Q-FLEX VELTANIUM GUIDELINES
GENERAL
Do not use dirty/damaged components, pipes, fittings, compression sleeves or seals. ■ Make sure that the connection components are free of prohibited stress during of movement (e.g. from deflection legs). ■ When flat-sealed joints (or similar) are opened, check that the sealing surface is undamaged before reconnecting and insert a new seal if necessary. Use suitable sheeting to protect fittings and compression sleeves against contact with brickwork or with screed, cement, plaster, bonding agents, aggressive media and other materials and substances which can cause corrosion. ■ Protect fittings, pipes and compression sleeves against humidity. ■ Protect fittings, pipes and compression sleeves against dirt, drilling dust, primer and glue, mortar, grease, oil, paint, adhesive/protective primers, solvents, etc. ■ In aggressive environments (e.g. agricultural, encased in concrete, sea water atmosphere, cleaning agents), protect piping and fittings against corrosion adequately and in such a way that they are sealed against vapours (e.g. to aggressive gases, fermentation gases, chloride mediums). ■ Ensure that the employed sealants, cleaning agents, building foams, insulation, protective tape, adhesive tape or thread sealant etc. do not contain any components which cause stress cracking or corrosion, e.g. ammonia, ammonia-bearing, aromatic & oxygenated solvents (e.g. ketone and ether), chlorinated hydrocarbons or chloride which can leach. Veltanium pipe can be bent either by hand or using a bending tool.
BENDING
■ When bending without tools, the min bending radius is 5x the pipe diameter. ■ When bending with a spiral spring, the min bending radius is 3x times the pipe diameter. ■ The minimum bending radius is measured with respect to the centre of the pipe. ■ After bending, ensure that there are no kinks, wrinkles or bulges and installation of Veltanium Plus systems within concrete/screed floors and walls are allowed, provided specific requirements from local installation standards are fulfilled and adequate protection from mechanical damage and chemical damage are provided. Fittings shall be wrapped with suitable tape to avoid direct contact with concrete.
