MS106 Gr.B Coating Tube Internal Cement Lined & External Reinforced Bitumen Enamel Wrapping
Detailed Specifications & Characteristics
1. Base Pipe
Standard Specification: MS106 Gr.B
Interpretation: Typically refers to seamless or welded steel pipe complying with an international or industry material standard (such as ASTM A106 Gr.B or equivalent). This grade offers excellent mechanical strength and toughness.
Size Range: Available in various diameters (DN/NPS), wall thicknesses, and lengths to meet project requirements.
2. Internal Coating: Cement Mortar Lining
Purpose & Function:
Corrosion Protection: Creates a high-pH environment that passivates the internal steel surface, preventing rust.
Water Quality Assurance: Non-toxic and odorless, complying with potable water hygiene standards, preventing secondary contamination.
Hydraulic Performance: A smooth surface reduces friction loss, improves flow efficiency, and lowers long-term pumping energy costs.
Scale Inhibition: Minimizes the adherence of scale and deposits, simplifying maintenance and cleaning.
Process Features:
Applied via centrifugal spinning or mechanical spraying to ensure a uniform, dense, and firmly bonded lining.
Lining thickness conforms to standard requirements based on pipe diameter (e.g., 3mm - 8mm).
Properly cured after application to achieve specified hardness and prevent cracking or spalling.
3. External Coating: Reinforced Bitumen Enamel Wrapping
Coating Structure (From inside out):
Primer Layer: A high-performance modified bitumen primer provides excellent adhesion to the blast-cleaned steel surface.
Anti-Corrosion Layer: A thick layer of hot-applied bitumen enamel serves as the primary barrier, offering high electrical resistance and chemical inertness.
Reinforcement Layer: A glass fiber or organic fiber mat is tightly wrapped into the hot enamel. This key reinforcement significantly enhances mechanical strength, providing resistance to impact, abrasion, and soil stress, preventing damage during handling, transport, and installation.
Protective Wrap: An outer wrap (e.g., kraft paper or plastic film) protects the coating from UV degradation and physical damage until installation.
Galvanized vs. Pre-Galvanized Steel: Key Differences Explained
When selecting steel products such as pipes or sheets, it’s essential to distinguish between galvanized and pre-galvanized options to balance performance, longevity, and cost.
●Superior Protection, Longer Lifespan: Our industry-leading dual-protection technology (cement mortar lining + reinforced bitumen enamel coating) ensures exceptional corrosion resistance and physical durability even in harsh environments, significantly extending the pipeline system's service life and reducing lifecycle costs.
●Stable Quality, Safe and Reliable: From raw materials to finished products, we implement strict quality control systems (e.g., international standards like AWWA C205), guaranteeing excellent mechanical performance and defect-free coating protection for secure water supply.
●Professional Expertise, Value Delivery: With extensive industry experience and technical knowledge, we provide not only high-quality products but also professional technical support and solutions to ensure smooth project execution and deliver greater value.
Application Of 3PP/3PE Steel Pipe
3PP/3PE coated steel pipes, particularly spiral welded pipes, are primarily utilized in industries requiring robust corrosion protection and thermal resistance. These pipes are engineered for the transportation of high-temperature media and are extensively employed in pipeline infrastructure projects within high-temperature environments, such as desert regions characterized by elevated surface temperatures and prolonged solar exposure.
Key industrial applications include:
●Oil and Gas Transmission – Buried pipelines for crude oil, refined products, and natural gas, especially in arid or high-temperature terrains.
●Water Supply Systems – Long-distance water conveyance pipelines in thermally demanding environments.
●Chemical and Process Industries – Transport of heated fluids or corrosive media where enhanced anti-corrosion and thermal stability are critical.
Complete Steel Grade For Your Square Steel Pipe
Manufacturing Standards: Complies with internationally recognized coating standards such as AWWA C205, ISO 5256, DIN 30671, or other client-specified standards.
Quality Control Checkpoints:
●Steel surface preparation (Blast cleaning to Sa 2.5, anchor profile control).
●Individual coating thickness inspection (using magnetic gauges).
●Holiday (pinhole) detection using high-voltage spark testers.
●Adhesion tests.
●Visual inspection.
