Product Description
Company Info
Product Description
This standard applies to seamless circular tubes and pipes(hereinafter briefly referred to as "tubes") made of unalloyed steels as listed in table 1. These tubes are predominantly used in the constructin of chemical plant, vessels, pipework and for general mechanical engineering purposes. They are designed to meet high performance requirements. Normally there are no limiting vaiues or the maximum permissible working pressure of these tubes. The permissi l working temperature shall not exceed 300. Care specified in Appendix A. )
The limits of application and other specifications given in this standard shall apply except in cases here other specifications are contained in codes of practice for specific fields of application, e. G. The Technische Regeln fur Dampfkessel (TRD) (Technical rules on steam boilers) or the Technische Regeln fur Druckbehalter (TRB)
(Technical rules on pressure vessels), AD-Merkblatter (AD Instrucation sheets).

Company Introduction:
Wuxi ZhenDa Bearing Steel Tube Company, founded in June 2004, has more than 500 existing staff, covers an area of 70, 000 square meters and annual productive capacity is 100, 000 tons. Now we are able to produce dozens of kinds of steel grades and seamless steel tubes with thousands of specifications. Wuxi Jingwei steel grating company and Wuxi very steel business trading Co., Ltd are under its administration.
The products have been registered as "Hao Ren" and "zhenda", and got the Jiang Su Famous Trademark in 2004. Seamless high pressure boiler steel tube was honored the title of "Gold Cup" by the National Steel Industrial Association for its good quality. In March, 2005 we became the director unit of the National Association of Pipe Unit. Besides, in 2007, we got the award for Jiangsu famous-brand products. Our company is often regarded as the excellent supplier by our customers, and our products are of good quality which is advanced at home and abroad.
We possess a complete set of steel tube manufacturing equipments, including a set of Φ 50 strengthening piercing machines, three sets of Φ 50 piercing machine, twenty-four sets of drawing machines ranging from 15t to 100t, three heat treatment furnaces, eight sets of straightening machines with big, small and medium size and etc. In order to ensure to meet customers′ quality requirements, Our company has quite perfect testing tools, namely, three sets of eddy current flaw detection equipment, one piece of ultrasonic flaw detection equipment, one WE-600A all-purpose hydraulic test machine, one set of CHT4106(1000KN) microcomputer hydraulic testing machine for all-purpose, one set of GB-300B impact testing machine, one set of straightness spectrometers imported from Germany, and a full set of metallographic test equipment and physical and chemical apparatus. By now, we have established and enhanced a complete set of the testing means which meets the requirements.
Our company has got the special equipment (pressure pipe components) manufacturing permit issued by the AQSIQ. We have passed ISO9001Quality Management System Certification, ISO14001environmental management system certification, and the EU PED Directive (97/23 / EC), AD-2000 W0 certificate issued by Germany TUV. Our main product lines are: The seamless steel tubes for structural purposes, liquid service, high pressure boiler, low and medium pressure boiler, petroleum cracking, high pressure chemical fertilizer equipments, high carbon-chromium bearing steel tubes, cold-drawn or cold-rolled precision seamless steel tubes, cold-drawn shaped seamless tubes; ASME, JIS, DIN series seamless steel tubes, seamless steel tubes for engineering machinery fittings and various alloy steel tubes. We specialize in the field car parts(S45C/37Mn5), petrochemical industry, engineering industry, It is a professional enterprise which produces cold-drawn seamless steel tube.
