Corrosion-Resistant Pipes

Brief Version

Industries including petrochemical, marine engineering, pharmaceutical and environmental protection often face pipeline failure issues when conveying acid, alkali and salt water media. Corrosion inside pipes triggers leakage, halts production and brings hidden safety hazards. Our corrosion-resistant pipes effectively solve these troubles with strong anti-corrosion performance, long service lifespan and flexible customized options. We implement strict full-flow control covering raw material selection, manufacturing processing and finished product inspection. The pipes can resist damage caused by harsh working conditions such as acid-base fluid, salt fog, high temperature and high pressure. Four main product series are available: stainless steel pipe, fiberglass pipe, plastic-lined pipe and bimetallic composite pipe, matching different medium corrosivity levels. Advanced forming and lining processes guarantee stable internal quality, and optimized socket sealing joints avoid common leakage risks. The products feature easy installation and extended service life, with customizable outer anti-corrosion coatings like 3PE to adapt to coastal, desert and humid environments.

Corrosion-Resistant Pipes

Industry Pain Points & Product Advantages

Core industries such as petrochemicals, marine engineering, pharmaceuticals and environmental protection need to transport corrosive liquid and gas including acid, alkali and salt water. Ordinary pipelines easily suffer internal corrosion which leads to medium leakage, production shutdown and safety accidents. Our corrosion-resistant pipes perfectly resolve these problems, featuring outstanding anti-corrosion capability, long service life and fully customizable specifications. Every link from raw material procurement, production processing to finished product testing follows strict standards, enabling stable operation under harsh environments including acid-base media, salt spray, high temperature and high pressure.

Four Main Product Series

Stainless steel pipe 316L stainless steel pipe contains 2% to 3% molybdenum element, its anti-corrosion performance reaches three times that of regular 304 stainless steel. Suitable for offshore oil delivery pipelines and chemical reactor feeding pipes, resistant to seawater, acetic acid and sulfuric acid erosion.

Fiberglass pipe Lightweight, uniform anti-corrosion layer, ideal for long-distance medium transportation in mild corrosive working conditions.

Plastic-lined pipe Adopts high-temperature rotational molding technology. Polyethylene inner lining tightly adheres to steel pipe inner wall without bubbles or wrinkles, lining uniformity exceeds 98%.

Bimetallic composite pipe Outer layer Q345B carbon steel provides structural strength and pressure resistance; inner layer uses high anti-corrosion alloy such as Hastelloy or titanium alloy. Two layers are combined via explosive cladding or hot rolling, bonding strength above 200MPa. It cuts the high cost of full alloy pipes while solving carbon steel corrosion problems, with excellent cost performance for highly corrosive complex working conditions.

Mature Production & Connection Technology

Precise material inspection: Stainless steel plates are tested with spectrometers to guarantee qualified alloy element content. Stable lining craft: Plastic-lined pipes adopt rotational molding to eliminate lining detachment defects. Optimized sealing structure: Socket-type connection with dedicated anti-corrosion sealing rings, effectively avoiding leakage defects of traditional flange connections.

Installation & Customization Support

Standardized pipe interfaces and matched special installation tools speed up field construction compared with conventional pipes. Long-term cost advantages come from extended service life. Custom surface treatment solutions are supported, including hot dip galvanizing, plastic coating and 3PE anti-corrosion coating, adapting to desert, coastal and humid service environments.

Wide Application Scenarios

Petrochemical industry: Transport crude oil, acid alkali solvent and liquefied petroleum gas to sustain continuous refining production. Marine engineering: Seawater desalination equipment and subsea oil pipelines resist long-term seawater corrosion. Environmental protection industry: Discharge pipeline for industrial wastewater and sewage with high-concentration corrosive pollutants. Other applicable fields: Metallurgy, food processing, nuclear power industry, serving as core medium conveying equipment.
