Description

гипроцилиндров, во втором случае впемент 4 ограничивают от расширени  с торцов и попают давление внутрь его, В обоих случа х воздействуют эле ментом 4 на свинцовую оболочку 3 до по влени  в отверсти х 2 выпавленного свинца 5, После вто1Х) давление снимают а элемент 4 перемшцают в соседнее положекие , где вновь создают им давление на стенки, и так до тех пор, пока вс  свинцова  оболочка 3 не будет прижата к трубе 1, а тогда все 2 снаружи заполкшот жидким свишхом 6,in the second case, the tail 4 is limited from the expansion at the ends and the pressure gets inside it. In both cases, the element 4 is exposed to the lead sheath 3 to appear in the holes 2 of the deposited lead 5, After the second pressure is removed and the element 4 is replaced to the next position, where they again put pressure on the walls, and so on until all the leaden sheath 3 is pressed against the pipe 1, and then all 2 outside the container are filled with liquid 6,

Первый случай пригоден дл  труб малых диаметров, второй - дл  больщих.The first case is suitable for pipes of small diameters, the second - for large ones.

TaJKHM образом, соединение вьщавленного свинца в отверсти х с жидким свинцом , заливаемым в отверсти , создает надежное закрепление свинцовой оболочки со стальной трубой.TaJKHM, by combining lead in holes with liquid lead poured into holes, creates a secure fit for the lead sheath to the steel pipe.

Ожидаемый экономический эффект от использовани  предлагаемого способа только в одном кислотном цехе составит в год 30-4О тыс.руб.The expected economic effect from the use of the proposed method in only one acid shop will be 30-4 thousand rubles a year.

1. Способ изготовлени  трубы с зашцтной оболочкой внутри, включающий образование в трубе отверстий, введение в нее защитной оболочки, и заполнение отверстий жидким металлом, отличающийс  тем, что, с целью повышени  надежности соединени  оболочки с трубой, предназначенной дл  работы под знакопеременным давлением, перед заполнением отверстий трубы жидким металлом на оболочку изнутри воздействую давлением до по влени  в отверсти х выдавленного металла оболочки.1. A method of manufacturing a tube with a sheath inside, including the formation of holes in the pipe, the introduction of a protective sheath into it, and filling the holes with liquid metal, characterized in that, in order to increase the reliability of the connection of the shell with the pipe, intended to work under alternating pressure, filling the openings of the pipe with liquid metal on the shell from the inside by the action of pressure until it appears in the holes of the extruded metal of the shell. 2. Способ по п. I, о т л и ч а ющ и и с   тем, что в трубу ввод т защитную оболочку из свинца.2. A method according to claim I, in respect of the fact that a lead sheath is introduced into the pipe.
