An inhibitor being introduced into the batch or through raw material analysis control formulation coverage 2 Any use of an OD or ID coating spray or otherwise applied is acceptable as long as Desting or clearance tolerances are not adversely affected B. An Insulation contributory to stress corrosion can be secured on a range approach by 1. Using a special batch which may possibly compromise other physical properties and be somewhat higher in coat products 2. Such and are to be manufactured on a made- order basis by the plant 3. Coating the OD and ID surfaces is permissible to augment resistance obtained from special batch provided present dimensional stability and clearances are maintained 76 DISCUSSION continued 00559 C. Corrosion protected and product must be accepted industry 1. By use of DuPont Method in tasting 8. OCF is to conduct test for six months and result must show no corrosion attack using the accelerated method involving moisture application This is the only basis on which DuPont will accept result .bo OCF is to guarantee that all future production will be of the same composition batch formulation as on those specimens on which test results were secured for corrosion attack on stainless steel Do Present OCF agreement with Pont on testing is 1 OCF tests bust show a corrosion and product at the end of six months under the accelerated method of testing at General Testing Lab in Granville . 2. Samples are to be submitted to DuPont from same group as OCF secured the six months corrosionfree test results 3 DuPont is to further test for three additional conths the samples turned over to them If at the end of nine months there is not any evidence of stress corrosion the products from that tested composition will be acceptable to Dupont for application on stainless steel pipe or vessels E. Any future formulation change from the one DuPont has accepted through test results and so accredited for their corrosion resistance use will have to go through the same test procedure with the same elapsed time as the original one before that and product will be acceptable I. 3 Absorptivity Absorptivity | , . A. William Turner of Carbide has stated the need for a high temperature heat insulation with a low absorptivity characteristic coupled with high resistance to impact and flexural strength 1. Would eliminate damage to insulation from moisture absorption when stored unprotected out of doors and exposed to inclement weather This particularly applies to conditions at construction altes 77 DISCUSSION continued continued 00339 00339 2 Would reduce fire hazards which are now presant because all calcium silicates act as a wick for any liquids which escape through a leaking pipe if these are of a flammable or inflammable nature 3 Would eliminate corrosion mostly from rust attack on structural steel members where they are not waterproofed with a coating before insulation is applied for fireproofing purposes on vessels exposed to outdoor weather conditions Properties - Thermal Properties A. Thermal conductivity at 0.50 Btu @ 500 mean temperature to be maintained and improved on K10 light density formulations Disensional Stability I. - Stability Stability Stability A. Dimensional Dimensional stability at 1200 for twenty hours at 1.48 maximum shrinkage shall be maintained or decreased decreased for K10 light density material B. Dimensional Dimensional stability at 1800 for twenty hours at 2.0 maximum shrinkage shall be maintained or decreased for K17 or K20 light density insulations Physical Dimensions Holded Physical of Pipe Insulation Variances in physical dimensions of molded pipe are to . be reduced or eliminated 1. Some dimensional variances are caused by tolerances set up during early bold manufacture years ago These variances will be encountered until mold equipment la replaced 2 Floating cores are a cause of some true dimensions in matching half section or full sections one to another ~@. Work in General Engineering is under way to design a mechanical device for eliminating off physical dimensions from this source using pouring technique of cores in or cores out 3. Pouring techniques can permit strengthening fibers to come between spacers and cores causing an off matching diversion between half section and half saction These variances have been and can be liminated to remove this cource of non matching OD surfaces at joints 78 Amen 4 da a& y aaa ~ rete fa faaere) Y - ~~ FIBERGLAS FIBERGLASFIBERGLAS FIBERGLAS COMPANY CORRESPONDENCE ' 0.

He does glass yarn for consideration on this five per cent coated glass Sales has two poinntasmely 1 that present scrap screening coated glass fiber fiber inclusion increase the possibility of stress corrosion Mr. Boynton would greatly Lotz's test of four weeks @ 80 per cent cracking Recent refers to William to have a costing avail- conversations with Dr. Marzocchi disclose he expects if not around November 1 that will be as low as able for trial purposes chloride on end product thus equaling or giving a botter lower in soluble attack rate on stainless steel than present production other stress corrosion point reflects a concern that the plant's production cent coated 2 Mr. Boynton'e when the five per and throughput may be lowered efficiencies fibers are introduced into the batch This is not necessarily BO and the plant personnal glass and the planning and follow through by everyone themselves should be pointed to prevent such an occurrence did not state but we are sure he implied by the Mr. Boynton further cent vinyl costed glass approval given to the idnecnosirtpyoraKtaiyolno obfatfcihve tphaetr both he and Mr. Vyverberg fibers in 10 light to the development of a special batch that is non- were also in agreement to the corrosion of stainless steel This would be the insulation so called that is contributory Their overall desire to to have an short range approach to stress corrosion universally used but is contributory We outline feel that that Boynton we have drawn up as well as Mr. Vyverberg will If they have any differences and will be soon adjusted to be in agreement endorse the these can It is emphasized also that we should vigorously to completion that have been set up namely pursue the projects at Anderson set up 2 Textile Engineering and Production groups of coated yard necessary to produce 60 - 70,000 the equipment method for single strand coating either using at the beginning a This must be an operative production 75 or 150's waste if available to maintain the coated unit as far as they are concerned in order formulation By uninterrupted in Berlin's 10 light density yarn ready it is reasonable to assume the time they have this operationtested Dr. Marzocchi's low chloride that we will have plant process costing on sufficient yarn to necertain end results will have to have designed 2.
