Buttwelded Caps
Timex Metals is a leading Buttwelded Caps Manufacturer, offering premium-grade pipe-end sealing solutions designed for leak-proof performance and structural reliability. Our buttwelded caps are available in various types, including hemispherical, elliptical, flat-end, and conical forms, each engineered to meet specific pressure ratings and operational requirements. Manufactured using stainless steel, carbon steel, alloy steel, and mild steel, these caps offer excellent durability, corrosion resistance, and mechanical strength. With surface finishes such as pickled or electropolished, they are ideal for hygienic environments across pharmaceutical, biotech, food processing, and chemical industries.
Material and Grades Table – Buttwelded Caps
| Material / Grade | Standard Sizes (inch) | Weight per Meter (kg/m) | Notes / Applications |
|---|---|---|---|
| Carbon Steel (CS) | 1/2" – 24" | 0.9 – 12.5 | High strength, commonly used in general piping and industrial applications |
| Stainless Steel SS 304 | 1/2" – 24" | 0.85 – 12.0 | Corrosion-resistant, suitable for sanitary and chemical applications |
| Stainless Steel SS 316 | 1/2" – 24" | 0.9 – 12.3 | Excellent corrosion resistance, ideal for harsh chemical and marine environments |
| Alloy Steel (AS) | 1/2" – 20" | 1.0 – 11.5 | High durability and temperature resistance for critical industrial systems |
| Duplex Stainless Steel 2205 | 1/2" – 12" | 1.1 – 10.0 | High strength and superior corrosion resistance in aggressive process environments |
Buttwelded caps visually close off the pipe ends in the different industrial systems and thus, are the devices that make the system leak-proof and safe. The selection of the suitable material and the grade of the same is what makes the product long-lasting, resistant to corrosion, and efficient in operations. By using this table buyers can get the proper products quickly through a B2B portal for Aluminium Fin Tube and the like applications.
