I. Identification and Information Carrying (Core "ID Card")This is the most basic and direct function of marking. It assigns unique identification information to each steel pipe or batch, typically including:Basic Parameters: Steel grade/material, specifications (outer diameter, wall thickness), len

Stainless steel's dominant position in the food industry stems from its series of irreplaceable superior properties:Excellent Corrosion Resistance: Food environments are complex, often involving corrosive media such as water, acids (such as glycolic acid and acetic acid), alkalis, and salts. Chromiu

The core function of oil casing and tubing is to construct a stable wellbore structure, ensure safe operation, and achieve efficient oil and gas resource extraction.I. Core Application Scenarios: Constructing Wellbore Structures to Cope with Complex Subsurface EnvironmentsThis is the most basic and

I. Pipes for Hull StructureThese steel pipes are mainly used for hull support and frame construction, requiring extremely high strength, toughness, and corrosion resistance.Rib and Frame Pipes: In modern ships, especially yachts, small cargo ships, and superstructures, round or rectangular steel pip

I. Main Types and StandardsShipbuilding steel pipes are mainly divided into two categories:Structural steel pipes: Used to bear the main loads of the hull, they must meet the specifications of classification societies (such as CCS, DNV, ABS, LR, etc.), and are usually made of carbon manganese steel.
