PROTECTIVE TUBES FOR POST-TENSIONING
Diorit d.o.o. produces protective tubes for post-tensioning from black and galvanized material.
Declaration Data – Product Performance
• subject of declaration of conformity – steel strip pipes for prestressing cables and couplings for these pipes EN 523
• used material – pipes made of steel strip thickness 0.3 – 0.6 mm and width 78 mm, quality according to standards EN 10139/10140 and EN 10346
Steel strip pipes for prestressing cables and couplings for these pipes are used as a guard and guide for prestressing cables in subsequent prestressing of concrete structures.
The quality and characteristics of steel strip pipes are in accordance with EN 524 1-6 regulations. The tube thickness measured during production ranged from 0.3 mm to 0.4 mm corresponding to category 1. Thickness from 0.5 mm to 0.6 mm corresponds to category 2 of the abovementioned standards.
Widely accepted for use in modern construction, and is particularly used for pre-stressing or post-stressing of concrete constructions as building materials, bridges construction, construction of railways and highways, underground facilities, buildings and canals.
Our production in one shift is 4500 m.
Diameter; From Fi 40 mm – Fi 135 mm
TECHNICAL CHARACTERISTICS OF PRODUCTION LINE FOR STEEL STRIP PIPES
CABLES FOR PRE-STRESSED CONCRETE
In most of the post-tensioned and pre-stressed projects, the smooth steel wire is most commonly used as pre-stressed steel. The pre-stressing cables are mainly used to improve the project, but also for nuclear power plants and similar works. Galvanized steel cables are most commonly used in bars of bridges, cables and external pre-stressing. Steel cable coated with epoxy is similar to a galvanized pre-stressed steel wire rope. Cable and wire certificate EN 10138-3 / 10138-1
PREFABRICATED PRE-STRESSING CABLES
Diorit pre-stressing systems offer innovative products and systems for the construction industry with its own production site in Odžak, Bosnia and Herzegovina. In order to avoid complicated requirements for mounting pre-stress cables on construction sites, DIORIT started manufacturing and marketed a pre-assembled system ” select and set “pre-stress cables that can be flexibly used, thus saving time and work of contractor. This will be the first production of prefabricated pre-stress cables in the Balkan region.
