NPO Poisk

Cylinders with a lightweight plastic cased TU 1411-001-03455343-2002 (instead of TU 1411-001-03455343-97).

Cylinders with a lightweight plastic cased TU 1411-001-03455343-2002 (instead of TU 1411-001-03455343-97).


First 3 litre cylinders have been made NPO "POISK" in 1992. The cylinder consisted from thin-walled welded leiner of stainless steel and organic-plastic covers. Further some changes have been made to a cylinder design, concerning a kind and a way of welding, and also process of winding of a cover is optimised. Now cylinders are issued on TU 1411-001-03455343-2002.

                                                                                                

                                                                                                                                                                                                                           



Cylinders are issued two types (oxygen BK and gas BG), ten kinds (5 kinds capacity - 1, 1,5, 2, 2.5, 3, 4 litres and 2 kinds of a plastic cover - organic-plastic on pressure of 31,4 MPa and fiberglass on pressure 21,6 MPa) and three executions of the union.
