Steel pipe hi a siamna, machinery siamna leh engineering field-a hman tlanglawn ber pakhat a ni. Mahse, basic steel pipe chi hrang hrang a awm a, chu chu material, production process, performance, leh application-ah te danglamna nasa tak a awm a ni. Heng danglamnate hriatthiamna hian i hmanna tur steel pipe chi khat tling ber i thlan theih nan a pui ang che.
I. Material classification hmanga danglamna .
1. Carbon steel pipe .
Carbon steel pipe hi basic steel pipe chi hrang hrang zingah a tam ber a ni. A bul berah chuan iron leh carbon atanga siam a ni a, carbon content hi a tlangpuiin 0.02% atanga 2.11% inkar a ni. Carbon awm zat a zirin low-carbon steel, medium-carbon steel, leh high{6}}Carbon steel pipe-ah te then theih a ni.
Low-Carbon steel pipe (Q235 ang chi): chakna tlemte, toughness tha tak, leh welding awlsam tak a pe. Building structure, piping system leh hmanna dang dangah pawh hman a ni nasa hle.
Medium-high carbon steel pipe: chakna sang zawk nei mahse toughness tihtlem. Hardness sang zawk mamawh application atan a tha a, chu chu mechanical parts leh springs te a ni.
2. Alloy steel pipe .
Alloy steel pipe te hi carbon steel atanga siam niin, metallic element dang, chromium, nickel, leh molybdenum te dah tel a ni a, chu chuan corrosion resistance, strength, emaw high-temperature performance a tichak a ni.
Stainless steel pipe (304 leh 316 ang chi): Chromium leh nickel a awm a, corrosion resistance tha tak a pe bawk. Chemical, food processing, leh medical equipment industry-ah te hman an ni tlangpui.
Low-Alloy High-Sterength steel pipe (Q345 ang chi): manganese leh silicon ang chi element a awm a, chu chuan carbon steel pangngai aiin chakna a sang zawk. Bridge leh high-pressure vessels ang chi structure atan an tha hle.
3. Seamless leh welded steel pipe .
Seamless steel pipe: Perforation emaw extrusion process hmanga siam a nih avangin weld seam an nei lo a, pressure resistance nasa zawk an pe bawk. High-pressure, high{2}}temperature environment, boiler leh oil pipeline te tan an tha hle.
Welded steel pipe (ERW leh LSAW ang chi): Coiling leh welding steel plate hmanga siam a nih avangin a man a tlawm zawk-a tha zawk a, low-pressure fluid transportation, tui leh gas system ang chi te pawh a tha zawk.
II a ni. Thil siam chhuah dan hrang hrang hmanga danglamna .
1. Hot-Rolled steel pipe .
Hot-rolled steel pipe chu temperature sang takah an roll a. A chhung lam structure inang tlang tak a nei a, mahse a chung lam chu a hrual thei bawk. Structural parts leh machining atan an hmang tlangpui.
2. Khaw lum-Rolled/cold-Drawn steel pipe .
Cold-rolled or cold-Drawn steel pipe chuan low-temperature processing a tawk a, chu chuan dimensional accuracy sang tak leh surface smooth tak a siam a ni. Dimensional requirement khauh tak nei, precision machinery leh automotive parts te tan pawh a tha hle.
iii a ni. Dilna hmanga danglamna .
1. Structural steel pipe .
Construction, bridge, leh mechanical support-a hman ber, Q235B steel pipe ang chi, chakna leh weldability ngaih pawimawh.
2. Fluid hmanga phurh chhuah steel pipe .
Tui, oil leh gas, welded steel pipe (API 5L) phurh nan hman a ni a, a chhung lam bang mawi tak leh corrosion resistance a ngai a ni.
3. High-Pressure/high-Thawhlang steel pipe te chu a awm thei ang.
Boiler pipe leh oil casing ang chi hmanna atan chuan seamless alloy steel pipe hi a tlangpuiin pressure leh temperature nasa tak tuar thei turin an hmang thin.
iv. Engtin nge basic steel pipe dik tak kan thlan ang? Building structures: Carbon structural steel (Q235 ang chi) hi a tha zawk.
Chemical/Food Industries: Stainless steel pipe (304, 316 ang chi) hi a tha zawk.
High-Pressure Fluid phurh chhuahna: Seamless emaw alloy steel pipe hman a ni.
Precision Machinery: Cold-Drawn emaw Cold-Rolled steel pipe chu dimensional accuracy a awm theih nan thlan a ni.
Basic steel pipe inthlauhna hi material leh craftsmanship-ah chauh a lang lo va, an application scenario-ah pawh direct-in a nghawng a ni. Steel pipe chi dik thlan hian project himna a tichangtlung mai bakah sum senso a ti tlem a, service life pawh a ti rei bawk.
