Nggulung selang kanthi longgar penting banget kanggo nyegah kinks utawa bend, amarga tikungan sing cetha bisa nyuda selang lan nyuda umure. Nalika nyimpen selang welding, priksa manawa digantung utawa dilebokake kanthi rata tinimbang digulung kanthi kenceng.

Kajaba iku, selang welding kudu katahan bebas saka rereged, utamané lenga, grease, utawa zat liyane sing bisa nanggepi gas sing ditransfer, utamané ing selang oksigen, ngendi malah jumlah cilik saka kontaminasi bisa nggawe kahanan mbebayani. Yen selang welding kapapar nggunakake tugas abot utawa lingkungan atos, reresik biasa lan pangopènan kudu dileksanakake kanggo mbusak sembarang buildup saka rereged.

Sadurunge saben nggunakake, iku penting kanggo mriksa kabeh fittings lan sambungan saka selang welding kanggo mesthekake lagi aman ditempelake lan ora bocor. Nggunakake gulungan selang utawa pancing panyimpenan uga bisa mbantu ngatur selang lan nyegah karusakan saka tangling utawa abrasion. Kanthi ngetutake praktik pangopènan lan panyimpenan kasebut, selang las bakal njaga safety, linuwih, lan kinerja, njamin lingkungan kerja sing aman kanggo operator.

Twin-line Structure and Safety Design Principles: Welding Hoses
