Description

ASTM A572 Grade 50 Round Seamless Carbon Steel Pipe High Strength Low Alloy (HSLA) Pipe

ASTM A572 Grade 50 High Strength Low Alloy Pipe

ASTM A572 Grade 50 Carbon Steel Seamless Pipe Supplier Overview

The ASTM A572 standard refers to high-strength low alloy steel pipes (HSLA Pipes) that comply with the American standard ASTM A572. The ASTM A572 standard includes multiple HSLA grades, such as grade 42, grade 50, grade 55, grade 60, and grade 65. The grades in ASTM A572 standard are related to the strength of the steel. For example, the strength of ASTM A572 grade 50 HSLA pipes is approximately 380 Mpa.The strength of grades 42, 55, 60 & 65 in MPa is as follows: 290, 380, 415, and 450.

Manufacturing Process

The production process of ASTM A572 seamless alloy steel pipes is divided into the following steps:

Round bar → Heating → Piercing → Three roll oblique rolling, continuous rolling or extrusion → Tube detachment → Sizing (or reducing) → Cooling → Straightening → Hydrostatic testing (or flaw detection) → Marking → Warehousing.

Seamless steel pipes are made from steel ingots or solid billets that are perforated into tubes, and then hot-rolled, cold-rolled, or cold-drawn.

Seamless steel pipes are mainly divided into hot rolled seamless steel pipes, cold drawn seamless steel pipes, and cold rolled seamless steel pipes. This article mainly provides a detailed explanation of these three production processes.

Strict Product Inspection

1.Chemical Component Analysis

2.Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation)

3.Technical Properties (Flattening Test, Flaring Test, Bending Test, Hardness Test, Blow Test, Impact Test etc)

4.Exterior Size Inspection

5.Nondestructive Test (Ultrasonic flaw detector, Eddy current flaw detector),

6.Hydrostatic Test

Each ASTM A572 Grage 50 steel pipe must pass the inspection layer by layer. Only the products that pass the inspection can leave the factory. Never let an unqualified product flow into the market.In addition to conventional water pressure testing and X-ray weld inspection experiments, we also conducted metallographic experiments, chemical composition testing, yield strength testing, tensile strength testing, impact testing, and other steel pipe inspection experiments, and recorded them.

Maintenance And Care | Tips For Extending The Lifespan Of ASTM A572 Grade 50 Carbon Steel Seamless Pipes

1. Store in a clean and unobstructed area away from factories and mines that produce harmful gases or dust

2. On the site, weeds and all debris should be removed, and thick walled steel pipes should be kept clean.

3. In the warehouse, materials that are corrosive to thick walled steel pipes such as acid, alkali, salt, cement, etc. should not be stacked together to prevent confusion and mutual corrosion.
