What are the quenching technologies for straight seam welded pipes
03-05
Surface quenching and tempering heat treatment for straight seam welded pipes is typically performed using induction heating or flame heating. The main technical parameters are surface hardness, localized hardness, and effective hardened layer depth. Hardness testing can be done using a Vickers hard
Is broaching suitable for the appropriate precision requirements of seamless steel pipes
03-04
In the high-precision machining of seamless steel pipes, broaching is a highly efficient and precise processing method. It's like using a "custom mold" to "shape and polish" the steel pipe, achieving good surface quality and dimensional accuracy in a single process. However, many people are unclear
What are the changes in anti-corrosion methods and common defects of plastic-coated steel pipes
03-03
First, what are the changes in anti-corrosion methods for plastic-coated steel pipes?The earliest anti-corrosion method for plastic-coated steel pipes was inner and outer polyethylene. Due to adhesion problems, it evolved to inner and outer epoxy. However, the outer epoxy layer was not resistant to
What are the common processing problems and quality inspection methods for plastic-coated steel pipes
03-02
First, common problems in the production and processing of plastic-coated steel pipes:1. Weld defects: Severe weld defects are often remedied by manual mechanical grinding, resulting in uneven surfaces and affecting aesthetics. Pickling and passivation only on the weld also leads to uneven surfaces.
What are the technological challenges and breakthroughs in processing small-diameter seamless steel pipe fittings
02-28
First, Analysis of the Core Processing Challenges in Machining Small-Diameter Seamless Steel Pipe Fittings(I) Processing Bottlenecks Caused by Material Characteristics of Small-Diameter Seamless Steel Pipe FittingsNo. 45 steel is a medium-carbon structural steel with a carbon content of 0.42%-0.50%.
What are the common welding methods and precautions for stainless steel pipes
02-27
First, what are the welding methods for stainless steel pipes?(1) Argon Arc Welding: Stainless steel pipes require deep penetration, no oxide inclusions, and a minimal heat-affected zone. Tungsten inert gas (TIG) shielding provides good adaptability, high welding quality, and good penetration perfor
