API 5L pipe is a carbon steel pipe used for oil and gas transmissions, it includes pipes manufactured in seamless and welded (ERW, SAW). Materials covers API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore and sour services. API 5L is the implementation standard of steel pipe […]

People always confused about how to describe steel pipe dimensions (sizes) in correct ways, or how to clarify to seller what exactly pipe size we are going to purchase. In case any misunderstandings or a different size we purchased, that will be a big trouble. So, what are the exactly right ways to express the […]

Steel pipe unit weight (kg/m or lb/ft) is an important description that shall be specified in the purchase order. Then how to calculate the steel pipe weight per foot or per meter? Through pipe weight and total quantity meters we will get the whole weight for the pipe request. Another way to get is to […]

Always in pipeline systems we met the material with NACE MR0175/ISO 15156 pipe or fittings, so do you really know what is the major differences between NACE carbon pipe and normal carbon steel pipe? And how is the cost for nace material? So today we are going to introduce NACE MR0172 / ISO 15156 from […]

OCTG is the abbreviation of Oil Country Tubular Goods, it mainly refers to the piping products that are applied in oil and gas production (drilling activities). OCTG pipe normally is manufactured based on API or related standard specifications. It also could be taken as a collective name for Drill pipe, Steel Casing Pipe and Tubing […]

API 5CT is standard technical specifications for steel casing and tubing pipes used for oil wells in petroleum and natural gas industries. Besides casing and tubing, it also includes pup joints, coupling stock, coupling material, and accessory materials, and establishes requirements for three product specification levels (PSL-1, PSL-2, and PSL-3). The requirements for PSL-1 are […]

Concrete coated pipe also called concrete weight coating pipe (CWC pipe), is the steel pipe external with concrete weight coating (Mixed with cement, aggregates, reinforced steel mesh, and water), to provide strong downward force protection or a negative buoyancy for the pipelines. This pipe is commonly used in sub-sea (submarine) pipelines, with adding the proper […]

Solid CRA lined pipes or CRA clad (cladding) pipes are known as bimetal pipe consists an inner alloy pipe for corrosion-resistant and an outer carbon steel pipe which can withstand external and internal pressure. Normally mother pipe in carbon steel of API 5L B to X70, ASTM A53B, or A106B. Clad or lined with alloy […]

Steel pipe pile is a type of steel piling material. It is usually referred to the carbon steel pipe manufactured in seamless or welded (SSAW or LSAW), used for supporting and stabilizing the foundation of a building. So a pipe pile is a structural construction material. Pipe pile applications Steel pipe pile is a most […]

API Coupling refers to the steel couplings that used in connecting casing pipe and tubing. Also known by OCTG coupling, it is usually manufactured in seamless type, material grade same with the pipe body (API 5CT K55/J55, N80, L80, P110 etc), same PSL or providing higher grades than requested. Same heat treatment also applicable, except […]

Butt weld fittings is one of the most popular connection type in pipeline systems. It always been required in large quantities in different industries, and especially for the large diameter pipelines. What is Butt Weld Fittings Butt weld is to connect pipes or fittings ends by welding. It’s a weldable steel pipe fitting that would […]

As we know there are four connecting types for the pipe fittings: Socket weld, butt weld, threaded, and flanged. In terms of steel pipe fittings that you would be able to use for your pipeline projects, you will find two of them to be quite popular: Socket weld fittings and butt weld fittings. However, since […]
