MONO SPECJAL armoured pipe:

• a pressure pipe is protected against damage during transportation, storing, handling and laying of a pipeline in both trenchless technology and excavation technology
• both rapid and slow crack propagation phenomena are almost completely eliminated
• scratches, cuts or point loads are not directly transmitted to the internal pressure pipe
• high resistance to scratching, cutting and load points
• high stress crack resistance (FNCT, ACT)
• the pipes are in accordance with the PAS 1075 requirements
• no need to use sand bedding and haunching while laying the pipes in subsoils
• usage of traditional methods of joining: butt-welding, electrofusion welding and compression fittings
• usage of typical fittings for butt-welding and electrofusion welding
• possibility of producing segmented fittings
• possibility of connecting with other pipes and with polyethylene fittings

SPECJAL and DUO SPECJAL armoured pipe:

• the inner pipe is additionally protected against damage during transportation, storing, handling and laying of a pipeline in both trenchless technology and excavation technology
• double protection against rapid and slow crack propagation
• in SPECJAL and DUO SPECJAL pipes scratches, cuts or point loads are not directly transmitted to the internal pressure pipe
• extra resistance to scratching, cutting and load points
• extra stress crack resistance (FNCT, ACT)
• extra resistance due to the protection armor – excellent long term mechanical properties (CLT)
• the pipes are in accordance with the PAS 1075 requirements
• no need to use sand bedding and haunching while laying the pipes in subsoils
• possibility of butt-welding (without removal of the protection armour)
• possibility of electrofusion welding and using compression fittings (after previous removal of the protection armour)
• possibility of using typical fittings for butt-welding and electrofusion welding
• possibility of producing segmented fittings using SPECJAL and DUO SPECJAL pipes
• both the inner pipe and the protection armour are fully weldable
• possibility of joining with other pipes and fittings made of polyethylene
• possibility of using a detectable tape (made of steel, copper or aluminium) between the protection armour and the inner pipe what enables localization of the pipeline after horizontal directional drilling, crack-lining or other method of lining has been carried out
