Classification of profile steel pipe

Features production profile metal.

When you sort of rolled metal products account for options:

• Footage pipe;
• rolled cross-section;
• Profile Form.

As additional indicators taking steel grade (using carbon, alloy and high) and the presence or absence of a galvanizing.

The most popular forms of rolled products are: square, rectangular, oval, teardrop-shaped, multi-faceted

For technological manufacturing processes, they are divided into:

• Seamless;
• Cold-;
• Electro (suture);
• Hot rolled;
• Electro cold-

service life of rolling of pipes, due to its anti-corrosive properties, significantly increases the deposition of the zinc coating (galvanizing).

Since the profile pipes have qualities such as strength and flexibility, they are able to provide rigidity, while the weight is about 30% less than the weight of the same all-metal segment.

addition, the release are still a number of significant advantages:

• Economical, thanks to its low weight at high loads, and ease of installation;
• low metal content;
• Fire (ability to lay electric cables in the cavity of the tube).
• Convenient transportation and warehousing.

Omitting all the details of the process of production, there are several main stages of production:

• heating the workpiece before rolling;
• Folding hot billet, followed by welding the weld connection or by cold deformation;
• The transmission pipe through special rollers, which give it the appropriate form;
• Required control of the weld;
• heated to a certain temperature for stress relief.

standards used for the production of profiles.

Rolling in its work on the production of steel pipes are strictly guided by certain standards:

• GOST 8639-82 - regulates the release of square steel tubing;
• GOST 8645-68 - for rectangular products;
• GOST 13663-86 - subjugates manufacturing different ways sectional steel.
• GOST30245-94 - standard for closed welded profile pipes.

Application of profile steel pipe.

Scope specialized products rather extensive:

• in mechanical engineering;
• furniture industry (the legs of chairs, tables, etc.);
• construction (production of frames for greenhouses, ladders or intermediate floors);
• Design (as decorative finishes).

Production greenhouses made of steel pipes.

Build a greenhouse at their summer cottage with his hands it is possible to have quite some skill and create the drawing correctly.The basis of this design is the skeleton, the strength of which will depend on the durability and stability of the greenhouse.That is why karkasyteplits steel pipes are very popular among gardeners.This material does not corrode and arch ribs themselves are quite stable under mechanical and atmospheric loads.

Where to buy profile pipes.

There are several ways to purchase pipes.This can be done by contacting the manufacturer directly.And the cost is much cheaper than to buy in DIY stores or Metal.If you decide to make a purchase on order, then you have the opportunity to get your desired product size and section.The number and parameters are specified when ordering.
