Profile pipes include metal pipes of atypical cross-section - square, rectangular, flat oval. The main purpose of these products is the manufacture of metal structures, where shaped pipes are used as a supporting or decorative element. The frames are assembled using welding or other methods of fastening - rigid and floating. In Moscow, you can buy inexpensively various connecting elements along with rolled pipes.
Rigid pipe connections
The connection of profile pipes by contact and electro-gas welding turns out to be reliable, but not aesthetically pleasing. The joints need painting and corrosion protection. At the moment, a less labor-intensive and technologically simple connection is used using high-quality fasteners:
-
The crab is a universal element that can be used to connect profile metal products in Moscow. It is made of polymer or zinc coated metal. The main application of crab systems is the assembly of simple structures, for example, greenhouses, greenhouses, racks, benches, the construction of small outbuildings, light fences and flower supports.
-
Flanges are more convenient to use for structures of temporary use, subject to periodic assembly and disassembly.
-
Couplings are the optimal fastener for direct connection of pipelines, as they can withstand high pressure and ensure tightness.
-
Fittings are used to assemble complex pipelines. Additional strengthening of the joints by welding is applied. There are fittings for external and internal use, in various shapes to create branches with the same and different cross-sections.
Floating pipe connections
Clips and ties are considered floating fasteners. The craftsman uses clips or clamps made of the same material as rectangular shaped pipes . It attaches to other elements, and the attachment point is tightened with bolts. The advantage of this method is the possibility of assembling a structure from pipes with any section.
Benefits of not welding
The main argument in favor of a non-welded connection is the uselessness of a welded apparatus, which is rarely included in a home repair kit. It is easier for home craftsmen to use more affordable fasteners, which can be ordered on the website https://metallink.ru/at a low price. There are other pluses:
-
Lower installation costs.
-
There is no need to involve specialist welders.
-
Fast execution of work.
If the house does not have the necessary fasteners, you can always order delivery from the online store. When buying in bulk, the price will be cheaper.
When choosing a fastening method, it is important to evaluate the purpose and operating conditions of the structure. In order for a rectangular metal pipe to withstand increased loads, the joints must still be reinforced with welding.
