To make sure the highest quality possible, each test is carried out strictly with our in-house testing facilities. The most generally used methods of testing given below:
Chemical analysis by Spectrometer
Mechanical tests in Normal and High temperature.
Ultrasonic, X-ray, Dye Penetrant Test.
Boroscope; Eddy current testing; Microscope; Pressure tests.
Founded in 1996, our company has been developing all the way. Now we have 400 employees, 80 intermediate and senior technicians, covering an area of 100, 000 square meters including building area 45, 000 square meters, with fixed asset approximately 80 million, diverse instruments over 200 sets. It is our most important task to improve product quality and internal management. In possession of a complete set of quality assurance and management system, we are qualified by ISO9001 quality system in 1991.
With sound procedure from melting, casting, machining, welding, testing to ex-factory, and complete quality assurance system, we have established long-term collaborative relationship with scientific research unit, institute, design department and clients, enjoying broad reputation, being praised as 'Contract Abiding Enterprise 'by National Industrial and Commercial Bureau.
We have import and export authority of self-operating and acting for diverse merchandises and technologies, with operating scope as follows: Complete equipment for industrial furnace: Hi-temp. Alloy furnace tube, reforming tube, cracking tube, radiant tube, glass roll, hearth roll, special steel manifold, and pigtail pipe; Wear resisting piping: Wear resisting steel straight tube, elbow, and tee piece; Static casting: Fittings, hook, bracket, socket, brick bracket, blind pot, and other heat resistant steel casting; Precise casting: Pressure contained elbow, tee piece and tray.
High speed CPC steel rolling project, with broad prospect, featuring advantages of wear resistance, small structure, heat fatigue resistance, serving life 3 times than that of original roll, are widely used for rolling line of steel plate and pipe in metallurgical enterprises, making up the domestic blank of high-speed compound steel roll. It is a national '863' scientific-research product.
Service objective, quality first, client superior, quality principle, clients' need is what we pursue, and to furnish clients with quality products and service are our permanent pursuits.
Making progress with times and excellent developing environment contributes to our vast developing space. Zhengxiang will insist on personnel base and make endeavor to create more splendid future.
