Specification for Characteristic Testing of Precision Seamless Tubes
Precision seamless pipes are pided into two types, hot-rolled seamless steel pipes and cold-rolled seamless steel pipes due to their different production processes. Cold-drawn (cold-rolled) tubes are ...
Defects that May Occur in the Production of Hot-rolled Seamless Steel Pipes
Hot-rolled seamless steel pipe is a kind of round, square and rectangular steel with a hollow section and no joints on the periphery. When the bending and torsion strength is the same, the weight is l...
Defect Analysis of High-precision Cold-rolled Seamless Steel Pipe
Analysis of quality defects on the inner and outer surface of high-precision cold-rolled(cold drawn) seamless steel pipe:
Cold rolled seamless steel pipes have the characteristics of no oxide layer on...
The Influence of Inclusions on the Fatigue Strength of Seamless Steel Pipe Materials
Factors affecting the fatigue strength of seamless steel pipe materials: inclusions.
The inclusion itself or the hole created by it is equivalent to a tiny gap, which will produce stress concentrat...
Acceptance Standard of ERW, LSAW Straight Seam Steel Pipe
Acceptance of ERW,LSAW straight seam steel pipe:
1 The quality inspection and acceptance of straight seam steel pipes shall be carried out by the technical quality supervision department of the suppli...
What Will Happen to Seamless Steel Pipes in Low Temperature Environments?
1. Low temperature embrittlement of seamless steel pipes ------ In low temperature environment, deformation energy is small. In a low temperature environment, the phenomenon that the elongation and s...
Causes of Cracking of Thick-walled Seamless Steel Pipes and Countermeasures
There are many reasons for the longitudinal cracking of thick-walled seamless steel pipes, including material reasons and process reasons. Taking thick-walled seamless steel pipe as an example, if the...
What Corrosion Phenomena Will Occur in Thick-walled Steel Pipes in the Construction Industry?
Metals can react with oxygen in the atmosphere to form an oxide film on the surface. The iron oxide formed on ordinary carbon steel will continue to oxidize, causing the rust to continue to expand and...
How to Improve the Collapse Resistance of Oil Casing Pipe?
In fact, oil casing collapse is a common form of damage to oil casing, but although it is common, how can oil casing pipe damage be prevented? The anti-collapse performance of oil casing has always be...
How to Clean the Oil Casing Bare Pipe?
About the cleaning of oil casing bare pipe:
The bare oil casing pipes are cleaned and arrive at the processing plant. Before the formal processing, the oil stain, lime soil, oxide scale rust and old c...
