Coated steel pipe type:

3PE coated steel pipe, 3PP coated steel pipe, Epoxy coated steel pipe, FBE coated steel pipe, Insulated thermal insulation steel pipe, Coating plastic steel pipe, Polyurethane insulation steel pipe

1. 3PE/ 3PP anti-corrosion and single-layer PE anti-corrosive

1) 3PE/3PP anti-corrosive:

Three-layer structure of PE pipe corrosion: the first layer of powder epoxy ( FBE > 100um ), the second layer of adhesive(AD ) 170～250um, a third layer of polyethylene or polypropylene 2.5～3.7mm. Three materials integration, and with the steel firm to form an excellent coating.

2) Single PE anti-corrosion steel:

single layer PE is the use of anti-corrosion steel curtain coating process ( also known as curtain method ), the steel pipe after rotation frequency heating, steel top is fitted with a polyethylene powder container by pouring dusted steel tube surface polyethylene coating.

2.Epoxy coating

1) Standard: AWWA C210, C205, C203, C213, C215 etc.

2) Materials: Epoxy(according with drinking water standards), polyurethane, Coal-tar , cement-mortar protective etc.

3) Appearance color: White, Black, Blue, Green, Gray etc.

4) Inspection: sand blasting, coating material, dry film thickness, pull-off strength, electric spark testing etc.

Coated steel pipe advantages

Shenlong coating steel pipes are fully automatic coated by machines, with good coating adhesion; the thickness of the graphical layer pipe can be customized; our products are tested by electric spark online to ensure that there are no leaks in the coating; there are also five production lines, with fast delivery time.

Coated steel pipe quality inspection:

1. Our factory has its own "experimental testing center".CNAS Laboratory Accreditation Certificate

2.Control quality strictly.The first pass is the quality inspection on the production line,The second pass is full inspection of the  production quality .

3.We have got internationally recognized certificates, ISO, CE, LR,Philippine certificate,also support third-party testing,as SGS, BV, etc.
