Descrição
Commercially pure titanium welding fitting
Grau de titânio 2 Tampa final do tubo
A lightweight corrosion-resistant butt-weld closure for seawater, dessalinização, químico, pulp-and-paper and heat-transfer systems.
What is a Titanium Grade 2 tampa da extremidade do tubo?
A Titanium Grade 2 pipe end cap is a factory-made unalloyed titanium welding fitting used to close the end of a pipe. ASTM B363 covers seamless and welded titanium and titanium-alloy welding fittings, incluindo bonés.
UNS R50400 is commercially pure titanium with moderate strength, good formability and weldability. Its protective oxide film gives excellent performance in many seawater and chloride-bearing environments. Titanium is not universally resistant: fluoride media, strong reducing acids and anhydrous chlorine require particular caution.

ASME B16.9 e opções de fornecimento MSS SP-43
ASME B16.9
ASME B16.9 may be used as the ordered dimensional basis for Grade 2 titanium butt-welding caps, com ASTM B363 controlling material and manufacturing requirements.
MSS SP-43
MSS SP-43 dimensions may be specified for applicable corrosion-resistant fitting service when permitted by the design. Confirm wall matching and pressure-design basis.
Grau de titânio 2 vs 316L pipe end cap
| Ponto de seleção | Grau de titânio 2 / R50400 | 316eu / S31603 |
|---|---|---|
| Densidade | Baixo, aproximadamente 60% of stainless steel density | Higher density and familiar fabrication |
| Seawater behavior | Excellent in many aerated seawater/chloride systems | May be vulnerable to localized corrosion in demanding chlorides |
| Controle de fabricação | Requires excellent shielding and contamination control | Well-established stainless welding practice |
| Cost basis | Higher initial cost but strong lifecycle potential | Lower initial cost and broad availability |
Aplicações típicas
| Indústria | Serviço típico | Motivo da seleção |
|---|---|---|
| Dessalinização | Seawater transport, RO auxiliaries and brine systems | Chloride corrosion resistance and low lifecycle maintenance |
| Marinho / offshore | Seawater cooling and platform utility systems | Low weight and resistance to seawater |
| Processamento químico | Oxidizing chloride, nitric acid and wet chlorine duties where compatible | Stable protective oxide film |
| Celulose e papel | Chloride-containing bleaching support systems | Resistance in selected bleaching environments |
Exemplos de aplicação não são uma aprovação de projeto. O engenheiro de materiais de tubulação deve confirmar a compatibilidade com corrosão, temperatura, pressão, procedimento de soldagem e requisitos de código aplicáveis.
Fabricação, inspeção e EN 10204 documentação
Titanium caps require strict cleanliness during forming and welding. Iron contamination, umidade, grease and inadequate inert-gas shielding can damage weld quality. Inspection requirements should include surface condition and fabrication controls appropriate to titanium.
Nota 2 química, mechanical data and heat traceability linked to the fitting.
PMI or alloy-verification method agreed for commercially pure titanium.
DE, comprimento, parede, ovality and BE geometry checked against the order.
Surface contamination control plus PT, RT/UT or third-party inspection as specified.

Perguntas frequentes
Which ASTM standard covers Titanium Grade 2 tampas de tubos?
ASTM B363 covers seamless and welded unalloyed titanium and titanium-alloy welding fittings, incluindo bonés. Nota 2 corresponds to UNS R50400.
What is the European material number for Grade 2 titânio?
The commonly referenced Werkstoff number is 3.7035. The purchase order should still identify ASTM B363 Nota 2 e UNS R50400 when that is the governing basis.
Is Grade 2 titanium suitable for seawater?
It performs very well in many aerated seawater and chloride systems, but every design must consider temperature, fendas, depósitos, fluxo, galvanic coupling and contaminants.
Why must titanium welding be kept clean?
Heated titanium reacts readily with oxygen, nitrogen and hydrogen. Clean surfaces and effective inert-gas shielding are essential to avoid embrittlement and contaminated welds.
Are heavy-wall titanium caps available?
They can be manufactured in selected sizes, but availability depends on starting material, forming strain, tratamento térmico, exact wall and quantity. Submit pipe dimensions for review.
