1 CHEMICAL RESISTANCE LIST The resistance of plastic pipe materials to a wide range of chemical is listed in the tables of British Standard Code of practice 312: Part 1. The information provided is designated to be used as a guide and all information must be checked on a project basis. The provided data is based upon room temperature unless otherwise stated. Elevated temperatures will increase the effect of the chemicals upon elastomers. No guarantees can be given in respect of the information printed in this document. Drain Pipes and Fittings The expected behaviour for PVC-U to various chemicals, based upon laboratory tests is summarised below. Additional information based upon practical experiences for the fabricated articles has been given in some instances. Acids Whilst PVC-U is highly resistant to strong acids, some oxidising acids particularly in high concentrates can attack the material. The following is a brief guideline on the use of acids: Hydrochloric acid - Can be used at al concentrations at temperatures up to 60 C Sulphuric acid - At less than 90% concentration has no effect on temperatures up to 60 C, however concentrations of 90 95% should not be carried at temperatures in excess of 50 C Cold Nitric acid- Satisfactory at concentrates up to 50%, hot concentrated acid will attack PVC-U Alkalis Alkalis will not attack PVC-U at all concentrations at temperatures up to 60 C. Halogens Whilst dry chlorine gas will not attack PVC-U at room temperatures, there will be some attack at elevated temperatures if the gas is moist. Both Bromine and fluorine, even in low concentrations, will attack PVC-U at room temperatures. Organic Liquids and Vapours PVC-U is resistant to most alcohols, fats, oils and petrol. Oxidising Agents PVC-U is resistant to all but the most severe oxidising conditions. Hydrogen peroxide at all concentrations has no effect, and even concentrated solutions, oxidising solution or of oxidising salts such as potassium permanganate causes only superficial attack. Reducing Agents Up to temperatures of 60 C these reagents have practically no effect on PVC-U. Water and Dilute There is evidence or failures of PVC-U pipes observed due to contact with water or aqueous solutions of the type, which conforms to the relevant British Standard.
2 General PVC is not suitable for use with: Aromatic and Chlorinated Hydrocarbons Ketones Nitro Compounds Easters and Cyclic Ethers All of these substances will penetrate the PVC and cause considerable swelling and softening of the product. Petrol-based fuels containing benzene can cause swelling to PVC-U products. Penetrating solvents may be harmful to PVC-U, even when dilute. However as they become more dilute their effects noticeably fall off. Very low concentrates such as those present in effluent, can be safely used with PVC-U. It is not advisable to use PVC-U pipes for conveying gas. Careful consideration must be taken on detailed information concerning the constituents, especially any aromatic constituents of the gas.
