Van Leeuwen supplies welded and seamless carbon steel tubes according to all relevant API, ASTM and EN standards. Temperature, pressure and strength are important factors that determine the choice of tube. Seamless tubes are suitable for high/low temperatures and high pressure, seamless heavy wall tubes for mechanical engineering. Welded tubes are used as line pipe for moderate temperatures and pressures, and for all kinds of constructions.
