The materials are for construction of a pipeline to transport mono-ethylene glycol.\nYou indicated that Formosa Plastics Corporation is planning to install a number of these pipelines in conjunction with its\nTexas Expansion Project in Point Comfort, Texas.\nWe have reviewed the matter and find that a seam joint factor of 1.00 would be acceptable.\nI trust this adequately responds to your inquiry.\nSincerely,\nOriginal Sign By\nCesar De Leon\nDirector, Regulatory Programs\nOffice of Pipeline Safety\n\n<<<PAGE 2>>>\n\nFormosa Plastics\nP.O. Box 700\n201 Formosa Drive\nPoint Comfort, Texas 77978\nOffice of Pipeline Safety January 13, 1992\n400 7th St., SW\nWashington, D.C. 2059C\nAttention: Mr. George W. Tenley, Director\nReference: Alternate Material Approval\nTitle 49, Part 195, Subpart 106E\nGentlemen:\nFormosa Plastics Corporation is planning to install a number of pipelines in conjunction with its Texas Expansion Project\nin Point Comfort, Texas. One of the pipelines is for the transportation of mono-ethylene glycol.\nFormosa plans on using ASTM A-312 TP304 EFW stainless steel pipe for this line in order to minimize contamination of\nthe mono-ethylene glycol. Fittings and flanges to be used with this pipe are to be made of ASTM A-403 Grade WP304S\nstainless steel and ASTM A-182 F304 stainless steel respectively. The pipe material is not listed in CFR, Title 49, Part 195,\nSubpart 106e and per said part must be approved by the Secretary for use under the regulations.\nThe pipe specified minimum yield strength is 30,000 psi. Formosa has opted to use the allowable yield strength of\n20,000 as listed in ANSI B31.3. Table K-1 in design calculations as well as using a design factor of .5 rather than .72 as\nrequired by the code.\nFormosa requests the approval of the subject material in the construction of these pipelines.\nYour attention to this matter will be greatly appreciated.\nSincerely,\nJack Wu\nFormosa Plastics Corporation","truncated":false,"body_characters":2219}
