Speciality and Advantages
Our company has been dedicated to producing stainless steel seamless pipe since 2003, owning complete producing technology and abundant managing experience.
The raw material such as mother tube, round bar we use is from Chinese biggest and well-known steel mill: Walsin Steel and Yongxing Steel.
We have advanced NDT equipments for the tests such as Eddy Current test, Ultrasonic test, Hydraulic test and so on.
We have ISO 9001 and PED certificate, and the Third Party Inspection Certificates such as TUV, BV, Lloyd’s, SGS, etc, also can be provided according to customers’ requirements,
Wooden case package which is strong and suitable for sea transportation is our main method to pack the pipes. And the economical packing method such as packed in bundles is also welcomed by some customers.
The tolerance control we use is D4/T4 (+/-0.1mm) on both inside and outside Diameter and Wall Thickness, which is much higher than international standard ASTM, DIN.
The surface condition is one of our main advantages: in order to meet different requirements for surface condition, we have annealing and pickling surface, bright annealing surface, OD polished surface, OD & ID polished surface etc.
In order to keep the inside surface of pipe clean and make it free from deburring, our company develops the unique and special technology --- Sponge Washing with high pressure.
We have complete after-sale service to deal with the problems in time.
- Q:How do you calculate the pipe volume for a specific application?
- To calculate the pipe volume for a specific application, you need to multiply the cross-sectional area of the pipe by its length. The cross-sectional area can be determined by using the formula for the area of a circle (πr^2), where r is the radius of the pipe. Once you have the cross-sectional area, multiply it by the length of the pipe, and you will have the volume.
- Q:Can stainless steel pipes be coated?
- Stainless steel pipes have the capability to undergo coating procedures. Coating these pipes serves multiple purposes, such as bolstering their durability, preventing corrosion, providing insulation, and enhancing their aesthetics. There exist diverse options for coating stainless steel pipes, including epoxy coatings, polyurethane coatings, and fusion-bonded epoxy coatings. These coatings are applied to the surface of the stainless steel pipes using various techniques, such as spraying, dipping, or electrophoretic deposition. The selection of the appropriate coating relies on the specific requirements of the application and the environment in which the pipes will be utilized. By coating stainless steel pipes, their lifespan can be significantly extended and their performance can be improved, making them suitable for a wide range of industries including oil and gas, chemical, water treatment, and construction.
- Q:What is the weight of a stainless steel pipe?
- The weight of a stainless steel pipe can vary depending on its dimensions and thickness. Generally, it is determined by calculating the volume of the pipe and multiplying it by the density of stainless steel.
- Q:How do you prevent galling in stainless steel pipes?
- One way to prevent galling in stainless steel pipes is by applying an anti-seize compound or lubricant to the threaded connections. This helps to reduce friction and prevents the surfaces from seizing together. Additionally, ensuring proper thread engagement and avoiding excessive tightening can also help prevent galling.
- Q:What is the standard size range for stainless steel pipes?
- The standard size range for stainless steel pipes varies depending on the industry and application. However, in general, stainless steel pipes are available in a wide range of sizes, starting from small diameters of around 0.5 inches (12.7 mm) to large diameters of up to 48 inches (1219 mm) or even larger in some cases. The wall thickness of stainless steel pipes can also vary, ranging from thin-walled pipes with a thickness of a few millimeters to heavy-walled pipes with thicknesses exceeding an inch. The specific size range for stainless steel pipes may be determined by factors such as the intended use, pressure requirements, and industry standards. It is important to consult relevant specifications and standards to determine the appropriate size range for a specific application.
- Q:Can stainless steel pipes be welded?
- Indeed, it is possible to weld stainless steel pipes. Due to its remarkable resistance to corrosion and strength, stainless steel is widely favored in various industries. Among the numerous techniques employed to connect stainless steel pipes, welding is a prevalent approach. Nonetheless, it is crucial to employ suitable welding techniques and equipment to guarantee a successful weld. Each grade of stainless steel has distinct welding prerequisites, necessitating the use of a filler material that corresponds to the specific grade being welded. Furthermore, it is imperative to adequately clean and prepare the surfaces that are to be welded to ensure a robust and long-lasting joint.
- Q:How do you calculate the bending radius of stainless steel pipes?
- To calculate the bending radius of stainless steel pipes, you need to consider several factors. The bending radius is determined by the diameter of the pipe, the wall thickness, and the type of stainless steel being used. First, you need to determine the outside diameter (OD) of the pipe. This can be measured directly or obtained from the pipe specifications. Next, you should identify the wall thickness of the pipe. This information is available in the pipe specifications or can be measured using a caliper. Once you have the OD and wall thickness, you can calculate the inside diameter (ID) of the pipe by subtracting twice the wall thickness from the OD. This is because the wall thickness is evenly distributed on both sides of the pipe. Now that you have the ID, you can calculate the bending radius. The bending radius is typically expressed as a multiple of the pipe's OD. The general rule is that the bending radius should be at least three times the OD for stainless steel pipes. However, this value may vary depending on the specific application and the type of stainless steel being used. It is important to note that bending stainless steel pipes beyond their recommended bending radius can lead to deformation, cracking, or failure. Therefore, it is crucial to follow the manufacturer's guidelines and consult with an engineer or a professional experienced in working with stainless steel pipes for accurate calculations.
- Q:What is the lifespan of stainless steel pipes?
- The lifespan of stainless steel pipes can vary depending on various factors such as the grade of stainless steel used, the environment in which they are installed, and the maintenance practices followed. However, in general, stainless steel pipes have a long lifespan and can last for several decades or even longer with proper care and maintenance.
- Q:Can stainless steel pipes be used for solar power plants?
- Yes, stainless steel pipes can be used for solar power plants. Stainless steel is highly resistant to corrosion and can withstand the harsh environmental conditions typically found in solar power plants. It offers excellent durability and longevity, making it a suitable choice for transporting various fluids and gases in the solar power plant infrastructure.
- Q:Are stainless steel pipes suitable for underground heating systems?
- Yes, stainless steel pipes are suitable for underground heating systems. Stainless steel is highly resistant to corrosion and can withstand the harsh conditions of being buried underground. It is durable, long-lasting, and can handle high temperatures and pressures, making it an ideal choice for heating systems. Additionally, stainless steel pipes are easy to install and maintain, providing a reliable and efficient solution for underground heating systems.
