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 -
What are the performance characteristics and applications of high-quality seamless stainless steel pipes for fluid transmission
First, what are the performance characteristics of seamless stainless steel pipes? 1. Corrosion resistance: Stainless steel has strong corrosion resistance, resisting the erosion of various media such as acids, alkalis, and salts. It can be used for a long time in harsh working environments, main...Read more -
How to Properly Store Straight Seam Steel Pipes
During the manufacturing process of straight seam steel pipes, manufacturers need to have excellent control over the extrusion pressure. This is because during welding, when the temperature of the two pipe blank edges reaches the welding temperature, pressure is applied to them. This pressure all...Read more -
