DIN coated steel pipe with Polyethylene coatings
Then, attach the additional weight to the indenter and, after 24 h, read the depth of indentation indicated on the penetrometer scale. The present standard specifies requirements for coatings that are applied to longitudinally or spirally welded or seamless steel pipes and fittings used for the construction of pipelines for conveying liquids or gases.
The previous edition of DIN was published in and could not be revised for a long time because work was being carried out on the European standards project EN If the document is revised sin amended, you will be notified 36070 email.
For extruded coatings a differentiation is made between sleeve extrusion and sheet extrusion. The test pieces shall be subjected to high-voltage continuity testing prior to this test. Contact Us Sales Team Network. Gold Plus Supplier The supplier supports Trade Assurance — A free service that protects your orders from payment to delivery. The present standard specifies requirements for coatings that are applied to longitudinally or spirally welded or seamless steel pipes and fittings used for the construction of pipelines for conveying liquids or gases.
Di 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.
In case of doubt, the German-language original shall fin considered authoritative. The sample shall be rin in the cold state. We will attach some relevant photos via email so show our factory, machine and products for you. This standard is also available to be included in Standards Subscriptions.

You may delete a document from your Alert Profile at any time. Set the zero value within 5 s. The peak occurring further along the curve characterises the uncured portion of the material.
Prior to coating application, the metal surface of the steel pipe shall be free of all contaminants and deleterious matter such as dirt, oil, grease, weld beads, etc. Minimum layer thicknesses are given in Table 3 below. The supplier supports Trade Assurance — A free service that protects your orders from payment to delivery.
The option of agreeing on design temperatures for different types of coating, and of agreeing on a special, greater coating thickness have been maintained here.
Information as to whether specimens were compression-moulded, sintered or extruded is also required. In system testing fin required material properties and functional requirements on the coating components as in this standard are determined and documented.
Heat-shrinkable sleeve “CANUSA GTS-PE 3L”
The final evaluation shall be carried out after the ageing time specified above for each type of coating. This data relates to the raw materials and can differ from the values for the applied coating. Polyethylene coatings of steel pipes adn fittings. The present edition of DIN not only covers fields of application that are not dealt with in DIN EN ISO and DIN ENit also takes into consideration the current state of the art, not only as regards sin tests and test frequencies specified here for the first time, but also as regards various product requirements.
Care shall be taken that coating samples are free of adhesives. Divide the ein into eight dun. Ageing is evaluated by assessing the changes in the material through the variation in its melt flow rate MFR. Subscription pricing is determined by: For submerged arc welded pipes, an additional four thickness measurements shall be taken on the weld area.
The face of the weight used is part of a hemispherical head with a diameter of 25 mm. 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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The saponification of adhesive components, and thus stress crack formation due to the effects of wetting agents, are not possible when an epoxy resin primer and adhesive copolymers are used in a threelayer coating system.
Similar systems – wrapping bands from RMPE and PE — require higher temperatures and number of equipment for installation. The standard specifies requirements and test methods of factory-applied and melted extruded polyethylene coatings of buried steel pipes and fittings.
The differences between sintered and extruded by sleeve extrusion or sheet extrusion coatings have been taking into consideration.
The distance between two impacts should be at least 30 mm. Other design temperatures may be agreed between the purchaser and the coater. Add to Alert PDF. DIN EN ISO specifies the international standard requirements for the three tier extruded polyethylene and polypropylene based coatings for oil and gas pipeline transportation systems.
Other documents may be agreed. What is your terms of payment 9 A: Production control is assured by the coater. The sample shall not have any PE adhesive residues.
