Fa'ailoga o filo u'amea fa'amea / socket u'u fa'alava ole lalolagi
1. O loʻo i ai le fausaga faʻapitoa, foliga matagofie ma faʻaititia le ala tafe. Faiga faʻavae: BB poʻo le WB;
2. O le faʻamaufaʻailoga faʻamau e faia i le uʻamea uʻamea poʻo le carbide sima. O le faʻatusatusaina o mea faʻamaufaʻailoga e talafeagai ma o le ola tautua e umi;
3. O le valve disc e conical, ma o le valve stem e tuʻuina atu ma faʻamaufaʻailoga faʻafefe, faʻatasi ai ma faʻamaufaʻailoga lelei. O le pito i luga o le alavalo o loʻo faʻafefeteina, lea e lelei le faʻafefeteina ma le faʻafefe. O le faʻapipiʻiina e faʻaaogaina le graphite fetuutuunai, faʻatasi ai ma le faʻamaufaʻailoga faʻalagolago, faʻaogaina le faʻaogaina ma le laʻititi laʻititi ma le tapuni tapuni;
4. E mafai ona filifilia tulaga o paipa eseese ma fa'afeso'ota'i (e pei o le socket welding, butt welding and threaded connection).
