Foreword This standard is based on the accumulated knowledge and experience of manufacturers and users of reciprocating pressors.Theobjective of thispublication is to provide apurchase specification to and gas industry services. The primary purpose of this standard is to establish minimum requirements. Energy conservation is of concernand has bee increasingly important in allaspects of equipment designplicatinandperationhsvativenergcnservingaroacheshouldaggreivl new equipment proposals since the evaluation of purchase options will be based increasingly on total life costs as opposed to acquisition cost alone. Equipment manufacturers in particular are encouraged to suggest altermatives to those specified when of safety or reliability. such approaches achieve improved energy effectiveness and reduced total life costs without the sacrifice Thisstandardrequiresthepurchasertospecifycertaindetails andfeaturesAlthoughitisrecognizedthat that such modifications deletions and amplifications be made by supplementing this standard rather than A bullet (▪) at the begining of a subsection or paragraph indicates that either a decision by or further information from the purchaserisrequired.Furtherinformation should be shown on the data sheets (see example in Annex A) or stated in the quotation request and purchase order.
