9. FAQ: Composite Pipe Technology & Installation
Q1. What is a composite pipe? How does it differ from conventional steel pipes?
A: A composite pipe is a pipeline composed of multiple bonded or clad layers (e.g. steel + polymer + alloy), engineered for superior anti-corrosion, abrasion, and chemical resistance. Unlike mono-material steel pipes, composite pipes can synergistically blend the strengths of metal and non-metal materials, reducing weight and increasing design life.
Q2. Which standards certify composite pipe manufacturers?
A: Major standards include ISO 9001 (quality management), API 5L/5LD (oil & gas pipes), DNV.GL (offshore compliance), and ISO 14692 (GRP/GRE pipe for petroleum).
Q3. What are typical materials and clad alloys used in Laser Clad Pipe?
A: The base is usually carbon steel, stainless steel, or duplex; the cladding is supplied by nickel-based alloys like Inconel 625, Incoloy 825, or cobalt-based alloys, chosen for precise corrosion/erosion protection.
Q4. What is the maximum working temperature and pressure for Laser Clad Pipe?
A: Laser Clad Pipe can sustain up to 150°C and 15 MPa continuous operation, per qualification tests aligned to DNV.GL and API 5LD.
Q5. What are the typical installation methods for composite pipelines?
A: Standard methods include butt-welding, flanged connections, and grooved coupling. All methods must adhere to ASME B31.3 for process piping and pass hydrostatic/leak tests as per ISO/ANSI norms.
Q6. How is quality assured during manufacturing?
A: Through in-process NDT (ultrasonic, radiography), sample cut-out metallography, hydrostatic pressure, and dimensional checks. Each pipe receives a unique code for full traceability.
Q7. Can composite pipe be used for abrasive slurry or corrosive chemicals?
A: Absolutely. Composite and Laser Clad Pipes are specially engineered for abrasive mining slurries, acidic/alkaline chemical lines, and produced water, with documented field use in copper, phosphate, and desalination projects.

Carbon Steel &stainless Steel Elbow
Elbows are pipe fittings used to change the direction of pipelines in piping systems, commonly employed at pipeline bends. They are widely used in industries such as petroleum, chemical, and power. The common size range for elbows is DN15-DN2000, and typical angles include 45°, 90°, and 180°.
Laser clad steel pipes are manufactured using laser cladding technology. This technology involves adding cladding material to the surface of ordinary steel pipe base material, using high-energy-density laser beams to fuse the cladding material with the steel pipe surface, forming a metallurgically bonded cladding layer. These pipes are generally used in compressed air energy storage projects as underground deep well transportation pipes or casings, as well as in oil, natural gas, and geothermal well extraction.
The anti-corrosion and thermal insulation products we focus on produce play a key role in the industrial pipeline system, especially the thermal insulation pipe fittings and steel pipes. Thermal insulation pipe fittings cover elbows, tees, reducers and pipe supports, with specifications ranging from DN15 to DN1800, and are made of carbon steel, alloy steel, stainless steel, bimetallic composite, nickel-based alloy and other materials.
