Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q4: What makes stainless steel stainless?

A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q5: Can stainless steel rust?

A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q6: What is the difference between galvanized steel and galvalume steel?

A6: Galvanized steel is metallic coated with Zinc in various coating weights. Minimum recommended for painted metal roofs is G90. Galvalume is a zinc and aluminum coated steel that becomes an alloy and is recommended in either painted or bare applications with a minimum coating weight of AZ50. Galvalume has an excellent performance life in bare exposures. Hence if you are using a bare panel use galvalume and if painted use either.

Q7: Is there a difference in thermal conductivity between stainless steel and steel?

A6: Yes. Stainless Steel has a lower thermal conductivity rate than steel; approximately 1/3 to 1/5th depending on the material.

Q8: Is there a difference in electrical conductivity between stainless steel and steel?

A8: Yes. Steel is generally more conductive than stainless steel. Steel has resistivity in the range of 10~20Ωm, while stainless has a resistivity of approximately 60~72Ωm.

Q:How are steel pipes used in the construction of biomass power plants?: Steel pipes are used in the construction of biomass power plants for various purposes, including transporting and distributing steam, water, and other fluids throughout the facility. They are also used for the construction of boiler systems, as well as for conveying fuel and exhaust gases. In addition, steel pipes are essential for the structural integrity of the plant, providing support and durability in various applications.

Q:Why seamless steel pipe called seamless steel pipe?: Seamless is relative to welded steel pipe, because welded steel pipe is welded with steel strip, seamless steel pipe is made of whole round steel empty, no welding seam.

Q:What is the maximum temperature that steel pipes can withstand?: The maximum temperature that steel pipes can withstand depends on the grade and type of steel used. Generally, carbon steel pipes can withstand temperatures up to 1000°C (1832°F), while stainless steel pipes can handle temperatures up to 1200°C (2192°F). However, it is essential to consult the specific specifications and guidelines provided by the manufacturer for accurate temperature limits.

Q:What are the different end finishes for steel pipes?: There are several different end finishes for steel pipes, depending on their intended use and the specific requirements of the application. Some of the most common end finishes for steel pipes include: 1. Plain End: This is the simplest and most common type of end finish, where the pipe is cut square at both ends without any additional treatment or threading. Plain end pipes are typically used for low-pressure applications or when the pipe will be connected using welding methods. 2. Beveled End: A beveled end finish involves cutting the pipe at an angle, usually 30 or 37.5 degrees, to facilitate easier welding and create a stronger joint. Beveled end pipes are commonly used for butt-welding applications, where two pipes are joined together by aligning the beveled ends and welding them. 3. Threaded End: In this end finish, the pipe is threaded at both ends to allow for easy connection with threaded fittings or couplings. Threaded end pipes are commonly used in plumbing and gas distribution systems, as well as for applications that require frequent disassembly and reassembly. 4. Coupled End: Coupled end finishes involve the installation of couplings or connectors at each end of the pipe. This allows for quick and easy connection of pipes without the need for additional threading or welding. Coupled end pipes are often used in oil and gas pipelines or in applications where rapid installation is required. 5. Grooved End: A grooved end finish involves cutting grooves into the pipe's ends and using mechanical couplings or fittings to join the pipes together. This type of end finish is commonly used in fire protection systems, as well as for large-diameter pipes that require quick and efficient assembly. 6. Flanged End: Flanged end finishes involve attaching flanges to the pipe ends, which can be bolted together to create a secure and leak-proof connection. Flanged end pipes are commonly used in applications that require easy disassembly and reassembly, such as in chemical plants or refineries. It is important to note that the choice of end finish for a steel pipe depends on factors such as the application, the required joint strength, the type of connection method, and the compatibility with other system components. Consulting with a professional or referring to industry standards is recommended to ensure the correct end finish is selected for a specific application.

Q:What are the different types of steel pipe elbows?: There are several different types of steel pipe elbows, including 45-degree elbows, 90-degree elbows, and 180-degree elbows. These elbows are used to change the direction of the flow in a piping system and are available in various sizes and materials to suit different applications and requirements.

Q:How are steel pipes coated to prevent corrosion?: Steel pipes are coated to prevent corrosion through a process called galvanization, where a layer of zinc is applied to the surface of the pipes. This zinc coating acts as a protective barrier, preventing the steel from coming into direct contact with moisture and other corrosive elements in the environment.

Q:Can steel pipes be used for underground chemical pipelines?: Indeed, underground chemical pipelines can utilize steel pipes. The chemical industry, among other industries, extensively employs steel pipes owing to their robustness, potency, and resistance to corrosion. To ensure suitability for underground chemical pipelines, it is crucial to select an appropriate steel grade that can withstand corrosion from the specific chemicals being transported. Furthermore, the resistance of steel pipes to chemical corrosion can be further augmented through the implementation of suitable coating and lining techniques. Regular inspection and maintenance are imperative to guarantee the integrity and safety of the underground chemical pipeline system.

Q:What are the different methods of pipe repair for steel pipes?: There are several methods for repairing steel pipes, including spot repair, slip lining, pipe bursting, and pipe relining. Spot repair involves cutting out and replacing a small section of the damaged pipe. Slip lining involves inserting a smaller diameter pipe into the existing pipe to reinforce it. Pipe bursting involves breaking the old pipe while simultaneously installing a new one. Pipe relining involves inserting a liner into the damaged pipe and then curing it in place to create a new, seamless pipe within the existing one. The choice of method depends on the extent and location of the damage, as well as budget and time constraints.

Q:Can steel pipes be used for sewer systems?: Yes, steel pipes can be used for sewer systems. However, they are less commonly used compared to other materials such as PVC or concrete pipes. Steel pipes are generally used for larger diameter sewer lines or in specific situations where they are preferred due to their strength and durability.

Q:How are steel pipes used in the transportation industry?: Steel pipes are used in the transportation industry for various purposes, including the construction of pipelines for transporting oil, gas, and other fluids. They are also used in the manufacturing of vehicles, such as cars, trucks, and trains, where they are commonly used for exhaust systems and structural components. Additionally, steel pipes are utilized in the construction of bridges, tunnels, and other infrastructure projects that support transportation networks.
