O le Botop Steel o le kamupani gaosi oloa ma le fa'atau oloa ta'imua i paipa u'amea ma paipa i Saina, matou te teuina ma sapalai paipa u'amea kaponi lapotopoto e leai ni paipa mo fa'aoga vai ma suau'u i le tele e amata mai le 10 OD i le 660 OD i le mafiafia e amata mai le 1mm i le 100mm. Matou te gaosia paipa u'amea kaponi LSAW e tusa ai ma tulaga fa'avaomalo e pei o le ASTM, API & DIN. E silia ma le 8000 tone paipa laina leai ni paipa o lo'o iai i masina ta'itasi, e masani lava ona mafai ona matou tu'uina atu oloa i le taimi lava lena. Peita'i, i tulaga fa'apitoa, afai e iai ni paipa opaipa u'amea kaponie le o maua e mafai ona matou tilivaina oloa i se taimi pu'upu'u e ala i punaoa fa'alotoifale po'o oloa mai fafo
O a matou umapaipa u'ameama o oloa paipa e tuʻuina atu faʻatasi ma tusi faʻamaonia faʻapitoa 3.1, e tusa ai ma le EN 10204. E mafai ona malilie i le faʻamaoniga e tusa ai ma le 3.2 i le taimi e faʻatonu ai. E talia le asiasiga a le isi vaega (BV, SGS, ma isi)
O se aofaʻi lava o mea le atoatoa o le fogāʻeleʻele vaaia e
e manaʻomia le tuʻuina atu o se faʻamautinoaga faʻavaitaimi.
E tatau ona aveese pe tipi ese le mea sese i totonu o le
tapula'a o mana'oga i le umi. O le paipa ua mae'a
e tatau ona sa'o lelei.
