LSAW (Longitudinal Submerged Arc Welded) steel pipes are widely used in various industries for transportation of fluids or as structural support. To ensure the quality and safety of these pipes, various standards are developed by international and national organizations. Here are some of the most common standards used for LSAW steel pipes:
API (American Petroleum Institute) 5L: This standard specifies the requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. The standard covers LSAW pipes with a diameter range from 16 inches to 60 inches.
ASTM (American Society for Testing and Materials) A252: This standard covers the manufacture of welded and seamless steel pipes with a nominal wall thickness of 0.375 inches or less, primarily used for piling purposes. The standard covers LSAW pipes with a diameter range from 16 inches to 100 inches.
EN (European Norm) 10219: This standard specifies the technical delivery conditions for cold-formed welded structural hollow sections of circular, square, or rectangular shape. The standard covers LSAW pipes with a diameter range from 406 mm to 1626 mm.
GB/T (Chinese National Standard) 9711: This standard specifies the requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. The standard covers LSAW pipes with a diameter range from 219 mm to 3048 mm.
ISO (International Organization for Standardization) 3183: This standard specifies the requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. The standard covers LSAW pipes with a diameter range from 219 mm to 1820 mm.
In summary, there are several standards available for LSAW steel pipes, each with its own specific requirements and specifications. The appropriate standard should be selected based on the specific requirements of the project and the application in which the pipes will be used. Compliance with these standards ensures the quality and safety of the pipes and helps to avoid potential issues during their use.
LSAW (Longitudinal Submerged Arc Welded) steel pipes are used in a variety of applications such as oil and gas transportation, water transmission, and structural support. To protect these pipes from corrosion and ensure their longevity, various types of coatings are used.
Here are some of the most common coatings used on LSAW steel pipes:
Fusion-bonded epoxy (FBE) coating: FBE is a thermosetting polymer coating that is applied to the surface of the steel pipe using electrostatic spray deposition. This coating is known for its excellent adhesion, chemical resistance, and durability. It is commonly used in oil and gas pipelines, water pipelines, and other corrosive environments.
Three-layer polyethylene (3LPE) coating: This coating system consists of a fusion-bonded epoxy primer, a copolymer adhesive, and a polyethylene outer layer. It provides excellent resistance to mechanical damage, chemical attack, and weathering. It is commonly used in offshore pipelines, water pipelines, and other harsh environments.
Three-layer polypropylene (3LPP) coating: This coating system is similar to 3LPE, but the outer layer is made of polypropylene instead of polyethylene. Polypropylene is more resistant to high temperatures and UV radiation than polyethylene. It is commonly used in high-temperature pipelines and other environments where UV radiation is a concern.
Coal tar enamel (CTE) coating: CTE is a traditional coating that has been used for many years. It is made from coal tar and is applied to the surface of the steel pipe using a hot-applied method. It provides excellent resistance to water, soil, and chemicals. It is commonly used in water pipelines and other underground applications.
Concrete weight coating (CWC): CWC is a special type of coating that is used to add weight to the pipe and improve its stability in underwater environments. It consists of a layer of concrete that is applied to the surface of the steel pipe using a centrifugal process.
In summary, there are several types of coatings available for LSAW steel pipes, each with its own unique properties and applications. The selection of the appropriate coating depends on the specific application and the environment in which the pipe will be used.
LSAW (Longitudinal Submerged Arc Welded) steel pipes are commonly used in various industries for transportation of fluids or as structural support. Proper packing of these pipes is crucial for their safe transportation and storage. Here are some of the most common packing methods used for LSAW steel pipes:
Bare pipe: This packing method is used when the pipes are transported short distances or stored in a covered area. The pipes are bundled together and secured with steel straps or wire ropes. This method is not suitable for long-distance transportation or storage in harsh outdoor environments.
Plastic caps and steel bands: This method involves capping both ends of the pipes with plastic caps and securing them with steel bands. This packing method provides some protection against dust and moisture but is not suitable for long-distance transportation or storage in harsh outdoor environments.
Woven bags and steel bands: This method involves wrapping the pipes in woven bags and securing them with steel bands. This packing method provides better protection against dust and moisture and is suitable for short to medium-distance transportation and storage in covered areas.
VCI (volatile corrosion inhibitor) paper and steel bands: This method involves wrapping the pipes in VCI paper, which releases a corrosion inhibitor that protects the pipe from corrosion during transportation and storage. The pipes are then secured with steel bands. This packing method is suitable for long-distance transportation and storage in harsh outdoor environments.
Wooden crates: This method involves placing the pipes in wooden crates and securing them with steel bands. This packing method provides the highest level of protection against dust, moisture, and mechanical damage. It is suitable for long-distance transportation and storage in harsh outdoor environments.
In summary, there are several packing methods available for LSAW steel pipes, each with its own level of protection and suitability for different transportation and storage conditions. The appropriate packing method should be selected based on the specific requirements of the project and the conditions in which the pipes will be transported and stored.
