We have got DVGW,AWWA,ASTM,SGS certificates and test report, also the sole factory in China passed DVGW, AWWA test. We were approved ISO 9001,ISO 14001 and OHSAS 18001. XUNDA tapes can meet ASTM D1000, DIN EN12068, 30672,AWWA C209, 214 , IGS and other international standards.
Industries that We Serve
l Oil, Gas and Water Transmission pipeline market
l Oil and Gas distribution and utility markets
l New pipeline construction market
l Rehabilitation and Reconditioning market
l Offshore Industry
l Refinery and Petrochemical Plant Industry
l Manufacture of Polyethylene coatings utilizing Butyl based elastomeric adhesives, Polyethylene films and liquid adhesives for Corrosion Protection of steel pipe.
l Provides corrosion protection with the inherent chemistry of Polyethylene and Butyl Adhesive for resistance to water and oxygen penetration. Oxygen and Water are prevented from reaching the metal substrate, which are necessary and sufficient conditions for corrosion.
l Manufacture of conventional and specialty Polyethylene, Polypropylene and Polymeric Alloys and coating systems for pipe corrosion protection.
l Manufactures PE coatings systems for applications for New Pipe Construction and Rehabilitation and Reconditioning
l Approved to ISO 9001 and to other good manufacturing and technical standards and norms governed within the energy and pipeline industry.
l Coating systems that have a broad range of temperature and shear resistance properties to meet the requirements of the pipeline and end-user.

1) Steel pipe pretreatment
1.1 Keeping the pipe external surface clean and dry. Remove the dust,
oil, welding slag, burrs, grease and dirt on pipe surface.
1.2 Pipe surface prepared up-to a level of Sa 2 or 2 ½ or St 2/st by sand blasting.
1.3 After the pre-cleaning operations, the pipe surface not smooth
which may sharp the pipe coating should be burnished , the abrasive
dust attached on the pipe surface should also be cleaned clearly.
1.4 If flash rusting occurs, the surfaces must be re-cleaned by blasting as above.
2) Coating &Wrapping application
2.1 Coating &wrapping application consist of primer application, inner
tape coating ,outer tape coating .
2.2 weather condition
2.2.1 When the wind&sand was strongly, when the sand and dust covered
on the surface of pipe, primer ,tape etc., should not be brushing primer
and wrapping the tape if there is no reliable preventive measures.
2.2.2 When air humidity is greater than 80%,or when the pipe surface is wet from any precipitation, should not be brushing primer and wrapping tape.
3) Brushing primer
3.1 The brushing time should be control within 6 hours between the pipe surface treatment and brush primer. During brush primer, pipe surface should be free from damp and pollution. If the pipe surface rust return, should be re-pre-cleaned.
3.2 The primer should be mixed evenly in the container before brushing.
3.3 The primer should be applied uniformly, without any sags, floods, runs, drips, bare spot and over spray, such as leakage brush, clot, streaming. The primer coat DFT shall not be less than 25-50micron (1-2mils)
3.4 After the primer dried, then wrapping the tape(It usually takes 3to 5 minutes.).
machine applicationapprox. 0,1 litre/m²
hand applicationapprox. 0,2 litre/m²
4) Wrap tape application
4.1 Wrap tape application consists of hand application and machine application.
4.2 The tape applied temperature must be above 5 degrees,the coating construction temperature shall be more than -5 degrees as better .
4.3 The tape shall be spirally applied ,minimum overlap shall not be less than 50%.
4.4 When a new roll of tape started ,the ends shall be located to ensure the continuity of wrap tape using the same method of application.
4.5 Outer tape applied method is the same as above.
Cutbacks shall be a minimum 6inches(150mm) from the ends of each
pipe.The cutbacks may be tapered or straight edge for the total thickness
of the coating.
1. What is the payment terms.
T/T (Telegraphic Transfer) , L/C at sight,Western Union
2. What is the delivery time of the tape.
Usually , 7 days after payment, but it will cost more time when a large order made.
3. Whether the sample is free or not.
The sample will be free with one patch or a small roll . It should paid when you ask for large quantity samples.
