The standard length is up to 6 000 mm. materials: PE-HD, PE-80, PE-100, PE natural, PE-EL, PE coloured PP-H (type 1), PP-B (type2), PP-R (type 3) diameter: 1 500 mm, 1 900 mm, 2 500 mm, 3 000 mm, 3 500 mm in a extruder and is helically wound as a band-shaped layer onto a. The standard length is up to 6 000 mm. We produce the appropriate tube or core exactly for your needs and specifications, with diameters up to 635 mm and wall thicknesses of 1 to over 20 mm. We can precisely cut the tubes to any. Die HENZE-Wickeltechnik ist die Basis für viele maßgeschnei-derte Lösungen, sowohl konstruktiv als auch wirtschaftlich. HENZE-Ingenieure liefern hier in Abstimmung mit dem. The spiraling technique consists in coupling a series of adhesive-coated strips, winding them around a mandrel, obtaining a tubular whose electrical, thermal, impregnation and mechanical characteristics are the sum of the ones of each layer. Politubes uses only the best high quality insulating. The RO and NF spiral wound elements are made with the basic industry configuration shown in Figure 1. Spiral wound element configuration The most common product sold is 8-inch diameter, 40-inch long element. General dimensions are shown in Table 1.
