Commercially pure titanium welding fitting
Kelas Titanium 2 Tutup Ujung Pipa
A lightweight corrosion-resistant butt-weld closure for seawater, desalinasi, kimia, pulp-and-paper and heat-transfer systems.
What is a Titanium Grade 2 tutup ujung pipa?
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, termasuk topi.
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 dan opsi pasokan MSS SP-43
ASME B16.9
ASME B16.9 may be used as the ordered dimensional basis for Grade 2 titanium butt-welding caps, dengan 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.
Kelas Titanium 2 vs 316L pipe end cap
| Titik seleksi | Kelas Titanium 2 / R50400 | 316L / S31603 |
|---|---|---|
| Kepadatan | Rendah, sekitar 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 |
| Kontrol fabrikasi | 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 |
Aplikasi yang umum
| Industri | Layanan khas | Alasan pemilihan |
|---|---|---|
| Desalinasi | Seawater transport, RO auxiliaries and brine systems | Chloride corrosion resistance and low lifecycle maintenance |
| Laut / di lepas pantai | Seawater cooling and platform utility systems | Low weight and resistance to seawater |
| Pemrosesan kimia | Oxidizing chloride, nitric acid and wet chlorine duties where compatible | Stable protective oxide film |
| Pulp dan kertas | Chloride-containing bleaching support systems | Resistance in selected bleaching environments |
Contoh penerapan bukan merupakan persetujuan desain. Insinyur material perpipaan harus memastikan kompatibilitas korosi, suhu, tekanan, prosedur pengelasan dan persyaratan kode yang berlaku.
Manufaktur, inspeksi dan EN 10204 dokumentasi
Titanium caps require strict cleanliness during forming and welding. Iron contamination, kelembaban, grease and inadequate inert-gas shielding can damage weld quality. Inspection requirements should include surface condition and fabrication controls appropriate to titanium.
Nilai 2 kimia, mechanical data and heat traceability linked to the fitting.
PMI or alloy-verification method agreed for commercially pure titanium.
DARI, panjang, dinding, ovality and BE geometry checked against the order.
Surface contamination control plus PT, RT/UT or third-party inspection as specified.

Pertanyaan yang sering diajukan
Which ASTM standard covers Titanium Grade 2 tutup pipa?
ASTM B363 covers seamless and welded unalloyed titanium and titanium-alloy welding fittings, termasuk topi. Nilai 2 corresponds to UNS R50400.
What is the European material number for Grade 2 titanium?
The commonly referenced Werkstoff number is 3.7035. The purchase order should still identify ASTM B363 Nilai 2 Dan 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, celah-celah, deposito, mengalir, 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, perlakuan panas, exact wall and quantity. Submit pipe dimensions for review.
