Peredam Konsentris Stainless: Dilas dan Seamless – ASME B 16.9
PIPA FITTING are critical elements in plumbing and oil industries. Mereka berfungsi sebagai 'jaringan ikat’ yang menghubungkan berbagai komponen suatu sistem, memastikan aliran cairan lancar dan efisien. Diantara perlengkapan tersebut, the stainless concentric reducer stands out due to its unique geometry and design. It is an essential tool in pipe systems, used to connect two pipes with different diameters. The stainless concentric reducer comes in two types: Dilas dan Seamless. The American Society of Mechanical Engineers (ASME) provides the standard ASME B16.9 to define the dimensions and physical characteristics of these reducers.
Introduction to Stainless Concentric Reducers
A stainless concentric reducer, as its name suggests, is constructed from stainless steel – a corrosion-resistant material known for its durability and strength. It is composed of two pipes with different diameters, arranged so that their central axes coincide, ensuring a smooth, gradual transition from one pipe diameter to another. This gradual transition reduces turbulence and friction, which could otherwise cause wear and tear in the pipeline.
The utility of the concentric reducer is evident in various industries, from chemical to petroleum and natural gas. It is used in systems where it’s necessary to alter the diameter of the pipe while maintaining the centerline common to both the larger and smaller pipes. Lebih lanjut, stainless steel’s physical properties make it desirable for applications in harsh environments where other materials might fail due to corrosion.
Welded vs. Pereduksi konsentris yang mulus
The stainless concentric reducer is manufactured in two types: Dilas dan Seamless. The choice between these two types depends on the specific application and the performance requirements.
Welded Concentric Reducers
Welded concentric reducers are made by welding together two separate pieces of stainless steel pipe. They are usually chosen for their cost-effectiveness and are most common in Diameter Besar applications where the cost difference between seamless and welded is substantial.
The welded reducers are often preferred in industries where high pressures are not a concern. namun, they may have a lesser degree of smoothness at the joint, which could potentially lead to turbulence. This isn’t typically a significant concern though, as modern welding techniques have improved the quality and smoothness of welded joints.
Stainless Concentric reducer – Dilas
Butt welding stainless reducers are used to decrease or increase the pipeline size at a given location. With regards to the Welded Concentric reducers, ujung terbuka dari alat kelengkapan disejajarkan dan dipusatkan satu sama lain. umumnya, ukuran delta tidak melebihi 2 (max 3) ukuran untuk menghindari penurunan tekanan yang berlebihan dalam pipa (jika diperlukan beberapa kali penurunan run pipe, ini harus dilakukan secara bertahap).
Peredam Konsentris Stainless dirancang dengan diameter kecil dan besar pada ujung yang berlawanan dan disatukan dengan bagian transisi berbentuk kerucut. Tipe khusus ini dengan konstruksi yang dilas.
Pereduksi konsentris yang mulus
Pereduksi konsentris yang mulus, Di samping itu, terbuat dari sepotong baja tahan karat. Mereka diproduksi melalui proses kompleks yang disebut ekstrusi atau gambar. Metode ini melibatkan pemanasan balok baja tahan karat berbentuk silinder dan kemudian menusuknya dengan mandrel untuk membuat bentuk pipa. Peredam kemudian dipanaskan kembali dan diregangkan hingga mencapai dimensi yang diinginkan.
Peredam mulus menawarkan keuntungan dalam aplikasi tekanan tinggi karena keseragamannya dan kurangnya lapisan las, yang berpotensi menjadi titik lemah di bawah tekanan tinggi. Mereka juga memastikan transisi cairan yang lebih lancar, sehingga mengurangi turbulensi dan potensi erosi.
Stainless Concentric reducer – MULUS
Peredam konsentris stainless adalah sejenisnya pemasangan pipa yang menghubungkan dua pipa yang diameternya berbeda. Peredam pipa tahan karat tersedia dalam berbagai bahan tergantung pada penggunaan akhir produk dan alat kelengkapan ini diproduksi dalam ukuran inci dan metrik.
Peredam Konsentris digunakan untuk menyambung bagian pipa atau tabung pada sumbu yang sama. Mereka menyediakan transisi berbentuk kerucut segaris antara pipa bertekanan dengan diameter berbeda. A pipe reducer can be a single diameter change or a multiple diameter change. The pipes cannot recognize what the outside configuration of the pipe reducer looks like.
The pipe flow is affected by the inside diameter conical transition configuration which can be axially moved and externally reconfigured to provide for more economical reducer fittings. Dengan demikian, concentric reducers connect pipes of unequal size but have a common centerline. In other words, it is a type of pipe fitting with different size ends to join pipes of different diameter that joins pipe sections on the same axis.
Concentric reducers are designed with the small and large diameters on opposite ends and joined by a cone shaped transition section. They are available in both seamless and welded construction.
- Concentric reducers will transition gracefully between the piping and the pump.
- The concentric reducers help in transporting slurries or abrasive liquids.
- They are useful in services where cavitation is present.
- When transporting between flanges or pipes of different ratings and wear protection is necessary, concentric reducers are ideal.
- Concentric reducers are used in discharge of the pump.
Standar ASME B16.9
Standar ASME B16.9, provided by the American Society of Mechanical Engineers, specifies the dimensions, toleransi, Peringkat Tekanan, and markings for factory-made wrought fittings like the stainless concentric reducer. The standard ensures the compatibility and interchangeability of fittings across different manufacturers and applications.
The standard covers the overall diameter, Dinding tebal, concentricity, and surface finish of the reducer. contohnya, it defines the end-to-end dimension of the reducer and the length of the reduction section. This standardization is critical to ensure the reducer fits correctly into the system, thereby preventing leakage and maintaining the efficiency of the fluid flow.
ASME B16.9 also specifies the pressure-temperature ratings for different materials and wall thicknesses. These ratings guide the selection of a reducer for a particular application, ensuring the fitting can withstand the system’s operating conditions.
Kesimpulan
Kesimpulannya, Peredam Konsentris Stainless, whether welded or seamless, play a vital role in the fluid flow systems across various industries. Their design allows for a smooth transition in pipe diameters, reducing turbulence and increasing system efficiency. Standar ASME B16.9 memberikan pedoman yang jelas mengenai dimensi dan toleransi reduksi ini, memastikan kompatibilitas dan pertukarannya di berbagai aplikasi. Terlepas dari perbedaan antara reduksi yang dilas dan yang mulus, pilihan di antara keduanya pada akhirnya bergantung pada aplikasi spesifik dan persyaratan kinerja yang diharapkan. Terlepas dari jenisnya, reduksi ini berfungsi sebagai contoh yang sangat baik dari ilmu pengetahuan dan teknik di balik komponen sistem aliran fluida yang paling sederhana sekalipun.
