What are the problems and solutions for uneven anti-corrosion coating thickness on spiral welded steel pipes
Spiral welded steel pipes are mainly used as fluid pipes and piling pipes. After the pipes are manufactured, if they are used for water transport, anti-corrosion treatment is usually applied to the inner or outer surface of the spiral welded steel pipe. Common anti-corrosion treatments include 3P...Read more -

How to Correctly Select and Use the 15CrMoG Boiler Steel Pipes
1. Selection Stage of 15CrMoG Boiler Steel Pipes Based on operating parameters: Accurately consider parameters such as boiler operating temperature, pressure, and medium composition. If the operating temperature is consistently between 500-550℃, the pressure is in the medium-high pressure range, ...Read more -
What are the characteristics of steel pipe welding technology
The weld seam is the weakest and most critical link in welded steel pipes. In high-pressure, corrosive, or high-purity fluid transportation scenarios, an improperly treated weld seam is a potential leak point and source of failure. How can you determine if the weld seam of the industrial welded s...Read more -
What are the selection recommendations for cold-drawn steel pipes used in mechanical structures
Cold-drawn steel pipes are widely used in mechanical structures due to their high dimensional accuracy, low surface roughness, and excellent mechanical properties, such as drive shafts, support columns, hydraulic system pipelines, and machine tool components. In the design and processing of mecha...Read more -
Chip Control and Process Adjustment in the Machining of High-Toughness Seamless Steel Pipes Fittings
First, what are the core characteristics of chip formation in high-toughness seamless steel pipes fittings? High-toughness seamless steel pipes, due to their alloying elements such as chromium, nickel, and molybdenum, possess high tensile strength (≥600MPa), elongation after fracture ≥20%, and im...Read more -
Do you know the suitable temperature for welding straight seam steel pipes
Welding, also known as fusion welding, is a manufacturing process and technique that joins metals or other thermoplastic composite materials (such as plastics) by heating, applying high temperature, or high pressure. There are three welding methods: 1. Fusion welding: The workpiece is heated to f...Read more -
What are the heating requirements for spiral welded steel pipes
Heating spiral welded steel pipes before hot rolling not only improves the metal’s plasticity and reduces deformation force, but also facilitates rolling. Furthermore, during the heating process, certain structural defects and stresses introduced by the ingot can be eliminated. Spiral welde...Read more -
