First, how is polishing stainless steel pipe fittings performed?Brightly polished stainless steel pipe fittings have a clean, shiny appearance, are easy to clean, and have an invisible protective film that prevents corrosion and scale buildup, resulting in a longer lifespan. Matte-finish brushed sta

Austenitic stainless steel is softened through solution treatment. Generally, the seamless stainless steel pipe is heated to approximately 950–1150℃ and held at that temperature for a period of time. This allows carbides and various alloying elements to fully and uniformly dissolve in the austenite.

First, the welding details for galvanized steel pipes include:1. Galvanized steel pipes with a diameter greater than 100mm should be connected using flanges or compression fittings.2. To ensure welding quality, the weld joint should be treated with galvanizing. The galvanized layer should be cleaned

Accurately measuring the length of spiral steel pipes is crucial for manufacturers. Based on years of production experience, four methods for length measurement have been summarized:1. Improved Encoder Length Measurement: This is an indirect measurement method. The length of the spiral steel pipe is

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

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

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

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.
