Ubhetyebhetyeumbhobho wentsimbiisakhiwo sinesakhiwo esine-four sombhobho wensimbi oguquguqukayo, i-internalmost layer is extruded thermoplastic tube, i-transmission fluid evela kwitywina;phakathi kweengqimba ezimbini ze-lining ye-carbon-ezaliswe ityhubhu ye-polyethylene, enokumelana nemitha ye-ultraviolet yesakhono sexeshana, kunye nokulawula i-static yangaphandle.Umaleko ongaphandle ukhutshelwe ikhaka elishinyeneyo langaphandle, ukugcina umzantsi wombhobho kwiimpembelelo zangaphandle.

Ukucaciswa kwexabiso loxinzelelo lombhobho wensimbi eguquguqukayo lisebenza ngokuhambelana nokuhlelwa kwe-ANSI, njengebakala le-300 elilingana ne-5.15MPa;ibakala 400 elilingana .89MPa;I-10.3MPa i-flexible steel grade 600 isiseko esilinganayo soyilo yi-API17J17K kunye ne-RP17B yomhlaba Inkcazo yoyilo lombhobho oguquguqukayo kancinane ngaphakathi kokutenxa kwiinkcukacha ze-API, sebenzisa iindlela zokuhlela ze-API17J kunye nezixhobo, uxinzelelo, ukuxinwa kunye nemida yomonakalo imiselwe uluhlu.

Uvavanyo luyilwe ngokuhambelana ne-APIRP17B i-terminal fitting ukuhlangabezana neemfuno zokugcina ingqibelelo yesakhiwo, ukuqinisekisa ukuba iimfuno zokutywinwa kwangaphakathi kunye nezangaphandle ze-extruded layer, kwaye zingaqinisekisa ukuba umthwalo we-tensile kunye noxinzelelo uthunyelwa kwisakhiwo sombhobho.Emva kokuqhushumba kwesampulu yofakelo lwetheminali kunye novavanyo lwe-axial tensile.
