Tianrui Jinbo—Bimetallic Composite Steel Pipe Solution Provider

An industry-leading manufacturer of bimetallic composite steel pipes, with products applied in energy storage, electric power, petroleum, chemical, and other industries.

Focusing on Laser Cladding Composite Pipes to Empower Industrial Pipelines

Shanghai Tianrui Jinbo Composite Pipe Co., Ltd. was established in 2023 with a registered capital of 30 million RMB. It is a technological leader and market pioneer in the field of laser cladding bimetallic composite pipes.

In collaboration with strategic partners such as Baosteel, and relying on leading domestic cladding equipment with independent intellectual property rights and large-scale production bases, we provide safe, economical, and durable piping solutions for the energy, chemical, and offshore engineering industries. We address the pain points of traditional pipelines in extreme corrosion, high-temperature, and high-pressure conditions.

Our current cladding capabilities cover metal pipes with internal diameters ranging from 76 mm to 2,000 mm and lengths up to 12,000 mm. Our independently developed and produced laser cladding system can complete laser cladding layers for internal bores up to 12,000 mm long, achieving a dilution rate of ≤5% and a small heat-affected zone. This system maintains the mechanical properties of the original base material and ensures a defect-free surface upon inspection, meeting the requirements for applications in harsh anti-corrosion environments.

Having passed Baosteel’s rigorous supplier qualification audit, the company has a monthly cladding processing capacity of over 6,000 square meters. We participate in the formulation of national and industry standards and possess full-chain advantages from technical R to large-scale delivery.

Core Products

We focus on providing high-performance pipe solutions for the energy and chemical industries.

Energy Storage Pipes

Application Scenarios: High-pressure air transmission pipelines and wellbores for large-scale Compressed Air Energy Storage (CAES) systems, especially in salt cavern storage scenarios with complex geological conditions.
Core Pain Points: Pipelines face severe challenges from underground brine corrosion, pulsation fatigue caused by frequent high-pressure charging and discharging, and the need for long-term high-pressure sealing integrity. Traditional coatings or linings are prone to peeling or failure under high-pressure cycling.

Boiler Tubes

Application Scenarios: High-temperature heating surfaces (such as water walls and superheaters) of power station boilers burning low-quality fuels like high-alkali and high-chlorine coal from Xinjiang.
Core Pain Points: High levels of alkali metals and chlorine in the fuel generate low-melting-point complex sulfates and chloride vapors during combustion. This causes severe high-temperature chlorine and alkali metal corrosion on the tube walls, leading to rapid thinning and tube bursts.

Line Pipes

Application Scenarios: Onshore and offshore oil and gas gathering and trunk pipelines transporting fluids containing corrosive media (such as H₂S, CO₂, and chloride ions).
Core Pain Points: Internal pipe walls face threats of uniform corrosion, localized pitting, and stress corrosion cracking. Ordinary steel pipes are not corrosion-resistant, while solid alloy pipes are too costly; mechanical composite pipes carry potential risks of interface failure under pressure and bending stress.
