Description
Technical field
The present invention relates to tubular object extruding production technical field, and in particular to a kind of coating on metal connecting tube and its
Preparation method.
Background technology
Welded still pipe is also referred to as welded tube, be with steel plate or strip welded after cans made of steel pipe, general scale 6
Rice.Welded still pipe simple production process, production efficiency is high, and description is more, and equipment investment is few, but common intensity is less than seamless steel
Pipe.
Since the 1930s, with quality strip steel rolling production develop rapidly and weld and inspection technology enters
Step, weldquality are constantly lifted, and the description of welded still pipe is increasing, and instead of seamless steel in increasing field
Pipe.Welded still pipe is divided into ERW and spiral welded pipe by the form of weld seam.Classify by production method：Technique classification-arc welding
Pipe, resistance weld pipe, (high frequency, low frequency) gas welded pipe, the continuous furnace welding of tube.
More small-bore welded tube uses straight weld, and heavy caliber welded tube then more uses spiral welding；It is divided into by steel tube end part shape
Circular welded tube and special-shaped (side, square type etc.) welded tube；It is divided into mining fluid conveying welded still pipe, lowpressure stream by material and purposes difference
Body conveying galvanized welded pipe, carrier roller of belt conveyer electric welded steel pipe etc..According to the gauge table in existing national standard, by outer
The ascending sequence of footpath * wall thickness.
Product standard：
Welded tube common material is：Q235A, Q235C
Q235B、16Mn、20#、Q345、L245、L290、X42、X46、X60、X80、0Cr13、1Cr17、00Cr19Ni11、
1Cr18Ni9,0Cr18Ni11Nb etc..
The blank that welded still pipe uses is steel plate or strip, is divided into the continuous furnace welding of tube, electric welding (resistance because its welding procedure is different
Weldering) manage and automatic arc welding pipe.Because the difference of its Type of Welding is divided into two kinds of ERW and spiral welded pipe.Because of its end shape
It is divided into circular welded tube and special-shaped (square, flat etc.) welded tube again.Welded tube is divided into following some kinds because its material is different with purposes：
GB/T3091-2008 (low-pressure fluid conveying welded still pipe).Mainly for delivery of water, coal gas, air, oil and take
The general lower pressure fluid such as warm heat water or steam and other purposes pipes.Its represent material as：Q235A level steel.
GB/T14291-2006 (mining fluid conveying welded still pipe).It is mainly used in mine pressure wind, draining, axle methane use
Straight seam welded steel pipe.It represents material Q235A, level-B steel.
GB/T12770-2002 (the stainless steel welded steel pipe of mechanical structure).It is mainly used in machinery, automobile, bicycle, family
Tool, hotel and restaurant decoration and other mechanical parts and structural member.Its represent material 0Cr13,1Cr17,00Cr19Ni11,
1Cr18Ni9,0Cr18Ni11Nb etc..
GB/T12771-1991 (the stainless steel welded steel pipe of fluid conveying).Mainly for delivery of low pressure Korrosionsmedium.
Material is represented as 0Cr13,0Cr19Ni9,00Cr19Ni11,00Cr17,0Cr18Ni11Nb, 0017Cr17Ni14Mo2 etc..
Separately have, decoration uses welded stainless steel pipe (GB/T 18705-2002), the stainless steel welded tubing (JG/ of architectural decoration
T 3030-1995), and heat exchanger is with welded still pipe (YB4103-2000).
And welded tube is also to be used as connection, although the technique of production is very simple, due to material
And the problem of the reason for external environment condition tends to cracking, fracture, paint layer from surface comes off, thus easily cause
Damage, reduces service life, brings the loss of many.
