description Foreliggende oppfinnelse vedrører en fremgangsmåte for sammenføyning av polymerbelagte stålrør som omfatter trinnene med å - tilveiebringe polymerbelagte rørsegmenter med en ubelagt lengde i begge ender av segmentene; - sammensveise de polymerbelagte rørsegmentene; - påføre en herdbar polymer (A) på den ubelagte lengden av de sveisede rørsegmentene for å danne et første belegglag, og -påføre en polymersammensetning (B) på det første belegglaget for å danne et toppbelegglag med en tykkelse på 0,5 til 10 mm, hvori polymersammensetningen (B) har en smelteindeks MFR2 på 1,0 til 6,0 g/10 min, bestemt i henhold til ISO 1133 ved en temperatur på 190 °C under en belastning på 2,16 kg, og inkluderer et basisresin omfattende (B-1) et ikke-elastomert polyetylen i en mengde på 60 til 85 vekt% av den totale polymersammensetningen som produseres i en prosess ved anvendelse av en enkelt-sete-katalysator, og (B-2) en elastomer som omfatter en kopolymer av etylen og minst én polar komonomer, hvori komponent (B-1) eller komponentene (B-1) og (B-2) er blitt podet med et surt podingsmiddel og anvendelsen av polymersammensetningen (B) som toppbelegglag med en tykkelse på 0,5 til 10 mm ved belegging av belagte stålrørfeltskjøter, en fremgangsmåte for belegging av et stålrør og anvendelse av polymersammen- setning (B) for beleggingen av stålrørfeltskjøter eller stålrør. The present invention relates to a method of joining polymer coated steel pipes comprising the steps of - providing polymer coated pipe segments with an uncoated length on both ends of the segments; - welding the polymer coated pipe segments together; - applying a curable polymer (A) onto the uncoated length of the welded pipe segments to form an first coating layer; and - applying a polymer composition (B) onto the first coating layer to form a topcoat layer with a thickness of 0.5 to 10 mm, wherein the polymer composition (B) has a melt flow rate MFR 2 of 1.0 to 6.0 g/10 min, determined according to ISO 1133 at a temperature of 190°C under a load of 2.16 kg, and includes a base resin comprising (B-1) a non-elastomeric polyethylene in an amount of 60 to 85 wt% of the total polymer composition being produced in a process using a single-site catalyst, and (B-2) an elastomer comprising a copolymer of ethylene and at least one polar comonomer, wherein component (B-1) or components (B-1) and (B-2) have been grafted with an acid grafting agent and the use of polymer composition (B) as topcoat layer with a thickness of
