These Standards have been designed to rill re quirements of the Engineering,Purchasing and Pipe Shop Departments Of the Coapany and slallar requirements of outside Contractors engaged in Coapany work. 1 DESIGN and BILLING NOTES Designers shall pay particular attention to the various thick* nesses for the different pipe sizes to Insure providing neces sary clearance between parallel piping,or piping close to walls, ceilings or equipment* Designers shall specify Size and quantity of Insulation requir ed for blocking across flanged pipe fittings and valves,*eld end valves,equipment nozzles and other equipment flanges which are to be insulated. These lteas are often overlooked And are not available unless they are billed, listed and purchased for respective applIcstlons. Bills of Material shall list the following: a. Kind,type,size and quantity of Insulation proper* b. Kind,type,sire and quantity of insulation fir blocking In flanged fittings,valves,nozzles,etc* c. Quantity of weatherproof felt If required* d. Quantity of galvanized sheet metal If required. e. Sundry materials shall be billed As "One ldt of Sun dries consisting of mini in,paste,staples,asphalt aastle ...etc." Refer to Sundries, IN-209* 2. JOB PREPARATORY WORK a. All surfaces shall be clean before applying insulation. All loose scale,dtrt,etc.,shall he removed, wire brushlhg where necessary. b. Vessels for hot Insulation do not require sand blasting and painting unless In badly rusted condition. e. Vessels for cold Insulation shall be sandblasted and palm ed one prime ccat in the shop and a second coat of the same in the field. d. All piping and equipment shall be tight before JnsiilitlOn Is applied. Testing for tightness, particularly 1h hew construc tion, should precede application wlnrevcr practical and possible. e. piping and equipment shall not he covered Ih wet or frost ed condition. This shall be especially adhered to In cold Insulation work. 3* INSULATION JOINTS All Insulation joints shall lie tnie,eveh and firmly butted together. StyroToam and cork Joints shall be sealed and #aH*.Absolutely tight against entry of moisture. N.l'.P. CKtCKIfcitwu m: V*r THE DOW CHEMICAL COMPANY.

Included here are branch or connecting lines froa dis tribution wains to operating equlpwent. b. Include also process piping and process equlpwent in general* However, operating conditions way dictate the type, Irind and thickness of insulation in order to weet process requlrewents. 3.
