Pipe Knowledge

ASTM A335 pipe, also known as Chrome-Moly Alloy Pipe, is widely used in various industries for high temperature and high pressure services. It is available in different grades such as P5, P9, P11, P22, and P91. Market data shows that it is one of the most commonly used alloy pipes in industries such as boiler […]

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 […]

People are often confused when it comes to accurately describing the dimensions or sizes of steel pipes, as well as effectively communicating their desired size to the seller. Any misunderstandings or the purchase of an incorrect size could lead to significant trouble. So, what are the right ways to express the dimensions of a steel […]

Sour services steel pipe is applied for pipelines in the corrosive environment. As we know, line pipe corrosion is an important factor affecting its safety service and service life. It will cause the leakage of oil and gas pipeline, some cases even explosion. Pipe corrosion has a big threaten to personal safety and environment pollution, […]

What is LSAW pipe means LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold […]

As we know steel pipe and steel plate mechanical performances depends on two aspects: One is the heat treatment type; Another one also the most important factor is the chemical elements effect to these steel material. Common chemical elements in steel pipes and steel plates Common chemical elements in steel is C, Mn, S, P, […]

People always confused about when to use description of steel pipe, when to use steel tube. Moreover, you must met the situation that from different country different area, some call it pipe where some other call tube, actually for the same thing. And since they are looks like the same products, round shape, hollow in […]

Steel pipe unit weight (kg/m or lb/ft) is an important description that should 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 find out this […]

API 5L pipes are carbon steel pipes used for oil and gas transmissions. They include pipes manufactured in seamless and welded (ERW, SAW). The grades include 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 […]
