OIL AND GAS: SEAMLESS PIPING FOR HIGH PRESSURE AND SOUR SERVICE
Oil and gas systems combine high pressure, chloride-rich produced water, and CO₂ and H₂S in the same line. Choosing the wrong pipe material can lead to pitting, stress corrosion cracking and unplanned shutdowns. This guide explains which stainless steel, duplex and nickel alloy pipes are used in upstream, midstream and offshore projects, and how to choose between them.
CHEMICAL & PETROCHEMICAL: ENGINEERED FOR EXTREME CORROSION RESISTANCE
Chemical plants handle sulfuric, hydrochloric, phosphoric and nitric acids, caustics, chlorides and organic solvents, often at high temperature and pressure. A pipe that performs well in one medium can fail quickly in another, so selection has to be based on the actual process conditions. This guide summarizes how stainless steel, duplex and nickel alloy pipes are matched to common chemical services.
POWER GENERATION: UNINTERRUPTED ENERGY FOR GLOBAL INFRASTRUCTURE
Power plants push materials hard: steam at high temperature and pressure, cyclic loading, fireside corrosion and, in nuclear plants, radiation and high-purity water chemistry. This guide covers the heat-resistant stainless steel and nickel alloy pipes and tubes used in thermal, nuclear and emerging advanced power systems.
PULP & PAPER: RELIABLE PERFORMANCE IN CORROSIVE PROCESS STREAMS
Pulp and paper mills run some of the most chemically varied processes in heavy industry: hot alkaline cooking liquors, chlorine-based or oxygen-based bleaching chemicals, sulfur compounds and acidic condensates. This article explains where duplex 2205, 317L, 904L, 6Mo and nickel alloy pipes are used in a modern mill and why.
AEROSPACE: ADVANCED ALLOYS FOR HIGH-STRENGTH APPLICATIONS
Aircraft engines, exhaust systems and space propulsion expose metals to extreme temperature, vibration and corrosion while weight must be kept to a minimum. Nickel-based superalloys keep their strength and oxidation resistance where stainless steels and aluminum cannot. This article explains the main nickel alloy tube grades used in aerospace and what buyers should specify.
FOOD, BEVERAGE & PHARMA: PURITY-FOCUSED HYGIENIC SOLUTIONS
In food, beverage and pharmaceutical production, the pipe surface touches the product. Materials must be corrosion resistant, smooth, easy to clean and non-contaminating. Sanitary stainless steel tubing in grades 304 and 316L is the global standard for these industries. This guide explains the grades, surface finishes and standards buyers should specify.
MARINE & DESALINATION: STRUCTURAL STABILITY IN HARSH MARINE ENVIRONMENTS
Seawater contains about 19,000 mg/L of chloride, making it one of the most aggressive natural environments for metals. Standard 304 and 316 stainless steels often suffer pitting and crevice corrosion in seawater service. This article explains which seawater-resistant stainless steel, super duplex and nickel alloy pipes are used for offshore platforms, ships and desalination plants.
HEAT EXCHANGER & BOILER: ENHANCED THERMAL EFFICIENCY AND DURABILITY
Heat exchangers, condensers and boilers depend on thousands of thin-walled tubes transferring heat reliably for decades. A single leaking tube can shut down a unit or contaminate a process. This guide explains how to choose stainless steel, duplex and nickel alloy heat exchanger tubes and which standards to specify.
ENVIRONMENTAL & FGD: CORROSION PROTECTION FOR SCRUBBER SYSTEMS
Environmental systems, especially wet flue gas desulfurization (FGD) scrubbers, create highly corrosive conditions: acidic condensate, high chloride concentrations, abrasive limestone slurry and temperature swings. This article explains how duplex stainless steel and nickel alloy pipes are selected for FGD and other environmental protection applications.
CONSTRUCTION & ARCHITECTURE: DURABLE SOLUTIONS FOR MODERN STRUCTURES
Stainless steel pipe and tube appear in modern buildings, bridges and public spaces as handrails, curtain wall supports, canopies, façades, water supply systems and structural members. Designers choose it for a clean appearance, long life and low maintenance. This guide explains which stainless steel and duplex pipe grades suit different construction environments, finishes and standards.
AUTOMOTIVE EXHAUST: HEAT-RESISTANT TUBING FOR EMISSION SYSTEMS
Exhaust systems face a demanding mix of heat, thermal cycling, road salt and acidic condensate. Stainless steel tubing became the standard material for automotive exhaust because it resists corrosion and oxidation for the life of the vehicle. This guide explains which stainless steel and nickel alloy tubes are used in automotive and transportation applications, and how to specify them.
NEW ENERGY: PIPING FOR HYDROGEN, LNG AND CSP APPLICATIONS
The energy transition is creating demand for piping that can handle hydrogen at high pressure, liquefied natural gas at −162 °C, and molten salt at around 565 °C. Each condition places different demands on the material. This article explains which stainless steel and nickel alloy pipes and tubes are used in hydrogen, LNG and concentrated solar power (CSP) projects.
