Packaging & Delivery
standard export carton for PIPE WRAPPING TAPE FOR UNDER GROUND PIPE FOR ANTI CORROSION PURPOSE
PIPE WRAPPING TAPE FOR UNDER GROUND PIPE FOR ANTI CORROSION PURPOSE consists of primer +black inner tape +white outer tape
XUNDA T 200 series outer wrap tape is produced through extruding the composite anticorrosion materials. The adhesive layer is attached to the polyethylene film backing through thermal compounding. The anticorrosion system is comprised of primer, anticorrosion adhesive tape (inner tape) and protective tape (outer tape)
The outer wrap tape always called Mechanical tape,outer tape,outer wrap tape,outer layer tape,outerwrap tape.The backing is more thicker with a few adhesive .The color is White.
The XUNDA-T200 series is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water underground or overhead pipelines. The outer-layer tape backing shall be compounded so that it will be resistance to outdoor weathering.
It also provide protection to the inner layer from damage during storage, transportation, installation and throughout the lifetime of the pipeline
Featuring excellent insulativity
Resistant to UV
Easily applied with no special equipment
Compatible with common pipe coatings
Excellent resistance to cathodic disbonding
Good Mechanical protective effect
High mechanical strength
Small water absorption
Long service lifetime
Good resistance to impact and ageing
The outer wrap tape can be used in the construction conveniently with safety and no pollution
The outer wrap tape is widely applied in many areas with high efficiency.
High density polyethylene as backing layer and butyl rubber,synthetic resins as adhesive layer
The coating materials shall be stored in a clean, dry area
All materials shall be delivered to the jobsite in sealed and labelled containers and
shall be stored in a location that is protected from the elements, well ventilated and freefrom excessive heat, open flame, or other sources of ignition. Coating materials subjectto freeze shall be stored in a heated area.
The materials storerooms shall be appropriately ventilated and shall comply with applicable lawprovisions on safety and fire prevention.
Tape stored at jobsites or material yards shall be kept dry and under cover and never exposedto direct sunlight. Rolls shall not be stacked more than four (4) tiers high and never directly onthe ground or on irregular surfaces. The cores of stored tape rolls shall be vertical. Rolls shallnot be thrown or dropped. Hooks or other sharp handling devices shall not be used. Tape shallnot be stored in contact with protrusions capable of puncturing the material. Rolls or equipmentshall not be piled on top of or against stored tape.
How to install pipeline tapes?
The inner-layer tape shall be applied directly onto the prepared pipe surface,
Wrap tape application consists of hand application and machine application.
The tape applied temperature must be above 5 degrees, the coating construction temperature shall be
more than -5 degrees as better.
The tape shall be spirally applied ,minimum overlap shall not be less than 50%.When applied to
spirally welded pipe , the direction of the tape spiral shall be generally parallel to the weld spiral.
The minimum overlap shall not be less than 25 mm.
4)When a new row of tape is started, the ends shall be overlapped at least 150 mm measured circumference.
