Water Stainless Steel

pipe stainless steel, black and galvanized pipes.Advantages and disadvantages of

For starters, let's talk about the pipeline made of black steel.It is set, even today, because it is not characterized by high cost, low capacity for deformation at high temperatures as well as good mechanical characteristics.However, it is prone to corrosion, which occurs due to exposure to electromagnetic fields.Such water rapidly grows fat and various mineral deposits, which reduces the tube diameter and its bandwidth.

Galvanized pipe is an alternative to pipes made of black steel.A layer of zinc provides protection and allows you to use the product with a similar coating to ten years longer.They are made using a cold or hot-dip galvanizing, electroplating or thermal diffusion method.Risers and water pipes are connected by welding or on the threads.Welding electrodes are used with a diameter of 3mm.with calcium fluoride or rutile, but threaded connections seal with PTFE tape or other special material.

Galvanized plumbing corrosion resistant, practical and cost effective.The only negative - the occurrence of condensation in a warm room (with passage of cold water in it).

pipe stainless steel for those who do not particularly think about the price.It meets all the norms and standards, a reliable and durable.It is made seamless or welded.It is seamless is the most reliable and durable, but the most expensive.

This water contains in its composition the different alloying elements besides carbon and iron.This chrome provides long life and corrosion resistance.

In recent years, are gaining popularity flexible stainless steel pipe, which is used in complex construction of water supply systems.There are matte, mirror and polished surface, which means that the pipe is characterized by attractive appearance.There are also disadvantages.These include the cost and complexity of installation.Only a professional welder will be able to competently and efficiently carry out the installation.

Standard sizes of steel water pipe

diameter steel water pipe is measured by the internal section in inches.However, when laying it is necessary to pay attention to the outer diameter, as the tube wall may be required for further elongation threading portions.

Let's see how to define the diameter of the pipe using a measuring tool.

1. To measure outer diameter, wrap the pipe tape measure and divide the result by 3.14 (ie, Pi).
2. To measure the inner diameter of the outer diameter subtract twice the wall thickness, which is measured using a conventional ruler or calipers.

As a rule, ordinary steel pipe for hot and cold pipe has a diameter of ½ inch, and the diameter of the riser is equal to ¾ inch.

From the ratio of "diameter-wall thickness" distinguish easy (most often used in gas mains), ordinary and reinforced piping.

Ways of steel water pipe

As we said above, the steel pipes are connected by means of electric, gas welding, or on the threads.Before welding, the need to carefully handle the pipe edge.Place for a weld joint must be cleaned of dirt and corrosion until metallic luster appears.If you do not, weld tend to get brittle and porous.This procedure is done not earlier than four hours before welding.Pay attention to the following points:

• pipe must be free from major defects (small dents can be corrected);
• thickness welding parts must be equal and uniform;
• check the bevel angle and the amount of edges.

number of joints depends on the wall thickness, each seam is applied in the opposite direction to the previous.
