel.

Pipes of "black" steel rust quickly, but nevertheless strong at different loads.Due to less weight than that of cast iron and steel pipes can be made large size.

Stainless steel pipes speak for themselves.They possess all the above qualities of "black" steel, but their corrosion does not take.Therefore, it is durable and long-lasting option for plumbing pipes.They can even withstand boiling acid.

Copper pipes are characterized by good ductility, thermal conductivity, strength.Therefore, a copper producing thin-walled tubes.The disadvantage of copper products is their heavy weight and high cost products.

Finally, aluminum is light in weight, corrosion resistance, low cost.Aluminum is also used as a reinforcement in the reinforced plastic pipes.

sizes metal pipes

Settings pipe rolled, what metal they would not have been made, they are determined by the length, wall thickness, outer diameter rolled steel.In addition, design calculations take into account a parameter such as a nominal diameter which depends on the internal diameter.Numerical values ​​of the parameters depend on the method of manufacturing the product and the type of material of construction.

Settings pipe rolled steel (black and stainless).

Depending on the mode of production sizes are:

1. Hot rolled pipes have such values:

• outer section along the verge - 60-180 mm;
• outer diameter - 20 -550 mm;
• wall thickness - 2.5 - 75 mm;
• pipe length 4-12,5 m

1. Cold-rolled steel has the following values:

• outer section along the verge - 10-120 mm.
• outer diameter - 5 -250 mm;
• wall thickness - 0.3 - 24 mm;.
• pipe length of 1.5 m -11

Stainless steel products have several other dimensions:

• outer diameter - 5 -273 mm;.
• pipe length 1,5-25 m

rental dimensions manufactured by the method of folding the weld depend on the type of weld:

1. for longitudinal welded pipes are characterized by:

• outer section along the brink of - 10-230 mm;
• outer diameter - 10 -1420 mm;
• wall thickness - 1 - 32 mm;.
• pipe length 2-12 m

1. products made by twisting the intermediate product and further spiral seam welding parameters are:

• outer diameter - 159 mm -2.52 m;
• wall thickness - 3.5 - 25 mm;
• pipe length of 10-12 m.

Dimensions of pipes made of cast iron

For products made of cast iron is not characteristic of the variety and assortment of production is the only way to hire.

• outer diameter - 50 -150 mm;
• wall thickness - 4 - 5 mm;.
• pipe length 0,75-2,2 m

Dimensions of copper pipes

Rolled and welded copper products according to the specifications have the following dimensions:

• outer section along the verge - 30-280 mm;
• outer diameter - 3 -360 mm;
• wall thickness - 0.8 - 10 mm;
• pipe length of 1-10 meters.

pipe sizes from the aluminum

Production of aluminum tubes is folding, pressing.folding method by pressuring the joints used for the manufacture of corrugated pipes with diameter 80-310 mm.Compressed products are produced with a diameter 18-240 mm, wall thickness 1.5 - 40 mm, a length of 6.1 meters.Other parameters are determined by GOST 18482-79.
