Applications of titanium end caps
Titanium end caps are widely used in industrial systems where sealing, corrosion resistance, and strength are critical. They can block the flow of liquids or gases while withstanding both external corrosion and internal media attack. Common applications include:
- Wellhead equipment, pipeline sealing, and high-pressure anti-corrosion systems in oil and gas.
- Acid and alkali-resistant fluid systems and pressure vessel closures in chemical and petrochemical industries.
- Sterile transfer lines and end protection for pure water or steam pipes in pharmaceutical and medical systems.
- Liquid processing tanks and pipeline seals in food and brewing to prevent contamination.
- End seals and anti-corrosion plugs in brine systems for seawater desalination.
- High-temperature exhausts and pressure-sealing closures in aerospace and defense sectors.
- Heat exchangers, steam pipelines, and condensate system closures in power generation and energy equipment.
Case study: titanium end caps for high-pressure anti-corrosion sealing in oil and gas systems
A major oil and gas equipment manufacturer in the Middle East required wellhead components and pipeline accessories for field development.
The working conditions included high pressure, high salinity, and H₂S corrosion. The end caps needed to meet strict standards for strength and extreme corrosion resistance.
- Maintained 25 MPa pressure long-term with no deformation or leakage
- Operated for 18 months in high-sulfur environments without signs of corrosion
- Seamlessly integrated with the customer's existing ASME B16.9 fitting system
Client feedback:
"These titanium end caps perform reliably under high temperature, high pressure, and high salinity. They are our go-to solution for sealing natural gas wellheads."
Titanium end caps manufacturing process
We produce seamless titanium end caps using cold forming technology to ensure precise dimensions, stable structure, and excellent weldability. The main steps include:
- Incoming inspection: Verify titanium grade and dimensions to meet required standards.
- Cutting: Slice raw materials into specified round blanks.
- Cold forming: Shape the end caps via spinning or die pressing.
- Heat treatment: Anneal to relieve stress and enhance strength and toughness.
- Sandblasting: Remove oxide layers and improve surface cleanliness.
- Beveling: Prepare weld grooves for tight, secure joints.
- Surface treatment: Optional pickling, passivation, or protective coating application.

Frequently asked questions (FAQ)
What is an end cap?
An end cap is a pipe closure fitting installed at the end of a pipe or vessel. It seals the opening to prevent media leakage or contamination.
Titanium end caps offer outstanding corrosion resistance, making them ideal for demanding environments.
What types of titanium end caps are available?
We provide a variety of titanium end cap designs, including hemispherical, elliptical, conical, dished, flat, and threaded types—each suited for different pressure and structural needs.
How do I determine the right end cap size?
You'll need to select based on the pipe's nominal size (NPS), wall thickness (SCH), and connection type (welded or threaded).
We offer technical support and drawings to ensure a perfect fit. Quick Quote
Can titanium end caps be welded? How is the weldability?
Yes. Titanium end caps, especially those made of Grade 2 or Grade 5, offer excellent weldability. After beveling, they form seamless, strong, and corrosion-resistant joints with titanium pipes.
Can titanium exhaust pipes be bent?
Yes. Grade 2 and Grade 5 titanium pipes have good ductility and heat resistance, and can be cold- or hot-bent using proper equipment—ideal for custom exhaust systems.
Are titanium pipes safe?
Absolutely. Titanium pipes are strong, corrosion-resistant, and non-toxic. They are widely used in chemical, pharmaceutical, and food industries as a safe and reliable material choice.
