What is AISI steel?

what-is-aisi-steel

SAE International, as a standards organization, maintains several alloy numbering systems, one of which, for steel grades, is the SAE steel grades system. In the 1930s and 1940s the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.


Use of Ceramic-Lined Steel Composite Pipeceramic-used

The liquid pipe transport has been widely used in the industries of electric power, metallurgy, coal, petroleum, chemical engineering, building materials, mechanism and so on.


How better packaging the abrasion resistant pipe

What is the meaning of ASTM standard?

astmlogoa

ASTM International, known until 2001 as the American Society for Testing and Materials (ASTM), is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.


Welded Pipe vs. Seamless Pipe

12cr2mo

Welded vs. seamless. It’s a debate that’s been around for a long time, and it’s still going strong today.

Round tubes

banner_dom-tubing

Round tubes are round, cylindrical shapes that are hollow. Round tubes have a wide variety of structural and architectural applications. Unlike pipes, tubes are measured by their outside diameter and their wall thickness.

ASTM A333 pipesdually from ASTM and other qualified standards providers.

A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders, masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.


  DOM Tubing

banner_tubing

DOM Tubing (Drawn over Mandrel) is a cold drawn 1020 / 1026 electric resistance welded tube with all the flash removed prior to cold drawing. In comparison to other tubing, DOM tubing is produced to more exact OD and ID tolerances, and has the highest weld strength possible.

How to calculate a steel pipe theoretic weight

bg_steelpipeThe weight of a pipe depends on the weight density of the material that composes the pipe as well as the physical volume of the pipe.

EN 10204 3.1 Certification Vs EN 10204 3.2 Certification

banner_astm-a213-alloytube

EN10204 is a Euronorm (issued by the European Community) specification that describes different types of material test reports and certifications.


What is the Difference Between A53 Pipe vs A106 Pipe

banner_astm-a53

Because they have different scope and specify different type of pipe, then the manufacturing process and required quality control test and inspection will be different to each other.


Welded Steel Pipe VS Seamless Steel Pipe

banner_weld-steel-pipes

Pipes and tubings are vital elements in upstream oil and gas. From control lines to electrical lines, tubings can be used in diverse applications. In deepwater environments, coiled tubings could run up more than 70,000 feet to produce hydrocarbon.


What is DOM tubing used for

banner_dom-tubing

DOM Steel Tube is produced using uniformly high quality C1020 steel strip and is formed and electric resistance welded into its basic shape.


Wear-resistant ceramic-lined composite pipe performance which?

shs-self-propagating-process

Wear-resistant ceramic lining composite pipe using the main technology is the centrifugal casting composite ceramic technology.


Heavy Wall Seamless Carbon Pipe
