Application of this standard ensures that PE coatings provide adequate protection against mechanical, thermal and chemical loads during operation, transportation, storage and installation.
Production controls are to be carried out by the coater or a recognized materials testing body. In case of doubt, the German-language 30760 shall be considered authoritative. They shall be suitable for protecting onshore and offshore pipelines under the required service conditions e. There are 69 din coating suppliers, mainly located in Asia.
Vin is evaluated by assessing the changes in the material through the variation in its melt flow rate MFR.
Furthermore, a twin-blade saw or a suitable cutting device is required to prepare the samples. Generally it is with7 days if the goods are in stock. Stainless Steel Welded Pipe. The voltage should not exceed 25 kV. There are two kinds of procession by winding-wrap and full-coated.
Ageing is evaluated by assessing the changes in the polyethylene through the variation in its melt flow rate MFR. Home About Us We are trusted.

The test pieces shall be subjected to high-voltage continuity testing prior to this test. For testing, the polyethylene layer may be applied without adhesive to make sampling easier.
How to know the Quality Guarantee: The system consists of liquid epoxy base coat, hot-melt adhesive and base from meshed high-density polyethylene.
The peel strength requirements have been adapted to the production methods commonly used today. Coating pipe is the pipe that is by the processing after the corrosion, which can effectively prevent or slow the steel pipe occurs in the course of transport and chemical or electrochemical reaction corrosion phenomena. If there is a spark, mark the defective area.

Proceed to Checkout Continue Shopping. GTS-PE is developed as per unique technology of adhesion directly to main PE coating that provides characteristics not worse than the main coating.
The voltage is to be applied only at the time of measurement.
Experience gained in the transport and laying of pipes and pipelines with polyethylene coatings has shown that a high bond strength is necessary to reduce possible mechanical damage to the pipes. Blast cleaning and any necessary subsequent work shall not result in the reduction of the minimum wall thickness specified in the technical delivery standards for the steel pipe.
The remaining debris should be removed before the coating is coated. Minimum layer thicknesses 306770 given in Table 3 below. The adhesive has been formulated to bond directly to the main coating; epoxy is applied to the steel only.
