Yangzhou Chengde (YC) is one of the best steel pipe manufacturers in the world, and the production diameter from 8" to 48" in OD and wall thickness from 9.53 mm up to 140mm. We can produce the boiler steel pipe and thermal power steel pipe according to the ASTM A335 and ASME SA335 standards. In recently 10 years, we have been exported about 300000 tons P11, P12, P22, P91, P92 P5, P9 and P36 steel pipe to India, Japan, Korea, South East Asia, Middle East, North America and Europe.

In the year of 2015, we win the first prize of National Science and Technology Progress Award by the program of [The innovative research & development, and application of steel pipes used in 600 ℃ Ultra-super critical coal power generation unit".

Yangzhou Chengde is continuously strengthening the technical innovation, together with Bao steel and other companies. Yangzhou Chengde has spent 10 years on the R&D of the steel pipe used in 600 ℃ Ultra-super critical coal power generation unit and achieved the tremendous success on realizing the manufacture of such high-end seamless steel pipe from zero to the advance level, which has filled up the vacancy in China and broken up the foreign technological monopoly. The steel pipe manufacturing technology of China has leaped to the international advanced level and further confirmed the leading position of Chinese companies in researching and making high-end special steel pipes.

YANGZHOU CHENGDE STEEL PIPE CO.,LTD

CHENGDE Group was founded in 1988, and has been growing to a leading large diameter seamless pipe manufacturer with production range 8``-48`` in OD and wall thickness from 9.53 mm up to 140mm. CHENGDE is a joint venture with American PCC Group (Precision Castparts Corp. Fortune 500 enterprises of USA, PCC is the world leader in structural investment castings, forged components, and airfoil castings for aircraft engines and industrial gas turbines. Airbus, Boeing, GE, Rolls-Royce, and many other leading manufacturers depend on us for critical airframe, engine, power generation, medical, and general industrial components. With few exceptions, every aircraft in the sky flies with parts made by PCC). Chengde is fully integrated with PCC`s quality and management system, using the advance management tools like TOC to control the production and manage the key performance indexes. CHENGDE`s seamless steel pipes are supplies to Middle/Down-stream, Coal power generation, Nuclear power, Mechanical, shipyard and Gas cylinder applications. YC is the approved vendor of well-known EPC companies and oil companies such as Exxon/Shell/Alstom/Fluor/Bechtel/Siemen/SNC Lavalin/Kiewit/Keppel/Petrobras. CHENGDE`s pipe production follows the aerospace standards with the JV background with PCC, especially for heat treatment, the furnaces are calibrated to Aerospace AMS-2750 standard. The whole production process CHENGDE has been granted a number of approval certificate by international institutions, such as Nuclear pipe certificate, 914mm Cylinder certificate, API monogram and certificate, ISO9001 by TUV NORD, ISO14001/OHSAS18001 by CQC, approvals from Shipping Classification Bureaus like DNV, RINA, ABS, Lloyd, GL, Bureau Veritas, and permit of exporting to Europe as PED 97/23/EC and AD 2000 certificates for pressure pipes, CPD (Construction Products Directive), etc. Nuclear pipe certificate is the strictest in the industry and CHENGDE is the first private company with nuclear certificate in China, which proved the highest quality level in China pipe industry. 2. Unique Piercing-Rolling-Reeling mill technologies Chengde invented the Piercing-Rolling joint production technologies with its own patents and intellectual properties. The process is unique from others with following edges: 1) Stable, fast and continuous 2) Flexible on non-standard sizes 3) Swift tooling switching 4) Uniform mechanical properties and dimensions in longitudinal& transversal directions 5) Better surface condition thanks to shorter rolling time & good tooling quality 6) Three-roller/five racks sizing machine can avoid inner hexagon significantly 3. Low Cost and Competitive Pricing Patented Piercing-Rolling-Reeling process and other assistive facilities (such as continuous heating furnace, hot expansion mill, 850 sizing mill, reeling mill, five racks sizing mill, etc.) formed a continuous product line. Reasonable product line saved energy and improved material yield to ensure CHENGDE have a lower production cost and short production cycle. Raw material is supplied by top steel mill in China, such as XINGCHENG Steel, BAO Steel and so on. Local billet availability provide the economic material cost and quick delivery. 4 Quick and On-time Delivery Quick and On-time Delivery assured by Patented and advanced devices. Carbon steel pipe and low alloy steel pipe can delivery in 45~60 days, high alloy steel pipe such as P91 P92 can delivery in 75~90 days. If customers require more quickly delivery, CHENGDE will try us best to satisfy the delivery. CHENGDE has an extensive expediting department to provide support for its customers project management teams.
