Co., Los Angeles, C a lif. Dear S ir : Some few years ago^w e had the p r iv ile g e of quoting p ric e s on pipe fo r some paroposed water pipe lin e near Las Vegas fo r your Company f The w r ite r p erson a lly c a lle d at your o f f i c e and learned th at you had decided to i n s t a l l re in fo rc e d concrVte pj^ e. Since the maximum pressure in the lin e was something above 100 fo o t head, we wondered whether you would have tro u b le a f t e r some usage. We have met w ith poor success in th e use o f concrete pipe fo r pressures exceeding 50 fo o t head. I f you can take the tim e to inform us what your experience has been w ith the concrete pipe in s ta lle d a few years ago in Nevada; a lso we should be glad to have you sta te under what pressure the pipe has been servin g and what character o f jo in t s , i f i t were jo in te d p ip e. Thanking you in advance, we remain, Yours t r u ly , THE D.C President. DCD M
