SLM® 3.0
Standard pipe made of PE100 RC fitted with a protective PEplus sheath.

SLM® 3.0 is easier to use, easier to weld and is a safe and more reliable pipe system. SLM® 3.0 is a standard pipe made of PE100 RC fitted with a high strength sheath (coat) on the outside of the pipe, providing extra protection against scratches and damage that may occur during pipelaying.

The pipe’s high strength sheath is made of PEplus, with a thickness, in the case of dim 250 mm/SDR17, corresponding to 25% of the pipe’s wall thickness.

Since the sheath is made of polyethylene, it does not need to be removed during butt welding (SLM® 3.0) but can be integrated into the joint, reducing the risk of the sheath being ripped off when performing alternative installation methods such as directional drilling and pipe splitting or when extraction hoods are used.

SLM® 3.0 meets the requirements of PAS 1075 Type 3.

The sheath is welded in the bead – it cannot be ripped off
Since SLM® 3.0 and its sheath are manufactured from the same basic material, i.e. polyethylene, the sheath can be butt welded in the bead. The different layers are then joined together in the weld bead (the sheath merges with the main material), which prevents the sheath from being ripped off during directional drilling or horizontal drawing, etc. when an extraction hood is used. In the case of SLM® DCT, this pipe must be stripped when welding, as it has additional layers of other material.
