Connection of pipes

Now we will talk about connection of pipes. All joints of pipelines should be, whenever possible, folding (carving). It will facilitate the subsequent repair and replacement of separate sites. In an ideal, in general all pipelines of your dwelling incorporate without welding, by a principle of the designer - muftami, sgonami, squares and tees. If subsequently you intend to establish additional to the sanitary technician (to connect a washing machine to put a bidet and a per capita cabin in a bedroom and t, d.), it will be reasonable to provide additional taps ("dummy"), temporarily having closed them zaglushkami.

It is cut a carving

Fix a pipe in a clip or in a vice. If the opposite end already has a carving - screw on it a square with a pipe piece. It will create an additional barrier provorachivaniju. On the pipe end in the width 2-3 mm first of all chamfer. Then oil a cut place. Having chosen a die of the necessary size, it carefully fix in vorotke (lerkoderzhatele) persistent screws. Inserting a die in vorotok, watch, that the brand on a die "looked" aside, opposite to an internal fillet vorotka. The Same party impose a die on a pipe end face strictly perpendicularly to a pipe axis.

Pressing the right palm on vorotok in an installation site of a die, the left hand rotate the handle clockwise. To hurry up here does not follow, the main thing - to provide sufficient effort and necessary accuracy. Will facilitate narezanie carvings vorotok with a directing flange and the plug. In such vorotke the plug is connected to a flange a carving. At work vorotok with a directing flange it is put on a pipe against the stop dies in its end face. Then the plug turn out for length of the future carving and fix on a pipe two bolts. During rotation vorotka the flange will be involved, being screwed on the plug.

we Connect pipes

Various ways of connection of pipes: and - muftami (1 — a pipe with short carvings on the ends, 2 — mufta, 3 — self-made zaglushka with the made end face), — muftami and sgonom (1 - a pipe; 2 - mufta; 3 - a counternut; 4 - consolidation; 5 - sgon) Among themselves pipes incorporate to the help of special transitive elements - fitingov (drawing see). Steels or plastic are produced fitingi from malleable cast iron. Depending on appointment fitingi have the different device. So, on muftah longitudinal ledges on an external part on a turn-key basis are cast. On squares and tees such ledges are absent, as the configuration allows to twist their wrench. Steel fitingi usually smooth, without fillets and ledges. To wrap them it is possible only a trumpet key. Recently have appeared fitingi with graneniem under a usual alligator wrench.

Connecting to the help fitingov pipes with ready (cut at factory) a carving, you will notice that the length of a carving of a pipe is less than half of length corresponding to it mufty. That is at connection of a carving of these pipes will sink in mufte. It is an indispensable condition at joining of pipes in a carving. It should be observed and at independent cutting of a carving. Last threads of a carving have smaller depth, i.e. Diameter of a carving on last coils more than on other carving. Thus, the end of a pipe with the cut carving as though "is shown on a cone". It is made for the best lock-out.

Threads or coils of a carving with smaller depth are called sbegom. Mufta navorachivaetsja on a pipe also it is got jammed on sbege. Now the carving of the second pipe is twisted in this muftu. If the pipe carving appears more long, than the remained carving space in mufte, sbeg it will appear out of mufty and connection will not be tight. Connecting pipes, it is authorised to wrap only pipes and fitingi. Otvorachivanie, "backing", conducts to a leak.

Connections with the help muft - almost not folding also can be applied only there where it is required to "connect" long enough thread of the pipeline. To disassemble such connection, it should to rotate its one site concerning another. Agree, it is not so convenient.

How to be, if it is required to connect among themselves some pieces of a pipe of small length which how you are assured, should have in the subsequent dismantle possibility? (For example, for installation of additional tap or the gate on one of sites.) To facilitate replacement or repair of separate sites of your house pipeline, to connection of pipes among themselves apply other type of a connecting element - so-called sgony. Sgon - a short piece of a pipe, on one end having a short carving (for connection with the basic pipe with the help mufty), and on other - a site with the big length of a carving. On a long site should find room mufta together with a counternut fixing it. The counternut plays a special role - creates consolidation against water infiltration between carvings. It is possible to do without also sgona as separate element, simply having cut longer carving on one of the ends of a connected site of a pipe. The recommended length sgona for semiinch pipes - 90-100 mm.

By the time of connection on a long carving sgona or pipes are already screwed and mufta and a counternut (settles down from outside sbega carvings). For convenience of connection the first coils of a carving leave without consolidation - so easier to "catch" the end of a pipe driven to a junction muftoj. Having wound muftu on a pipe, to it "adjust" on distance of 2-4 mm a counternut. Space between muftoj and a counternut fill with flax or hemp locks, reeling up them towards counternut rotation at a tightening. Being screwed on sealant locks, the counternut will tyre out a sealant part in facets mufty, will jam about-interduck in connection and water between them will not get any more.

To Screw on carving threads before connection of pipes a sealant - business simple. But also here it is important to observe some rules. Sealant locks reel up clockwise, "from themselves" if to hold a pipe the left hand, and having receded on one-two threads from a pipe end face. To avoid blooming, the lock can moisten with water and after that to wrap a pipe in muftu or a square. It is possible to moisten a sealant also with an oil paint, but dismantling of such connection in the future will become complicated. To pipes with hot water apply heat-resistant tape FUM or similar.
