1. What should I pay attention to when storing seamless carbon steel pipes?
When storing seamless carbon steel pipes, the following points should be noted to prevent damage and rust: 1. Store in a dry, ventilated, rainproof and moisture-proof warehouse to avoid direct contact with rainwater and groundwater; 2. The pipes should be placed on a wooden bracket or steel frame, away from the ground (at least 10cm), to prevent moisture and corrosion; 3. Different materials, specifications and surface treatments of pipes should be stored separately to avoid confusion and collision; 4. For pipes with anti-rust treatment, avoid scratching the surface anti-rust layer; 5. Regularly check the pipes, and timely clean the rust if found, and re-coat anti-rust oil.
2. Can seamless carbon steel pipes be bent or cut?
Yes, seamless carbon steel pipes can be bent or cut according to the actual installation needs. For bending: low carbon steel seamless pipes have good plasticity and can be bent by cold bending or hot bending; medium and high carbon steel seamless pipes have poor plasticity, and need to be preheated before bending to avoid cracking. For cutting: common cutting methods include sawing, cutting, plasma cutting, etc. Sawing is suitable for small-diameter pipes, cutting is suitable for medium and large-diameter pipes, and plasma cutting is suitable for thick-walled pipes. We can provide bending and cutting processing services according to the customer's requirements before delivery.
3. What is the difference between API 5L Gr.B and ASTM A106 Gr.B seamless carbon steel pipes?
API 5L Gr.B and ASTM A106 Gr.B are two common grades of seamless carbon steel pipes, and their main differences are as follows: 1. Application field: API 5L Gr.B is mainly used for oil and gas transportation pipelines (including onshore and offshore), while ASTM A106 Gr.B is mainly used for high-temperature and high-pressure fluid transportation (such as steam, water, oil) in industrial and power fields; 2. Mechanical performance: the tensile strength of API 5L Gr.B is 415-550MPa, and the yield strength is ≥240MPa; the tensile strength of ASTM A106 Gr.B is 415-590MPa, and the yield strength is ≥240MPa, the latter has slightly higher tensile strength; 3. Standard requirements: API 5L pays more attention to the toughness and pressure-bearing capacity of the pipe, while ASTM A106 pays more attention to the high-temperature performance of the pipe.
4. Do you accept OEM or ODM orders for seamless carbon steel pipes?
Yes, we accept both OEM and ODM orders for seamless carbon steel pipes. For OEM orders: we can produce pipes according to the customer's brand, logo, packaging and specifications, and the products will be sold under the customer's brand. For ODM orders: we can provide professional R&D and design services according to the customer's specific needs (such as special working environment, performance requirements), develop new specifications or new types of seamless carbon steel pipes, and provide exclusive solutions for customers. We will strictly protect the customer's brand and technical information to ensure the uniqueness of the products.
5. What is the after-sales service for seamless carbon steel pipes?
We provide comprehensive after-sales service to solve the customer's worries. The after-sales service includes: 1. Quality guarantee: if the pipe has quality problems (such as material unqualified, dimensional deviation, defects) within the quality guarantee period (usually 1 year), we will provide free replacement or refund; 2. Technical guidance: provide professional technical guidance on the installation, use and maintenance of the pipe; 3. Complaint handling: respond to the customer's complaints within 24 hours, and send professional personnel to solve the problem within 7 working days; 4. Follow-up service: regularly follow up the use of the pipe by customers, and provide maintenance suggestions and technical support.
