GUIDE RINGS (ONK)

GUIDE RINGS ARE DESIGNED: to construct crossings for the pipelines laid in protective casings under roads and railways and other engineering services in all climatic zones at a temperature from minus 40°C to plus 50°C. Guide rings are manufactured only from the materials that ensure design integrity within the whole temperature range.

TECHNICAL CHARACTERISTICS OF GUIDE RINGS

The exact distance between the guide rings is specified by the crossing project based on the allowable pressure on the insulation coating, allowable deflection of the pipeline between the legs and given the additional loads when the service pipe string is dragged through the protective casing (containment).

PROTECTIVE DIELECTRIC RINGS (SPACERS)

PROTECTIVE DIELECTRIC RINGS are designed to protect the surface insulation coating of the steel or polyethylene pipeline dragged through the contain-ment of the underground (submerged) crossings over natural and manmade barriers when constructing new pipelines and repairing the existing pipelines.The monolithic ring segment is fabricated from nylon, the PA-6 synthetic construction material.The rings must meet the specific safety, reliability and time-proof requirements.The SPACER ring design does not include metal parts contacting with the pipeline and thus excludes any possibility of corrosion center formation and pipeline damage.The structure consists of segments easily mounted by bolting directly to the pipeline surface.The number of segments in the ring depends on the pipe diameter and can be normalized for a pipeline with a diameter from 57 mm to 1420 mm.

PROTECTIVECOATINGS FOR PIPES

SLP TECHNICAL CHARACTERISTICS

Polymer rockshield (SLP) is designed to protect the insulated surface of pipelines with a diameter up to 1420 mm inclusively, when the pipelines are laid in rocky and permafrost soils with sharp fractions and in mineral soils with inclusions of land waste, pebbles and unconnected masses of rocks. Two types of the rockshield are manufactured: Type 'O' – standard and Type 'U' – reinforced. The rockshield is the structure manufactured by means of one-way lamination of non-woven synthetic material with polyethylene or other replacing polymer material allowing reliable fixation of the polymer layers (both non-woven and solid) followed by perforation.

The SLP design meets the following principle requirements: 1. Environment friendliness;2. Simplified pipeline lining process;3. Simplified transportation and storage processes;4. No limitation for cathode control.

The SLP rockshield has been protected by the RF patent and granted with the ecological certificate.

NEFTEGAZ profiles are designed to protect the pipeline external surface when the cast iron and/or ferroconcrete weights are installed and to protect the pipeline insulation from mechanical damages when the pipeline is dragged through the casing of the underground/submerged crossing in a complicated territory.

NEFTEGAZ profiles can be used as lining mats under supporting structures and pipeline valves.

NEFTEGAZ profiles considerably decrease the lining time, ensure integrity of the pipeline insulation coating and prolong the service life of the submerged crossing. The profile materials are non-putrescible, suitable for use in aggressive media, environmentally safe, have no harmful impact on the environment and can be used in fresh potable water reservoirs.

NEFTEGAZ profiles are used to construct, reconstruct and repair the pipelines with a diameter from 159 mm to 1420 mm inclusively, in all of the climatic zones at an operation temperature for the steel pipelines from minus 40°С to plus 70°С.

SOIL MODULES (GP 1500)

SOIL MODULES (GP 1500) are cellular structures to be filled with local soils, including silty-clayed or icy soil.They are made of technical textile bands with a design width and various cell dimensions; variations of these parameters allow the required subsoil bearing capacity, depending on dynamic loads.

GP-1500 are used to build the manmade trenches for the pipelines with a diameter of 1420 mm, laid on the daylight surface (GP-1500T), to construct road dirt fill foundations (GP-1500D), and soil conservation structures (GP-1500E). For the said purposes the technical textiles with various design characteris-tics are used, depending on the operation conditions and structure purpose.

THREE-DIMENSIONAL POLYMER GRID (GW)

GEOGRID is an easily mounted 3D polyethylene cellular structure which is put together as a honeycomb structure. The cellular structures are formed from the high-tensile polymer band by thermosonic welding of polyethylene.The polymer band is inert to environment. The standard sections of the GEOGRIDS may consist of several dozen to several thousand cells. The sections are put together with galvanized steel clamps and stapler. The whole structure is fixed inside the soil or on the ground by means of the anchor system and may be additionally reinforced with nylon ropes. The filled cells work as a semi-rigid plate redistributing the load and ensure improved structural strength and longer service life.

GEOGRIDS is a packaged technology to prevent structure displacement, sag and cracking, as well as washing-out and erosion; to control frost boil inevitab-le in the silty soils and; and to drain excess water. GEOGRIDS allow considerable decrease of the bank thickness due to reinforcement and active usage of local construction materials, including wastes and soils.

GEOGRIDS are used to reinforce road foundations, to build road dressing and provide the bearing layer for various sites and foundations placed on soft soils; to protect the water-passing systems, berths and embankments from washing-out; to control soil erosion of the bridge cones and pipeline outlets; to hold the fertile soil on steep slopes; and to build 'green' retaining walls. In addition to improved strength characteristics of the earthwork structures and drainage systems, GEOGRIDS allow naturally smooth and aesthetically perfect lines when managing landscape.

PENOPLEX – EXTRUDED POLYSTYRENE FOAM

PENOPLEX material is increasingly used for thermal insulation of gas and oil pipelines in the Far North.

The pipe insulation allows switching from above-ground and semi-buried pipelining to fully-buried (trenched) pipelining and, therefore, minimizing the pipeline thermal impact on the permafrost soils in the Far North. It helps prevent soil thawing and possible pipeline deformation. It should be mentioned that PENOPLEX reduces in half the earthworks required for sand filling, as well as shortens the construction time and prolongs the life cycle of the gas pipeline.

The high strength characteristics of PENOPLEX ensure reliable protection of pipelines from mechanical damages, including the damage caused by sharp rocks. A typical case is the construction of the Blue Stream Pipeline where the segments made of the extruded polystyrene were used to protect the pipeline in the active tectonic fault areas. The protection preserves the pipeline waterproofing and minimizes effects of a possible earthquake.
