RESPONSIBILITIES: 4.1
The overall responsibility for all physical activities are lies with the Ocean rubber factory supervisor who will be ed by hot vulcanizing technicians, QA/QC and safety personnel at shop, to ensure that the activities incorporated in this method statement & all quality aspects are followed.
4.2
Ocean rubber factory QA/QC Engineer and Inspector is responsible for monitoring of all physical activities during lining and vulcanizing
4.3
Ocean rubber factory and ABC QA/QC Engineers and QA/QC Inspectors are responsible to all QA/QC related documents and implementation.
4.4
Ocean rubber factory hot vulcanizing technicians will be responsible for rubber lining.
4.5
Ocean rubber factory safety officer shall ensure that rubber lining works and related activities re undertaken in accordance with the company safety procedure, and that all necessary precaution is being implemented.
MATERIAL TYPES AND STORAGE: 5.1
RUBBER Rubber material used for lining shall be Chloroprene rubber (Neoprene). The thickness of rubber lining shall be at least 3mm.Keep rubber material in cool dry place. Rubber lined process equipment shall not be stored at ambient temperatures below−20 °C (-4 °F) for hard rubber. Avoid the of rubber with any dust oil etc.
5.2
Adhesive material REMA Tip Top Heating solution (HS) T4, Tip Top cleaning solvent-R4 shall be used as adhesive materials. Store in cool and dry place. Do not store in aluminum, zinc, aluminum alloys and plastic container. Prevent water or moisture from entering container.

METHOD STATEMENT FOR RUBBER LINING TO SPOOL
6.1
The steel surface to be lined shall be smooth, clean and free from pitting, cavities, porosity, scale or other deposits and shall be blast-cleaned to a surface finish corresponding to at least Sa 2.5.
6.2
Directly after blast cleaning of the steel substrate, the grit, dust, etc., shall be removed and a layer of adhesive primer with a dry film thickness in the range of 30 μm(1.2 mil)to 50 μm (2 mil) shall be applied.
6.3
After sufficient evaporation of the solvent (but not longer than 100 h), the precut, non-vulcanized rubber sheets are applied. Care shall be taken to position the sheets accurately without entrapment of air.
6.4
After application rubber lining, the spools shall be shifted into heating chamber and keep for curing at a temperature of 140 °C to 160 °C at 4 – 6 Bar (284 °F to 320 °F) for 6 to 7 hours.
6.5
A sample piece shall be prepared and lined on a plate parallel to the spools lining activities as per the steps 6.1 to 6.4 above, for conducting adhesion test.
6.6
After vulcanization of the rubber lining, the steel parts shall be painted externally in accordance with DEP 30.48.00.31-Gen. (This activity not included in this scope).
7.0 INSPECTION: 7.1 100% Visual examination shall be carried out before and after hydro test to ensure that there are no trapped air pockets & workmanship is generally good. 7.2 100% Holiday testing shall be carried-out before and after hydro test at a voltage of 6(1+Thickness of lining)Kv at a maximum of 30Kv.

7.3 Thickness measurement shall be carried out on minimum 3 spots/ piece or square meter 7.4 Hardness testing shall be carried out on minimum 3 spots/ piece using shore-A hardness meter. 7.5 Adhesion test of sample piece shall be conducted and shall reach
minimum of 5 MPa (725PSi) for temperature up to 60°C 7.6 Hydrostatic pressure test at test pressure at given in appropriate design code for 1 Hour
8.0 SAFETY PRECAUTION: 8.1 The chemical components required for rubber lining repair/patch activities present certain safety health hazards if not handled well. 8.2 Adhesives (REMA TIP TOP heating solution T-4, TIP TOP Cleaning solvent -R4):- Adhesives used for vulcanizing activities may be irritating to eye and skin, inhalation will effect on central nervous system. It is flammable liquid. Highly flammable, irritating to eye and skin, harmful 8.3 Work in adequate ventilation. Wear dust/vapour mask while working at site. 8.4 All crew shall use protective/safety glasses and rubber gloves. 8.5 All materials and chemicals shall be away from heat source, sparks and open flames. 8.6 First aid for Inhalation: move victim to fresh air. 8.7 First Aid for Eyes: Flush exposed eyes with large amount of water. In case of severity, immediately obtain medical aid from nearest hospital. 8.8 First Aid for Skin: Wash with soap using enough volume of water. 9.0 ATTACHMENTS: 9.1 Technical datasheet of Neoprene rubber.
