About Cold Drawn Seamless Welded Pipes

Cold drawn welded pipe is made of seamless hot-rolled steel pipe and straight-slot welded pipe as a blank. Cold drawing refers to the method of applying a pulling force on one end of the material to pull the material through a mold hole. Welded pipe is made by forming flat products (strip, sheet or plate) into the desired shape, in this case, normally round. Welded pipes can be produced in large sizes without any size restriction. The pipe has high strength. The cold drawn welded pipe is made for commercial uses. A cold drawn welded (CDW) pipe is a kind of steel pipe that is fabricated utilizing the cold drawing process followed by welding. This interaction includes pulling a strong steel bar or billet through a pass on to shape it into a cylinder, and afterward welding the edges together to make a persistent length of line. Cold drawn welded pipes offer benefits like exact aspects, smooth surface completion, and worked on mechanical properties.

Outstanding Strength & Precision

Thanks to the cold drawing technique and meticulous heat treatment processes, these seamless welded pipes achieve a hardness range of HRC 10-40 and tight tolerance of 0.5%. The result is superior mechanical strength and dimensional accuracy, ideal for demanding structural or pressure applications.

Customizable & Quality Assured

With customizable sizes, surface treatments such as pickling and galvanizing, and a selection of packagings including bundled and wooden boxes, these pipes are tailored to diverse project requirements. Rigorous inspectionincluding third party acceptanceand clear marking ensure traceability and confidence in quality.

Versatile Industrial Applications

These pipes serve a variety of sectorsfrom supporting structures in automobiles to conveying fluids in oil and gas or chemicals. Their seamless construction, corrosion resistance, and adaptability to both welded and seamless connections make them a reliable choice for industry professionals.

FAQs of Cold Drawn Seamless Welded Pipes:

Q: How are Cold Drawn Seamless Welded Pipes manufactured and what techniques are used?

A: These pipes are produced using cold drawing, which involves pulling the pipe through dies to achieve precise dimensions and a smooth surface. Depending on the grade, advanced heat treatments such as annealing and stress relieving are applied to optimize hardness and structural integrity.

Q: What testing processes ensure the quality and reliability of these pipes?

A: Each pipe undergoes stringent testing, including eddy current, ultrasonic, and hydraulic tests. These non-destructive methods are crucial for identifying any discontinuities or weaknesses, ensuring the pipes meet high industry standards for performance and safety.

Q: Where can these pipes be used and what are their main benefits for different industries?

A: These pipes are particularly suited for oil and gas, chemical, mechanical, automobile, and structural applications. Their high strength, corrosion resistance, and seamless or welded options make them ideal for conveying fluids under pressure and supporting heavy loads.

Q: What packaging and delivery options are available for these pipes?

A: To protect the pipes during transit, several packaging methods are offered, including bundling, plastic wrapping, and sturdy wooden boxes. Pipes are fitted with plastic end caps for additional safety and shipped in an annealed, normalized, or as-welded condition according to customer preference.

Q: What is the minimum order quantity and can third-party inspection be arranged?

A: The minimum order quantity for these pipes is 1 ton, making them accessible for both small and large-scale projects. Third-party inspection is accepted to assure buyers of the products compliance with required standards and specifications.

Q: How are the pipes marked for identification, and what information is included?

A: Each pipe is marked with crucial information such as size, grade, and heat number, ensuring complete traceability and compliance with industry standards as required.
