Characteristics and Application of Low Temperature Seamless Steel Pipe
Main grades or steel grades of low temperature steel pipes:
ASTM A333-Grade1, Grade4, Grade6, Grade7, Grade9, Grade10
ASTM A334-Grade1, Grade6, Grade7, Grade9
API 5CT: N80, L80-1, L803Cr, P110
Implementation standards for low temperature steel pipes:
ASTM A333, ASTM A334, API SPEC 5CT
Features of low temperature steel pipes:
Low temperature steel pipe is a kind of steel with special properties. It is developed on the basis of carbon structural steel. Due to its unique corrosion resistance and good mechanical properties, it is mainly used for petroleum, chemical and other equipment pipelines and Accessories. The low-temperature steel pipe is a medium-carbon structural steel. It can be used in both cold and hot temperatures and low-temperature steel pipes. It has good mechanical properties, low prices, and wide sources, so it is widely used. Its biggest weakness is low hardenability, and it is not suitable for workpieces with large cross-sectional dimensions and relatively high requirements.
PMC low temperature resistant seamless pipe, using low-sulfur, low-phosphorus, high-purity steel and calcification treatment, can effectively reduce the low-temperature brittleness of the steel and improve the impact toughness of the product. The company has a 0~-100°C cooling tank, which can conduct low-temperature impact tests in batches to ensure the quality stability of the manufactured products.
The use environment of low temperature steel pipe:
A333 and A334 low-temperature resistant pipes are mainly used for -45℃～-195℃ low-temperature pressure vessel pipes and low-temperature heat exchanger pipes, and can also be used for fluid transportation pipes in low-temperature environments. The API 5CT low temperature resistant oil casing is mainly used for oil well production in extremely cold regions.
Production process:
Cold drawn and hot rolled
The scope of application of low temperature steel pipe:
Widely used in pipelines for transporting oil and natural gas in liquid transportation projects; superheated steam traps for feed water heaters, condensers and pulverized coal boiler feed water preheaters in urban water supply and heating pipe network systems; petrochemical industry for oil refining Reactors, reboilers, etc. in catalytic cracking units in factories; machinery industry is used to make various molds, and automobile industry is used to make dies and wire drawing dies for cold stamping; connecting pipelines and valves of distillation equipment heat exchangers in petroleum refineries ; Equipment and components of food and drinking water treatment systems and pipelines in agricultural irrigation and drainage systems; connecting pipes for air supply and return air devices in mine sand wells; corrosion-resistant pipes in seawater utilization devices; various refrigerators and freezers Inlet air pipe of machine; thermal insulation of digester and condensing pipe of papermaking machinery; oil field injection well water wall heating and pressure reducer; thermal power plant steam-water separation reheater; natural gas trunk line transportation soft cable; submarine optical cable protective cover; outdoor heat Cooling and heating pipelines; longitudinal shock isolation and noise reduction pillars of expressways; urban street lamp poles.

Seamless Pipes for Energy Equipment
Seamless pipes play an extremely important role in energy equipment, especially in systems that need to withstand harsh working conditions such as high temperature, high pressure, and corrosion. Since there are no welded seams in its manufacturing process, seamless steel pipe has higher structural integrity, uniform mechanical properties and excellent pressure bearing capacity, making it the preferred piping material in the energy sector. Permanent Steel Manufacturing Co., Ltd. has carefully…
Can Galvanized Steel Pipes be Painted?
Galvanized steel pipe is a common metal pipe, which is widely used in construction, water supply, HVAC and other fields due to its excellent anti-corrosion performance. However, with the diversification of usage scenarios, many people have begun to consider painting galvanized steel pipes to improve their aesthetics or further enhance their protective effect.
