Ip magniy anodi sof magniy yoki MG-Mn qotishma sovuq haddelenmiş qilingan. Ochiq tutashuv potentsiali (Cu/CuSO4) -1,7V, uzunlik birligi uchun massasi esa 0,37kg/m. Qarshiligi 100Ω·m dan katta yoki unga teng bo'lgan muhitda foydalanish uchun javob beradi. Magniy bandining chiqish oqimi 50Ō·m qarshilik bilan tuproqda 10mA/m va chuchuk suvda 3mA/m 150Ō·m dir. Xuddi shu massadagi lentali magniy anodining sirt maydoni ingot magniy anodiga qaraganda ancha katta. Misol uchun, 11 kg magniy ingotining sirt maydoni 0,27 m2, 11 kg magniy lentasi uzunligi 30 m, 1,9 m2 sirt maydoni esa avvalgisidan 7 baravar ko'p. Anodning chiqish oqimi sirt maydoniga proportsional va qarshilikka teskari proportsionaldir. Anod sifati anodning ishlash muddatini belgilaydi. LOYIHALASHTIRISHDA MAHALLIY TUVROQGA QARShILISHNI E'tiborga olish kerak va magniy lentasini kesishish yoki korpus trubkasiga o'rash quvurning ishlash muddati bilan taqqoslanadigan xizmat muddatiga ega deb hisoblanishi kerak. Agar dizayn muddati 20 yil bo'lsa va mahalliy tuproq qarshiligi past bo'lsa, magniy tasmasini ishlatish maqsadga muvofiq emas, balki shpindel magnezium anot.
The conventional design of the cross section or casing pipe is usually installed with magnesium tape winding method. The sectional size of the banded magnesium anode used in the Shaoxing natural gas utilization project is (19±0.5)mm×(9.5±0.5)mm. Each steel pipe is wound with two banded magnesium anodes, which are symmetrically distributed on both sides of the pipeline. A binding belt is set every 1-2m, and the material is nylon belt. The cable and magnesium anode are welded by filling tin. The insulation layer adopts composite insulation structure, which is composed of epoxy resin, electrical adhesive tape, plastic adhesive tape, heat shrinkable sleeve and anti-corrosion adhesive tape from inside to outside. Each layer of adhesive tape is overlapped when winding. The cable and the pipe are connected by double-point thermite welding. The cable runs smoothly and has a surplus. The distance between the two solder joints is >10 sm, qoplamaning sinishi o'lchami 3 sm × 3 sm, ta'mirlash hajmi esa 5 sm × 5 sm dan katta. Biroq, haqiqiy qurilishda magniy kamarini o'rnatishning ushbu usulini ishlatish qiyin, ayniqsa kesishgan qismdagi quvur liniyasi orqaga tortilganda, jarohatlangan magniy kamari qarshilik qarshiligini oshiradi va magniy kamarining tushishi oson. o'chiring va buzing. Shuning uchun, kesishgan qismdagi quvur liniyasi uchun magniy kamarini ishlatmaslik tavsiya etiladi, lekin chiqish va kirish joylarida ingot magniy anodlarini qo'shish va anod iste'molini muntazam ravishda aniqlash uchun sinov qoziqlarini o'rnatish tavsiya etiladi. Qopqoqdagi quvurlar uchun magniyli lentani o'rash o'rniga magniy lentasi miqdorini kamaytirmasdan quvurga parallel ravishda o'rnatish tavsiya etiladi, bu esa trubaning magniy lentasiga zarar bermasdan, korpusga kirishini osonlashtiradi.
