6、abian CHLOR VINYL Project TCC-DSA-ACVP-CMS-00 0 Underground GRP Piping Installation1. PurposeThis method statement is to guide butt joint wrap lamination work of U/G GRP piping system in the Arabian Chlor Vinyl Project.2. ScopeThis Method Statement covers the field lamination joints installation met
7、hod of underground GRP piping. This procedure is applicable to all U/G GRP pipe diameters.Related data of U/G piping GRP part is as following:System description Material class Diameter range Connection MethodW W DGAANA 4”,6”,8”,10”,12”,20 Butt re-sanding of the lamination area shall be required if t
8、he waiting period exceeds two hours. Bonding surfaces must be dry and clean before sanding. Use flapper wheel sanders with a small drilling machine (1700-2000rpm) or emery cloth with a grid of 60. Sanded surfaces must have a dull, fresh finish, not a polished look. Remove any possible dew by slightl
9、y heating the pipe ends by a hot air dryer.Other details see attachment A: Field Butt 3 After the filling of the gap, the putty shall polymerize, without moving and bumping the pieces. 4 Once completed the hardening of the putty, grind the outside of the pipe joint and clean with air blow and clean
10、duster cloth.Note : The gap should not exceed the 5 mm or as per recommended by Pipe manufacturer at any case.10.4 Field Joint Kits PrepareDetails see attachment A: Field Butt Portable water station can be used for eyewash.4、Wear resistant gloves such as: polyvinyl alcohol, butyl rubber, nitrile or
11、neoprene. wear normal work clothing covering arms and legs. Hazard OF MATERIALS:All chemical materials must be used carefully with PPE. RESIN: Cause severe eye and skin irritation. Aspiration of material into the lungs can cause chemical pneumonitis, and other lung injury.ACCELERATOR: Do not breathe
12、 vapours and avoid contact with skin. It can cause lung damage if swallowed and cause cancer. Flammable.CATALYST: Risk of explosion by shock, friction, fire or other sources of ignition, may cause fire, Harmful if swallowed, Caused burns. Keep away from reducing agents, acids, alkalies and heavy met
13、al compounds. Do not mix with peroxide-accelerators or reducing agents. Use only stainless steel 316, PVC, polyethylene or glass-lined equipment.Mat & WOVEN ROVING:SILICAN: Low hazard for usual handling. Repeated exposure may cause skin dryness or cracking. Keep away from heat and sources of ignitio
14、n.STYRENE: “a suspected carcinogen“ and “a suspected toxin to the gastrointestinal tract, kidney, and respiratory system.“ Chronic exposure to styrene leads to tiredness/lethargy, memory deficits, headaches and vertigo.Portable water station and fire extinguisher should be located nearby.Before star
