Difference Between 3LPE And 3LPP Coating

Both of 3LPE and 3LPP coating systems provide excellent mechanical as well as corrosion resistant properties for specific requirements. However, there are 12 differences between 3LPE coating and 3LPP coating. Read on to learn more.

Coating Material:

3LPE coating is composed of epoxy resin layer, adhesive layer and polyethylene layer. Whereas 3LPP coating uses polypropylene.

Coating Thickness:

The thickness of 3LPE coating is generally between 1.8mm and 4.0mm, while the thickness of 3LPP coating is between 1.0mm and 4.5mm.

Application:

3PE coating is mainlyapplied for buried pipelines, and 3PP coating isapplied for above-ground pipelines.

Chemical Resistance:

3LPE coating provides better resistance to chemicals, acids and alkalis than 3LPP coating.

Temperature Resistance:

3LPE coatings can withstand temperatures up to 85°C, while 3LPP coatings can withstand temperatures up to 110°C.

UV Resistance:

3LPP coating is more UV resistant than 3LPE coating.

Corrosion Resistance:

Both 3LPE and 3LPP coatings have excellent corrosion resistance.

Installation:

3PE coating is more difficult to install than 3LPP coating because of its thickerlayer.

Cost:

Due to the additional material required, 3PE coatingis usually more expensive than 3LPP coating.

Durability:

Both 3LPE and 3LPP coatings are durable and provide long-term protection for pipes.

Environmental Impact:

Both 3LPE and 3LPP coatings are environmentally friendly and do not contain any harmful substances.

Maintenance:

Both 3LPE and 3LPP coatings require minimal maintenance and can be easily repaired if damaged. However, repairing 3LPE coating may require more effortbecause of its thickness.
