ASTM A106/ASME SA106 is the standard specification for seamless carbon steel pipe used for high-temperature services. It includes three grades: A, B, and C, with Grade B being commonly used. This type of pipe finds applications in various industries, including pipeline systems for oil and gas, water, and mineral slurry transmission. It is also used […]

What weld overlay means Weld overlay is a metal overlay route where overlay welding deposits a functional alloy layer on a base metal surface so the wetted surface meets corrosion or wear requirements. In project documents, weld overlay cladding, cladding welding, clad welding, and welding overlay cladding are often used as near-synonyms; in supplier narratives, […]

Steel tee is a T-shaped pipe fittings that has three branches, normally has two forms with Equal Tee and Reducing Tee (Tee reducer), both are used to divide (combine) the pipelines to adjust the flow rate and change the direction. Steel pipe tee has been be widely used in different industries, according to material types […]

Steel pipe elbows are critical fittings in piping systems, designed to change the direction of fluid flow while maintaining pressure integrity and system efficiency. As one of the most commonly used pipe fittings, elbows are available in a wide range of materials, dimensions, and connection types to meet the diverse needs of industrial and commercial […]

Weathering steel, is atmospheric corrosion resistance steel, also known by corten steel. It is the material that between normal carbon steel and stainless steel and with low alloy content. So corten steel is the carbon steel that added with copper (low Cu), Chrome (low Cr) elements, these elements exist to bring anti-corrosion performances. Besides, it […]

Fire sprinkler pipes and fittings are specialized piping components designed to transport water or fire suppression liquids throughout a building’s fire protection system. Commonly manufactured from carbon steel or ductile iron, these pipes serve as the primary medium to connect sprinklers, hydrants, valves, and other firefighting equipment. Within industry terminology, they are also referred to […]

Thermal expansion pipe is also called seamless pipe or hot expanding seamless pipe. As it’s name, the pipe is made from hot expanding processes, mainly there are two types: 1. Original seamless steel pipe and 2. hot expanded seamless pipe (Based on original seamless pipe hot expanding). So when we say thermal expansion pipe usually […]

Plasma cutting technology used a lot in steel and metal cutting processes, especially when integrated with CNC plasma arc cutting. So how much do you know about this cutting technology? And how is the differences between other metal cutting methods. Below articles we will tell you all the tips and guide if you need this […]

Waterjet cutting is to use high pressure water to cut or profiling steels and especially for highly brittle materials. It delivers smooth and precise cuts through the mechanical sawing action. This is a versatile process in that it cuts through almost every material. Octal provides customize waterjet cutting services according client requirements. Things you should […]

Large diameter steel pipe normally refers to the pipe diameter above 16 inch and up to 100 inch, it plays an important role in oil and gas transmissions. For long distance pipeline projects large diameter pipe could carry more liquid and with big flow rate. Especially for recent years, the use of large diameter steel […]

Flame cutting (also known as oxy fuel cutting), it is to use the heat burned from oxy fuel gas, to cut steel materials or the hard metals to the panels or profiles required. It can cut steel thickness from 1 mm to 1200 mm. And in most cases it used to cut steel plate thickness […]

Laser cut metal is a processed metal by laser cutting technology. Metal materials mainly types in sheet metal (steel plate) and fabricated in carbon, alloy or stainless steel. About laser cutting Laser cutting is to cut different materials especially steel metals with the help of laser beam. It is majorly used for industrial manufacturing applications, […]
