26.05.2018

Galvanized water pipes- These are popular products made of steel. They have galvanized - this processing of products with zinc layer. This procedure helps increase corrosion resistance.

By guest 3262 75 Steel water pipes galvanized pipesproduced everywhere. They are made of carbon steel, their shape is cylindrical, the length of the structure has a welded seam. Pipes differ in the thickness of the wall: fat, thin, medium. Depending on the desired project, you can choose this or that product.

Galvanized water pipe pipe GOST 3262 75 is made from steel strips that pass molding and welding. The regulatory document for which they are produced is a state standard.

Galvanized water pipe pipe GOST 3262 75 is made from steel strips that pass molding and welding.

What can I buy galvanized water pipes?

Naturally, such pipes are used for gas water pipes and plumbing systems. For example, the gas pipeline can be made of a thin-walled profile. This choice is due to the fact that gas produces not particularly significant impact on the design of the pipe.

The thickness of the walls of the system is the indicator of strength.

If you create a hot water supply, then you should preferably get HSV products with thick walls, and if cold, then you can purchase pipes with the average sizes of the walls. Of course, it is advisable for water supply to order galvanized pipes - the zinc layer will significantly extend their service life.

What is the current price for the water pipeline?

The definiteness of such a pipe can be using the order form on our website. Enter the order settings, and the system independently calculates the price. On the pipe GOST 3262 75 Price varies, depending on the set of indicators. This is the size, and length (from 4 to 12 meters), and the wall thickness, and the material of the manufacture.

Is it possible to save on the tallers 3262 75? The answer is simple: you can, but not need. The most accessible option may be the most short-lived. Please note that galvanized profiles have weight, 3 percent is greater than pipes without zinc layer. However, the probability of corrosion will be significantly reduced. Accordingly, such a pipe will serve much more, not requiring fixing and replacement.

In our company, you can purchase any kinds of similar pipes by ordering direct delivery to the place of construction or installation you are interested in.

The main properties of galvanized products

As for the technical properties and advantages of pipes with galvanized spraying, several of them can be distinguished:

Compared to plastic pipes, galvanized metal products have high strength. What to say if plastic easily can be deformed with an ax, a knife. Metal rolling, similar to inventory, do not deform. Constant value. Galvanized and other types of metal products do not succumb to the temperature expansion. The process temperature range - metal pipe It does not threaten the effect of thermal steam. High pressure incoming fluid in pipes. Resistance to corrosion, which is achieved by coating the inner and outer part of the pipe with zinc. The antiseptic properties of zinc are known, so infections do not develop in galvanized pipes.

The advantages of meaningful weight, it is they who do not give plastic to finally push the metal from the construction market.

Types and sphere of using galvanized pipes

The difference between galvanized pipes and ordinary is that the first are exposed to "galvanized". In the construction case today appear next species Pipes: water-gas pipe. This type of product is manufactured according to standards and is applied when installing water, gas pipeline systems only indoors. The length of the pipe is from 4 - 12 m.Electrosive pipe is made from the standard steel type. We use it exclusively in agricultural buildings, mechanical engineering. The length of the product ranges from 4-12 m, and the diameter ranges from 11-48 cm. Pinophilic tube. Its difference from the previous types is an extraordinary cross section (square or rectangular shape). As a versatile tube is universal and is used everywhere. It is produced from alloy steel, which already indicates its high quality and durability.

All types of galvanized pipes have a good performance, and taking into account the masses are divided into three categories: light, standard and reinforced.

Mechanical engineering, construction, exploration of deposits, gas, water, oil - to imagine a branch of the economy in which the pipes would not be involved, is very difficult.

In domestic conditions, owners of apartments and country houses It is often necessary to deal with water and gas pipeline and sewer pipes.

Metal products: Classification

Pipeline gasket automatically implies the production of pipes of a variety of classes and sizes. Metal products produces round, oval, profile products, designed for a variety of conditions: from the supply of drinking water before performing the role of support when developing oil-producing wells. In this case, the characteristics depend largely on the manufacturer's method than from the composition of the source material.

Seamless - produced by hot or cold molding on rolling mills.
Welded - manufactured by welding metal sheet (electric arc, induction high-frequency currents and so on). This method of production is cheaper, and the amount of product strength is quite sufficient for use in most areas of the national economy.

Welding can be done in two ways:

on the junction of the stroke or on the axis product, received the greatest distribution in the organization of water and gas pipelines;
spirals - the harvesting tape is fitted with a spiral and is brewed in the same way. This technology allows you to get electric weld pipes with higher tensile strength.

The method of processing the workpiece also affects the properties. Under this feature, long-scale products are divided into groups:

hot-focused - manufactured with heat treatment;
cold-deformed - forming of the workpiece is made without heating. This method reports the product high strength and anti-corrosion resistance.

The size of the diameter of the pipe fluctuates in a very wide range - from 5 mm to 550 mm. The length of the product depends on the diameter. Product parameters are standardized GOST. For example, electric welded galvanized products are governed by GOST 10704-91. The photo shows the sample.

Pipeline for home: Classification

For the organization of the water and gas pipeline in residential areas, a welded pipeline is used, since its strength characteristics fully correspond to the task. However, when choosing it is recommended to give preference to galvanized pipes.

Zinc is the process of metal coating, in this case steel, a protective zinc layer. The latter is not destroyed by moisture and, accordingly, protects iron from corrosion.

The layer thickness on the electric weld pipeline is at least 30 microns. This increases the mass of the product by 2-3%.

According to GOST 10704-91, pipes are produced in conventional and high precision, with sliced \u200b\u200bor touching threads, as well as without thread. The measuring length is 4-12 m.

In private construction, 1 class of products designed for water supply, gas, hot water and so on.

How to calculate the mass of round electric welding pipe

GOST 10704-91 contains weight indication 1 running meter Pipeline. In practice, there are quite often situations when it is necessary to calculate the mass of a particular product. The value may differ, since the same GOST 10704-91 includes instructions on the allowable deviation.

Necessary parameters

Outer diameter - actual.
Wall thickness.
Material brand - the density of various types of steel is noticeably different.

Calculation of weight by volume

Suppose external diameter electric welded pipe It is 152 mm, and the wall thickness is 5 mm. In order to calculate the weight of the route meter, it is necessary to calculate the volume of the product (sheet) and multiply to the density of steel.

The circumference length is calculated as a piece of diameter by the number Pi: \u200b\u200b0.152 * 3,142 \u003d 0.477584 m.
The surface area is a product of the circumference of the product length: 0.477584 * 1 \u003d 0.477584 square meters. m.
The volume of steel used for manufacture is located as a piece of surface and wall thickness: 0,477584 * 0.005 \u003d 0.00238792 cubic meters. m.
The density of the steel grade is determined by reference tables. Suppose it is 7850 kg / cubic meters. So, it means to calculate the mass of the pipeline in this way: 0.00238792 (material volume) * 7850 (steel density) \u003d 18,745 kg.

Calculation of weight by formula

You can apply a shorter method of calculation. The formula is used to determine the mass of exactly 1 meter.

M \u003d 3,142 * (D-E) * E * R, where:
M \u003d weight of the product;
D \u003d external diameter;
e \u003d wall thickness;
r \u003d material density.

Weight, respectively, will be equal: 3,142 (0.152-0.005) * 0.005 * 7850 \u003d 18,128 kg.

Different methods give the results different from each other. The main thing in this case is the range of obtained values: they should be inside the tolerance that is established by GOST.

The mass of galvanized electric weld pipes is higher than steel, so the result obtained should be increased by 3%: 18.745 * 3% \u003d 19.325 kg.
