Stainless hlau yeeb nkab fittings tuaj yeem raug cais raws li lawv qhov muaj pes tsawg leeg, cov khoom siv, kev siv, thiab kev sib txuas.
Raws li kev sib xyaw ua ke, lawv tuaj yeem muab faib ua Cr-raws li (400 series), Cr-Ni-raws li (300 series), Cr-Mn-Ni (200 series), thiab nag lossis daus- hardening series (600 series). Cr-raws li stainless hlau yog nyob rau hauv ferritic thiab martensitic stainless hlau tsev neeg, muaj siab hardness thiab lub zog, tab sis kuj tsis muaj zog corrosion kuj. Cov qib ib txwm muaj xws li 409, 410, thiab 430. Cr-Ni-raws li stainless hlau yog paub rau lawv zoo heev corrosion kuj thiab machinability, thiab yog cov feem ntau siv stainless hlau series. Cov qib hom muaj xws li 304, 316, 321, thiab 347. Cov Cr-Mn-Ni series muaj cov machinability zoo thiab corrosion kuj, tab sis nws corrosion kuj yog me ntsis qis dua 300 series. Los nag- hardening stainless steels txhim kho lub zog thiab hardness los ntawm precipitated theem, ua rau lawv haum rau daim ntaub ntawv uas yuav tsum tau muaj zog thiab siab corrosion kuj.
Stainless hlau yog cais los ntawm qib kev ua tau zoo, feem ntau raws li nws cov khoom siv xws li tensile lub zog, tawm lub zog, thiab elongation. Cov qib kev ua tau zoo hauv kev lag luam suav nrog 45, 50, 60, 70, thiab 80, nrog cov lej siab dua feem ntau qhia tias muaj zog dua.
Los ntawm daim ntawv thov, stainless hlau yeeb nkab fittings yuav categorized rau hauv lub luj tshib, tees, crosses, reducers, thiab kaus mom. Lub luj tshib yog siv qhov twg cov kav dej khoov, feem ntau suav nrog 45-degree thiab 90-degree luj tshib. Tees yog siv qhov twg peb cov kav dej sib txuas. Reducers yog siv los txuas ob lub kav dej sib txawv.
Los ntawm txoj kev sib txuas, stainless hlau yeeb nkab fittings tuaj yeem muab faib ua plaub hom: lub qhov (socket joint), threaded joint, flanged joint, thiab welded joint. Lub qhov (socket) txuas txuas los ntawm kev ntxig cov yeeb nkab steel hlau mus rau hauv lub qhov (socket) ntawm qhov haum thiab vuam raws ntug. Threaded pob qij txha txuas los ntawm nruj haum ntawm cov xov sab hauv thiab sab nraud. Flanged pob qij txha txuas siv flanges thiab bolts, haum rau daim ntaub ntawv uas yuav tsum tau nquag disassembly. Welded pob qij txha txuas ncaj qha los ntawm vuam, muab kev sib txuas zoo thiab kev sib khi zoo.
