3-Layer Polyethylene (3LPE) Coated Line Pipe

LINKUN can produce3LPE Coated Line Pipe for API 5L PSL 1 & PSL 2 Line Pipes from NPS 2" to NPS 56" (60.3mm - 1422.4mm), welcome to contact us if you have such RFQs.

 

Three Layer Poly Ethylene (3LPE) coating 3LPE coating system is a multilayer coating composed of three functional components: a high-performance fusion-bonded epoxy (FBE), followed by a copolymer adhesive and an outer layer of Medium Density Polyethylene (MDPE) or High-Density Polyethylene (HDPE), which provides protection against external corrosion.

 

The codes and standards for 3LPE Coating are:

DIN 30670-2012, CAN/CSA Z245.21, ISO 21809-1, NFA 49-710, SHELL DEP 31.4030.31-CSPC

 

DIN 30670-2012 Polyethylene Coatings on Steel Pipes and Fittings

ISO 21809-1:2011 Petroleum and natural gas industries -- External coatings for buried or submerged pipelines used in pipeline transportation systems -- Part 1: Polyolefin coatings (3-layer PE and 3-layer PP)

CAN CSA Z245.21 External Polyethylene Coating for Pipe

NFA 49-710 External Three-Layer Polyethylene Based Coating, Application by Extrusion

SHELL DEP 31.40.30.31-CSPC External Polyethylene and Polypropylene Coating for Line Pipe

 

Fusion Bonded Epoxy (FBE): First layer of FBE shall be 150 microns thick.

Adhesive: Second layer of extruded co-polymer adhesive, 200 microns thick.

Polyethylene (MDPE/HDPE): Third layer of extruded polyethylene (MDPE/HDPE) or polypropylene (MDPP/HDPP), 1.6 – 2.95 mm thick.

Application of Coating:

Surface preparation of pipe by sandblast cleaning (SSPC-SP10/NACE No.2/ISO 8501-1 Sa 2 1/2/SIS 05 59 00)

Subsequent to pipe heating fusion epoxy powder shall be applied

Extruded adhesive shall be applied over the pipe.

Finally extruded polyethylene (MDPE or HDPE) layer shall be applied over the adhesive layer.

Total coating thickness is generally < 3.0 mm for pipe dia < 24" and 3.3 mm for pipe dia 32" & above)
