Elastic shock absorbers are destined for mounting such equipment as generating sets, main engines, compressors, fans, etc. Elastic fixing limits vibration propagation transferred from equipment to a ship's hull and reduces dynamic loads transferred by vibrating equipment onto a ship's foundation. It also separates the device from dynamic loads transmitted from the adjoining machines.[...]

Ship's glands for electric conductors acc. to PN-69/93600 with a metric thread are destined for sealing electric conductors which pass through bulkheads, walls, decks, etc. and through ship's electrical equipment casings. The glands seal transitions of conductors of 4-57 mm in diameter at differential pressure up to 1 KG/cm2 (0.1 MN/m).[...]

Screwed pipe connections with a cone of 24º are used in ship's pipelines for joining or connecting pipes, fittings or devices for non-aggressive agents of nominal pressure up to 10 MPa, acc. to PN-92/W-74053/01. The range of pressure and temperature rise limits acc. to PN-89/H-02650[...]

Hydraulic clenchings are part of a hydraulic conduit. They consists of an end, clamping socket (sleeve) and a nut, or of an end and a clamping socket (sleeve).[...]

Steel screwed pipe connections with a ring or ball end (conical) are used in hydraulic drives and steering systems in different branches of industry for connecting or joining steel pipes or hoses of nominal pressure up to 16 MPa and 32 MPa, for liquids which do not cause corrosion acc. to PN-79/M-73079. Light series products – L(16MPa) are used for higher mechanic loads, e.g. in high pressure conduits. Heavy series products – S(32 MPa) are used in high pressure hydraulic installations, e.g.[...]
