Buyer should agree to any deviation from material use. To this end the polyethylene coating can be applied without a PE adhesive layer to make sampling easier.
The supplier supports Trade Assurance — A free service that protects your orders from payment to delivery. In each case three measurements shall be taken. Looking forward to your favourable inquiry!
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 dih liquids or gases. Any deviating requirements of the purchaser regarding the materials to be used shall be subject to agreement.
The minimum layer thickness is ? Subscription pricing is determined by: For single-layer sintered polyethylene coatings, it is difficult 306770 achieve the required peel strength without suitable surface preparation, and so the cathodic disbondment test is not required for single-layer sintered polyethylene coatings.
A noticeable air gap will distort the result.
NOTE Using a suitable cutting tool, cut out and then remove a square area of the coating the size of the sealed cylinder. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
Contact Us Sales Team Network. Add to Alert PDF. After it has cooled, the appearance and continuity of the coating system shall be visually assessed along the entire pipe length. Then, centre the electroyte cell with the electrodes around the hole.

fin The loss of adhesion is recognizable as a nearly circular area and is to be determined as follows. Determination of gel time of thermosetting coating powders at a given temperature DIN EN ISOPreparation of steel substrates before application of paints and related products — Visual assessment of surface cleanliness — Part 1: Alternative provisions for repairs may be agreed. PSL 2 WT 3.
Production controls are to 30607 carried out by the coater or a recognized materials testing body. The immersed test surface should be at least 0,03 m?. GTS-PE is developed as per unique technology of adhesion directly to main PE coating that provides characteristics not worse than the main coating. 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.
Forced curing method Approved Canusa method of forced curing of epoxy base coat on steel allows preliminary check of joint before sleeve application. The peel strength requirements vary depending on whether the adhesive was applied as a powder or was extruded. During transportation, measures shall be taken to prevent damage to the steel pipes and fittings or to the coating.
Three layer polyethylene / Anticorrosive coatings / Offer / Izostal S.A.
Furthermore, a penetrometer with a dial gauge having an accuracy of 0,1 mm is needed. In system testing the required material properties and functional 306770 on the coating components as in this standard are determined and documented.
Using a suitable tool, chip off a sufficiently large area of the coating around the drilled hole. You can ensure product safety by selecting from certified suppliers, including 31 with ISO, 14 with Other, and 4 with ISO certification. The same applies to the relevant extrusion line parameters.
Heat-shrinkable sleeve “CANUSA GTS-PE 3L”
Furthermore, a direct current supply having a minimum output voltage of 50 V and an ammeter and a voltmeter are necessary. Proceed to Checkout Continue Shopping. Please first verify your email before subscribing to alerts.
B PSL1 seamless steel pipe. For extruded coatings a differentiation is made between sleeve extrusion and sheet extrusion. A differentiation is made between production control and system testing.
This data relates to the raw materials and can differ from the values for the applied coating.
They shall be suitable for protecting onshore and offshore pipelines under the required service conditions e. About product and suppliers: Stainless Steel Seamless Pipe. The test of the degree of cure of the epoxy resin coating by means of DSC measurement is also 300670, as is the cathodic disbondment test, which is frequently required at international level.
