The mechanical properties analysis of galvanized pipes requires a comprehensive evaluation based on material properties, galvanizing process and application scenarios. The following is a detailed analysis based on the latest industry standards and research data: I. Basic materials of galvanized pipes 1. Substrate type 1. Carbon steel: commonly used Q195, Q215, Q235 (corresponding to American […]
Galvanized seamless pipes are seamless steel pipes processed by hot-dip galvanizing or electro-galvanizing processes. They combine the high strength of seamless pipes with the corrosion resistance of the galvanized layer and are widely used in scenarios with high requirements for corrosion resistance and pressure resistance. The following is an analysis from two aspects: core characteristics […]
There are mainly the following cutting methods for anti-corrosion steel pipes: Mechanical cutting External installation cutting: Using the principle similar to that of a lathe, the cutting equipment is installed on the outside of the steel pipe, and the pipe mouth is cut and beveled by a turning tool. This method has a large span […]
Galvanized steel pipes used for domestic water supply are all connected by threads, also known as threaded connections. Generally, water supply pipes with a nominal diameter not exceeding 100 mm and a nominal pressure not exceeding 1 MPa can be connected by threads. The threads of the connecting pipes are also divided into two types, […]
Galvanized steel pipes rely on their own high toughness, good bending and welding properties, but are mainly made of important parts that require extremely high wear resistance and crack resistance. The thickness of the wear-resistant layer of wear-resistant alloy pipes varies, generally controlled between 3-120mm, so their hardness grades are also different. Compared with ordinary […]
Hot-dip pure zinc products, code is GI. The characteristics of hot-dip pure zinc products are beautiful surface, good corrosion resistance and good processability. It is divided into two types, one is normal zinc spangles, and the other is zinc-free spangles. In the past, hot-dip galvanized products always had some zinc spangles on the surface because […]
The function of the pipeline is mainly to transport liquids or other solids. It can be said to be the most commonly used equipment in our lives. 3 treatment methods for pipeline anti-corrosion. 1. What are the treatment methods for pipeline anti-corrosion? 1. Pipeline external anti-corrosion design Petroleum asphalt is the oldest pipeline anti-corrosion layer, […]
Before hot-dip galvanized steel pipe welding, the hot-dip galvanized steel pipe is mainly heated, and welding begins after temperature control for 30 minutes. The heating, solid layer temperature and heat treatment process of welding are automatically controlled by the temperature control cabinet of the heat treatment process. The far-infrared crawler heat treatment furnace is used […]
The buried pipeline uses plastic-coated steel pipe for the transmission line tower, which is composed of towers connected by tower pole devices. The pole tower is made of steel. The surface of the tower pole steel and the inner and outer surfaces of the tower pole are hot-dipped with a modified polyethylene plastic layer. The […]
1. Galvanized pipes and fixtures should be cleaned of foreign objects such as oil, residual salt, paint, etc. before heat treatment; 2. The fixtures used in the vacuum furnace for the first time should be degassed and purified in advance at a vacuum degree not lower than the required degree of the workpiece; 3. Workpieces […]
