The Insulation vas composed of a weatherproofed asbestos cloth wrapper lined with a filler of amoslte, chrysotils and rayon fibers woven together with asbestos yarn into slivers. Eleven of the slivers formed the filler for the two inch pipe sise. The wrapper or jacket was provided at each end of the longitudinal joint with a flap to close the joint against ingress of water. A flap or overlap was also provided circumferentially for water protection. The covering was held on the pipe by copper wire laced across the hooks pro vided on the covering.

It vas reported that the coating tended to wash off whan subjected to the severe action of steam, water and cl canine compounds as used for washing locomotives. Research vas asked to supply samples of an improved product. As covered by this report, laboratory tests were conducted on factory-made material versus a heavily coated eeaple prepared In the laboratory. The tests consisted of subjecting the test specimens to a jet of steam for approximately 50 hours with intermittent immersions in kerosene and Oakite solutions. Bo pronounced veer of the coating could be noted after the testa. Since the severe tests described above did not disclose any lack of resistance to steam, oil or caustic in our standard product, it 1b believed that the field failure on the Union Pacific vas (a) the result of some service condition not reported in correspondence, or (b) due to an off-standard lot of tubing. Work on this project baa been discontinued pending clarification of the problem. R. 1. Halstead lvp This report consists of Stannary (l) anr' Test Data (2). C. F. Rassveiler, GH A. Cromwell, GH E. R.

Bont of our Raw Tori office visited the Textile Section of the Research laboratory mainly to discuss, with Messrs* I* Barnett and the writer, the possibilities of changing the present construction of Ihsutape so that present royalties, or licensing fees, paid to Union Asbestos Company can be eliminated* Ihe following subjects were discussed: A* Ihsutane 1* Inner filler (a) Possibility of braiding and knitting this filler (b) Possibility of waterproofing the filler with Neoprene, Pezmal, etc* 2* Outer ShAwfcMng (a) Possibility of braiding or knitting* (b) Possibility of treating the complete outer surface (front and back when flat) rather than one side (front when flat), as is now done* Samples of filler and sheathing treated various ways were Inspected, and it was suggested to Mr* Hunt that if further research work was needed a request be forwarded for whatever assistance is needed* B* Redesign of Twisters In Cwdin Plant In order to Increase production, reduce waste, and improve quality the Canadian plant would like to Increase the size of the yam package on the twister spindle* We are of the belief that these twisters were originally at our Waukegan Plant and are 30 to 40 years old, or more* Apparently the yam is wound directly on the spindle of the twister and a filling wind (cam) is used* It was suggested that Mr* Hunt forward us the following information and we would get additional information from the machine builder and present change over suggestions to him In a letter or report: 1* Make of machine 2* Serial No* and date of installation, If possible (generally found on mall name plate) 3* Diameter of ring 4* Gauge of machine (distance between spindles) 5* Sample of present full package made Memorandum Ho.

Boring, and lara This subject was discussed In a general way* and It vas finally agreed that we would experiment with the package dyeing of roving, either 8 or 10 cat, whan possible to do so. We will notify Hr. Hunt of the results. D. frrlon (210 denier) for Cora Strenri 1* kmh*tr>n ftprtng mnA, lam Hylon (210 denier) strand is now used to reinforce certain rowings T^ yarns, at the Canadian Plant, but the nylon is of a slippery nature, thus, csnalng the outer roving to slide resulting In skips or bunches on the end product of customers, it present it is necessary to eomblne a ootton strand with the nylon to reduce or eliminate theslipping of the outer covering (roving). This Increases the cost of production. The Masvllle Textile Plant are Investigating the use of nylon as a core strand and have run Into the slippery characteristics of nylon. 1. It may be possible to neutralize the sllpperlness of the nylon by adding, at Increased cost, a twisting process where some of the filaments are broken by stretching or by means of emery or carborundum In the thread eye. The later appears most practical. 2. It was suggested that the use of Syton (Monsanto), or Ludox (DuPont) be Investigated as a means of neutralizing the slippery characteristics of the nylon; either by spraying or strand vetting. These are collodlal silica products. ManvUle Plant plans to experiment with this and the results will be forwarded. E. Slain* nt Warp Yarns to Improve Weaving This subject vas discussed In a general way. There is a possibility that sizing of warp yarns will improve weaving. We have had that belief for same time but to really experiment or Investigate this the purchase of si-wwMwg equipment would be necessary. It is hoped that between our present scheduled experiments and Investigations we can carry on Inexpensive Investigations along this line. Avp eex K. v. Huffina, GH TT. C. dine, (2 G. P. Bunt, GH S.

SUMMARY The Transportation Department requested the development of a product suitable for Insulating various small sizes of piping on railroad rolling stock by spiral wrapping, which could replace the Ihsutape presently manufactured for us by Union Asbestos and Rubber Company, and which could be eold competitively with that product. The Textile Section of Research designed a tape having an asbestos fabric jacket partially coated with a rubber compound and filled with a Thermoflex pad. Manville Industrial Products Plant developed and modified the product to adapt it to a satisfactory production basis and within the allowable oost as contained in SPR No. IN-87. Results of tests on samples of the tape made at Manville Plant indioate that this new product has far greater heat resistance than Insutape as made by Union Asbestos and by Canadian J.M. on the basis of retention of filler during exposure at service temperatures as well as at accelerated heat exposure. In addition, the new tape has a flap which is used for overlapping adjacent coils when wrapped on pipe. This should improve the weather resistance of the product by preventing the possible passage of water between coils. APPROVED REPORTED BI Irvin Barnett THIS REPORT OUNSISTS OF I. II. III. IV.
