JIS G3429 STH12 STH22 34Crmo4 paipa uamea mo CNG Sili
Fa'amatalaga o oloa
O le maualuga o le mamafa o le gas cylinder tube o se ituaiga o paipa uʻamea e leai se mea, e masani ona taʻua o seamless tube uʻamea mo pusa kasa, faʻaaogaina lautele i ituaiga uma o tane maualuga maualuga, faʻapea foʻi ma pusa kasa fale gaosimea, afi afi, taavale CNG cylinders, taavale c.
O le mea autu o le kasa cylinder tube o: 38Mn6, 30CrMo4, Vaega, 4130X, Vasega C, Vasega E, STH11, STH12, STH21, STH22.
O le tulaga masani o le JIS G3429 ua fa'amaonia ai paipa u'amea e leai ni mea e fa'aaogaina mo le gaosiga o pusa kasa e leai ni mea.JIS 3429 tubes e tatau ona faavasegaina i 5 grades, Vasega STH22 tubing o se medium ma maualalo carbon chromium-molybdenum ituaiga faʻaaogaina mo vaʻa mamafa e faia e seamless auala gaosiga.O le siosiomaga o le auʻaunaga o pusa kasa maualuga o loʻo tuʻuina atu i luma manaʻoga maualuga atu mo le faʻatinoina o le faʻalava uamea,
mea STH22 e sili atu ona faʻaaogaina e avea o se mea faʻagogo i le siosiomaga galue maualuga ona o lona malosi maualuga i le maualuga o le vevela ma le malosi tele o le fetolofi.
34CrMo4 o se uʻamea faʻapipiʻi uʻamea ma le maualuga o le tumau ma le malosi fetolofi i le maualuga o le vevela, e tutusa ma le STH22 vasega uamea.E masani ona faʻaaogaina mo le gaosiga o le paʻu poʻo vaega faʻavae o loʻo galue i lalo o uta maualuga e pei o le felauaiga o vaega o taavale ma afi;turbine-generator rotor, spindle, mamafa avega ave taavale, vaega tele vaega, locomotive traction gear, supercharger transmission gear, tuala tua, tootoo fesootai ma le tautotogo pipii ma le uta tele, e mafai foi ona faaaoga mo le suauu vili paipa sooga ma meafaigaluega fagota i lalo. 2000m.

O Tatou Fa'amanuiaga
1.HengYang poʻo le TPCO maualuga faʻapitoa faʻapitoa ma lona mama maualuga o le sila.
2. o lona mafiafia puipui tutusa ma maualuga saʻo, lelei le malamalama, gaosiga ma fua e fai si maualuga, faafaigofieina foʻi faufau faumea convergent,
3.E mafai ona tatou gaosia le lautele paipa ogalaau e mafai ona faia i le 40 ~ 944.4mm, le mafiafia aupito maualalo puipui o 3.5 mm,
4.A o se faʻamatalaga masani o kesi kesi, o le taimi tuʻuina atu e vave.
