Non-standard ultra-thick-wall tees mainly solve the problems that standard tees and conventional thick-wall tees cannot be installed under extreme pressure, strong corrosion, high-frequency vibration, and non-standard layouts, and that they have insufficient pressure-bearing capacity and insufficient corrosion allowance. We adopt integral forging, seamless hot pressing, one-piece forming, or custom welding reinforcement processes, support full-material customization of carbon steel, stainless steel, alloy steel, and special weathering steel, and the wall thickness can be adjusted within the range of 3–60 mm according to working conditions; the branch angle, reducing ratio, and connection ports can all be custom-manufactured non-standardly according to drawings and on-site measured data. The products are often used in ultra-high-pressure auxiliary equipment pipelines of power stations, extreme process pipe networks of petrochemicals, strongly corrosive systems of coal chemicals, high-pressure special equipment of heavy industry, and old non-standard high-pressure pipe network renovation projects. Before purchasing, it is recommended to provide working condition parameters, equipment drawings, or on-site installation dimensions; we will assist in confirming the material, wall thickness, interface form, and delivery schedule.
Overview
The non-standard ultra-thick-wall tee is our customized high-strength branch pipe fitting designed for extreme working conditions. It is not restricted by the conventional wall thickness and structure of national standards or American standards; wall thickness, diameter, angle, reducing size, and connection port form can all be manufactured one-to-one according to drawings or on-site measured data. The product adopts integral forging, seamless hot pressing, one-piece molding, or customized welding reinforcement processes. The pipe wall is dense and uniform throughout, making it suitable for pipeline branch scenarios involving ultra-high-pressure extreme pressure bearing, ultra-high-temperature alternating conditions, strong corrosive wear, high-frequency impact and vibration, and the absence of standard pipe fittings that can be adapted.
Key Features
First, the wall thickness can be customized up to 60 mm, breaking through the upper limit of conventional thick walls and matching pressure-bearing and corrosion allowance according to working conditions. Second, the diameter range covers DN15–DN1200, supporting non-standard reducing sizes, non-standard branch angles, and eccentric irregular structures. Third, the materials cover carbon steel, stainless steel, alloy steel, and special weather-resistant steel, and can be adapted to ultra-high-temperature alternating conditions up to 550°C and strong acid-alkali corrosive environments. Fourth, the connection ports can be customized according to drawings with special bevels, non-standard flanges, irregular threads, or socket structures. Fifth, before leaving the factory, each product undergoes mechanical verification, wall thickness inspection, dimensional calibration, high-pressure testing, and non-destructive flaw detection to reduce on-site installation and pressure-bearing risks.
Applications
The non-standard ultra-thick-wall tee is mainly used for extreme and non-standard pipeline branches that standard thick-wall pipe fittings cannot handle. In the power sector, it can be used for ultra-high-pressure, ultra-high-temperature auxiliary main pipelines in power stations; in the petrochemical and coal chemical sectors, it can be used for process pipe networks with strongly corrosive media, high-velocity erosion, and long-cycle operation; in the heavy industry and metallurgy sectors, it can be used for connecting pipelines of high-temperature, heavy-load, and high-frequency vibration equipment; in the renovation of old plant areas, it can match legacy non-standard pipe diameters, non-standard angles, and non-standard reducing sizes to reduce overall pipe modification; in the special equipment sector, it can be used for non-standard interfaces of imported equipment, irregular layouts in narrow spaces, and high-risk branches with extreme pressure bearing.

FAQ
What is the difference between a non-standard ultra-thick-wall tee and an ordinary thick-wall tee?
Ordinary thick-wall tees are usually restricted by standard wall thickness and structure such as national standards and American standards SCH160, XXS, etc. The wall thickness, diameter, angle, reducing size, and connection port form of non-standard ultra-thick-wall tees can all be customized according to drawings or on-site measured data. The maximum wall thickness can reach 60 mm, and the diameter range covers DN15–DN1200. They mainly solve extreme and non-standard working conditions where standard pipe fittings cannot be installed, have insufficient pressure bearing, or do not have enough corrosion allowance.
What are the maximum customizable wall thickness and diameter?
The customizable wall thickness range is 3–60mm, and the customizable diameter is DN15–DN1200, supporting special reducing ratios and non-standard branch angles. The specific wall thickness and diameter need to be confirmed based on the medium, temperature, pressure, and installation space. You are welcome to contact us to provide working condition parameters so that we can assist with selection.
Can non-standard customization match old pipelines or imported equipment interfaces?
Yes. We support one-to-one replicated customization based on on-site measured data, old drawings, or imported equipment interface dimensions, reducing overall pipeline modification. Please provide the measured dimensions of the old pipeline, the interface form, or the equipment drawings, and we will assist in confirming the connection ports and installation adaptation plan.
Can it be used in high-temperature and highly corrosive working conditions?
Alloy steel and stainless steel ultra-thick customized versions can adapt to ultra-high-temperature alternating conditions within 550°C and strongly acidic and alkaline corrosive environments. The specific material grade, wall thickness, and corrosion allowance need to be confirmed based on the medium composition, concentration, temperature, and flow rate. Please contact us to provide the working condition conditions so that we can recommend a suitable configuration.
How are customized products guaranteed to meet pressure-bearing and dimensional requirements?
Before leaving the factory, each product undergoes mechanical verification, precise wall thickness inspection, dimensional calibration, high-pressure pressure testing, and non-destructive testing. We produce according to customer drawings or technical agreements, and provide the corresponding inspection records at acceptance. If it is a factory manufacturing quality defect, we support free remanufacturing or replacement.
