Arung arai nnan ni hta, dai arung arai ni gaw 85% daram rai nga ai. Butt-}elbows ni hpe lang ai shaloi, shanhte hpe ayan san seng hkra tawn da nna, transmission thread ni gaw aten kadun laman hta sau bang ra ai. Fault langai hpe mu ngut ai hpang, dai jak hpe kalang ta jahkring kau ra ai majaw, mara a majaw byin ai hpe chye lu na re. Pressing hte welding elbows ni hpe pipe lahkawng hpe nominal diameter langai sha hte matut nna, pipe ni hpe℃90 hte shinggrup na matu lang ai.
Arung arai ni ra ai lam ni
Arung arai laika (MTC) hpe jaw ra ai, dai hta, tsi mawan ni a nsam, jak rung atsam (tensile n-gun, hkai lu hkai sha ai n-gun) ni lawm ai.
