The main stages of assembly of pipelines - 1 part
Many pipelines have difficult spatial structure and contain a number of different details, such as branches iron, transitions iron concentric or tees shtamposvarny.

Assembly of parts of pipelines is not difficult and consists of several steps:

1. Before pipe assembly, iron and other details laboriously smooth out tees, releasing them from stuck грязищи, scales and rusts. It is most ideal to create cleaning by means of the electronic or Continue reading

History of pipes of

History of pipes of
The 1st standards of pipes can be met in historical chronicles of times of the Roman Empire, also at excavation of the cities of the Old East. At that time they were made of a tree, namely – a bamboo, also from clay, and did one of 2 functions or worked as a water supply system, or – as sewer branch. But already in Old Rome started to try to create pipes from metal, in particular from lead of which was at that time extracted very much and it Continue reading

It is necessary to hold in the head that welding of welded pryamoshovny pipes has certain features, namely, seams of adjoining pipes should be shifted on the third part of length of a circle (40мм and least) or on 100мм (a diameter more pipes more 100мм). Flanges iron are welded so that the mirror of a flange was strictly perpendicular to a pipe axis that is reached by introduction of a special square.

The distance from a welded seam prior Continue reading

Systems of the sewerage
Systems of the sewerage represent built in walls, a floor, the earth of a pipe which are created for a conclusion, also removal of the rain water, the fulfilled water, from the house, a yard, inhabited yards, streets, the areas, roads. Systems of water drainage exists strongly much, but we will make out systems of the sewerage more popular and quite often used in modern construction.

For pipeline laying though what mission, high-quality pipes are necessary. There are many versions of such products suitable for these purposes as creation of accurate equipment, cryogenic equipment, a pipe are used in shipbuilding, aircraft industry, mechanical engineering, in a car and the chemical industries. But we will have a talk about the goryachedeformirovanny.

Pipe seamless goryachedeformirovanny GOST 8732-78 assortments on an external Continue reading

Plastic pipes of

For many years iron pipes were a basis actually all systems of water supply. But a zaintrigovannost in increase in durability of systems and as in fall of their metal consumption, always set thinking on application of the pipes made of new types of materials. For today polymers (base of all plastic pipes) became such other materials. The beginning of introduction of these materials opened the latest era in the history of water supply. For today Continue reading
