- Axial expansion joint, type OPN (OPNR). An expansion joint consisting of a bellows and connection branch pipes further welded to a pipeline.
- Axial expansion joint, type OPG. An expansion joint consisting of a bellows and connection branch pipes further welded to a pipeline, with a mounted internal guide pipe.
- Axial expansion joint, type OPFN. An expansion joint consisting of a bellows and connection branch pipes further welded to a pipeline, with mounted bearing flanges.
- Axial expansion joint, type OPK. An expansion joint consisting of a bellows and connection branch pipes further welded to a pipeline, with a mounted fixed non-load bearing casing.
- Axial expansion joint, type OPM. An expansion joint consisting of a bellows and connection branch pipes further welded to a pipeline, with a mounted fixed non-load bearing casing and an internal guide pipe.
- Axial expansion joint, type OPKR. Single-bellows and double-bellows expansion joints consisting of one or two bellows and connection branch pipes further welded to a pipeline, with a forced double (extensible) casing. The design provides for protection from hyperadmissible bellows deformations (tensile-and-compression limiters). The outer surface of bellows and branch pipes has a corrosion-resistant waterproof coating.
- Axial expansion joint, type OPMR. Single-bellows and double-bellows expansion joints consisting of one or two bellows and connection branch pipes further welded to a pipeline, with a forced double (extensible) casing and an internal guide pipe. The design provides for protection from hyperadmissible bellows deformations (tensile-and-compression limiters). The outer surface of bellows and branch pipes has a corrosion-resistant waterproof coating.
- Axial expansion joint, type KSO (KSOR). Single-block and double-block expansion joints consisting of one or two bellows and connection branch pipes further welded to a pipeline, with a mounted forced double casing and outer guides. The design provides for protection from hyperadmissible bellows deformations (tensile-and-compression limiters), inspection windows in the casing and a rule for bellows condition monitoring in the course of operation. The outer surface of bellows and branch pipes has a corrosion-resistant waterproof coating.
Bellows expansion joints of the OPK, OPM, OPKR, OPMR types are intended for installation in pipelines of heating networks and hot water supply, as well as steam pipelines during ground laying, indoors, as well as during underground laying in tunnels, through and non-through channels and thermal chambers, thermal insulation of which is applied after installation with various thermal insulation materials: mineral wool and basalt wool mats, polyurethane foam shells with a non-flammable waterproof coating, K-Flex thermal insulation, etc.
