I-Poipe Spools

I-dibane idalwe ngokwenza i-fact ezimbini kwelinye enye kwaye ibatywine ngokusebenzisa iirhasi ezahlukeneyo. Iiflethi zihlala zenziwa nge-aluminium, i-bronze, brass okanye i-carbon sensi. Ezona zinto zikhethwayo kwizicelo zeflethi jikelele yintsimbi yekharbon yekharbon. Ngapha koko, iiflevu zinokungeniswa ngaphakathi neentlobo ezahlukeneyo zelines. Ngokwesiqhelo, izixhobo zeflethi zikhethwe njengezixhobo ezifanayo kunye nezinto zombhobho. Olu khetho lwezixhobo luqhutywa ukwenzela ukuthintela ingozi ye-gavanic. Ukhetho olufanelekileyo lwezinto ezibonakalayo zigqitywe ngokwe-ASTM A-182.

I-tees ye-weltiked ye-weldied yenziwa ngenxa ye-ASTM Asme B16.11 imigangatho. Le migangatho ingenisa kwaye ithathe isigqibo soxinzelelo olufanelekileyo kunye namanqanaba amaqondo obushushu, i-radises kunye nempahla efunekayo yokuveliswa kweenkomo. Ngaphaya koko, iMigangatho ye-B16.11 ivunyelwe kuphela kwikharbon kunye ne-alloy steels. I-tees ye-weltiked ye-welding inokuveliswa ibe ziindidi ezintathu zoxinzelelo. Iklasi yama-3000, iklasi 6000 kunye neklasi ye-9000.

I-tees ye-bott ye-bott inokugcina ukuhamba ngokuthe ngqo okanye ukunciphisa ukuhamba okuthe tyaba kuxhomekeka kwinkqubo yepayina. Amasebe okunciphisa (ukunciphisa i-tees) yenza uqhagamshelo olukhoyo kunye nombala ophambili. I-radius ye-tees ihlala incinci kunomgca ophambili wokuhamba. I-radius ye-tees ethe tye iveliswa ngendlela enee-radias ezifanayo nomgca ophambili wokuhamba.

Iiflethi zezinto ezisebenza njengesinxibelelanisi phakathi kwemibhobho ephambili, i-valves okanye iimpompo. Elona phelelo libalaseleyo lokusetyenziswa kweflethi ngokulula ngokulula ukucoca kunye nokuhlolwa kwendawo enxulumene neflethi. Iiflethi zihlala ziveliswa ngokusebenzisa iindlela zedysing okanye ezikrolayo. Iinkqubo zeFlanji zenza ihlazo phakathi kwezinto ezahlukeneyo.

I-teeked ye-weldake ye-weldied nayo yenza i-angle ye-perperm phakathi kwemigca exhunyiweyo. Basebenzise izicelo zoxinzelelo oluphezulu. Ngokuchasene ne-tees ye-lelt ye-weldad, i-teeked ye-Weldid isetyenziswa kwizicelo apho i-radius yombhobho ngokubanzi incinci. I-teecked ye-welded ye-welding ayifuni inkqubo yokuthambisa ngaphambi kokuba i-welding. Ke ngoko, ezi ntlobo ze-tees zilungile kwezinye iinkqubo apho isebe liphela kufuneka ligcinwe ngendlela efanayo ngaphambi nasemva kwe-welding.

Ukucaciswa kweentlobo zefleki zenziwa ngemigangatho ye-AST16.5. Njalo ke ukuhlelwa njenge; Intamo ye-Wold, i-Slip-kwi-sheeke ye-shed, i-geneg-genent, i-theine eyimfama. Iiflethi ze-WOld zilula kufuneka ziqonde. I-cylindrical bulge kunye ne-radius yanda ngokuthe ngcembe iqhagamshelwe kwilungu eliphambili.
