3LPE Coated Pipes

ISO 21809 3LPE External Coating Pipe and PE Coated carbon steel pipe supplier in India

What is 3LPE Coating?

3LPE Coated Pipes

 

Pipes typically used in industries such as oil and gas, petrochemicals, textiles, power generation etc have a tremendous amount of stress exerted on them. Often these stresses are reasons for pipes becoming susceptible to cracking and finally failure. The use of 3LPE Coated Pipes is predominant in environments that have applications that are either submerged or buried. Hence, one method of providing improved resistance to corrosion is by coating it with 3LPE.

Often customizable, by manufacturers of 3LPE Coating in India, they are not only preferred for their longevity but they also are able to protect pipes from corrosion at reasonably moderate temperature settings.

3LPE Coating Density

3-Layer Polyethylene Coating or as referred to by its short-form, 3LPE consists of a multilayer setting, wherein the pipes consist of three layers. Layer one consists of a high-performance Fusion Bonded Epoxy or shortened as FBE primer. The layer of primer is followed by another copolymer layer, which acts as an adhesive. And lastly, the final outermost layer consists of polyethylene. The outermost polyethylene layer is what provides the 3LPE Coating Pipe with tough and durable protection.

Thickness of 3LPE Coating on Steel Pipes

  1. minimum 125 µm Epoxy layer thickness
  2. minimum 150 µm copolymer layer thickness
  3. minimum thickness of 1.8 mm to 4.7 mm polyethylene or polypropylene layer

Minimum total layer thickness range

M kg/m Layer thickness in mm
Class A1 Class A2 Class A3 Class B1 Class B2 Class B3 Class C1 Class C2 Class C3
M ≤ 15 1,8 2,1 2,6 1,3 1,8 2,3 1,3 1,7 2,1

Please note: The total required thickness may be reduced for SAW pipes by a maximum of 10% on joint seam.
Class 1 and 2 for medium and light applications (sandy soil).
Class 3 – application in extreme conditions (rocky soil) or underwater.

3LPE Pipe Coating Process

The production of 3LPE Pipe is to conform to standard ISO 21809. This particular standard caters to the natural gas and petroleum industry, wherein the pipes are used for the conveyance of fluid or gas across refineries to sites. The coating process begins by cleaning the pipe to remove any previous residue, followed by the application of the primer via a fusion bonding method. Once the adhesive copolymer layer has coated the primer, the extruded polyethylene layer is applied after which manufacturers cure the pipe in order to seal the ISO 21809 3LPE External Coating.

3 LPE coating acc. To DIN 30670

  • Layer 1: This is a layer is of fusion bonded epoxy used for good corrosion protection.
  • Layer 2: Secon layer is the copolymer adhesive and has good chemical bonding with both layesr of fusion bonded epoxy (FBE) and the top layer polyethylene.
  • Layer 3: This top layer is consists of polyethylene to bond well with each other
