Large-diameter thick-walled seamless steel pipes, produced through advanced processes like hot piercing and heat treatment, offer exceptional strength and reliability. International grades from EN (cth., 34CrMo4) and ASTM (cth., A519 4140) alongside GB standards meet diverse needs, from hydraulic cylinders to energy infrastructure, ensuring performance under high pressure and stress.
For high-pressure hydraulic cylinders, seamless steel pipes such as ST52 (E355), SAE 4140 (42CrMo), 37Mn, and 34CrMo4 are widely used, adhering to standards like DIN 2391, ASTM A519, and GB 18248. These grades offer the necessary strength, keliatan, and precision to ensure safety and performance under extreme pressures. Selection depends on specific pressure requirements, environmental conditions, and manufacturing processes like honing or heat treatment.
The welding of UNS N08825 pipelines demands a holistic approach integrating material science, process engineering, and stringent quality control. By optimizing TIG/MIG/SMAW parameters, mitigating defects through pre/post-weld treatments, and adhering to international standards, industries can leverage the alloy’s full potential in corrosive and high-temperature environments. Continuous advancements in welding technologies promise enhanced efficiency and reliability for future applications.
Welding Inconel 625 and P22 requires meticulous control of thermal gradients, filler selection, and post-weld treatments to address metallurgical incompatibilities. Industry standards and advanced processes (cth., EMB, kimpalan laser) enhance joint reliability in critical applications. Continuous innovation in welding technology will further optimize these dissimilar joints for extreme environments.

When selecting between seamless and welded high nickel alloy pipes, consider factors such as pressure requirements, rintangan kakisan, cost, and size availability to ensure that you choose the right type of pipe for your project. For more information or assistance in selecting the right pipe, consult with a materials specialist or supplier who can help guide you through the decision-making process.
Paip ERW BLACK. Rintangan Elektrik Dikimpal (ERW) Paip dihasilkan daripada Gegelung Gelek Panas / Celah. Semua gegelung yang masuk disahkan berdasarkan sijil ujian yang diterima daripada kilang keluli untuk sifat kimia dan mekanikalnya. Paip ERW dibentuk sejuk menjadi bentuk silinder, tidak berbentuk panas.
Paip lancar dihasilkan dengan menyemperit logam ke panjang yang dikehendaki; oleh itu paip ERW mempunyai sambungan dikimpal pada keratan rentasnya, manakala paip lancar tidak mempunyai sebarang sambungan pada keratan rentasnya sepanjang panjangnya. Dalam paip lancar, tiada kimpalan atau sambungan dan dihasilkan daripada bilet bulat pepejal.
Paip lancar keluli karbon digunakan dalam pelbagai aplikasi dalam semua industri yang berbeza, termasuk petrokimia, alam sekitar, tenaga, dan banyak lagi. Terima kasih kepada lebih daripada 100 tahun pengalaman gabungan dan pengetahuan luas merentasi pelbagai industri, kami boleh membantu memadankan anda dengan produk yang sesuai untuk aplikasi unik anda. Kami mesra, wakil perkhidmatan pelanggan yang berpengetahuan akan mendengar keperluan anda dan boleh menawarkan cadangan untuk mendapatkan produk yang memenuhi keperluan anda.
