Complete testing and quality assurance system

We implement strict quality control and have passed ISO14001-2004 certification and military quality system certification. We are also an ASME qualified manufacturer. All the pressure vessels are ASME and CE approved.

Product quality has our prior attention and the quality control department is important in the entire structure of the company. In raw material testing and production process, we are more restrictive than Chinese national standards. We adopt visual, NDT, chemical-physical and pressure testing methods in the detection. Every welding seam undergoes rigorous inspection test, and the vacuum degree surpasses that of most competitor products.

Our test center has several world-leading detection devices: helium mass spectrometer leak detector, impact testing machine, tensile testing machine, metallographic analyzer, nondestructive testing equipment, etc.

Cost-saving sourcing of raw materials and spare parts

We are in partnership with many top domestic manufactures of steels, valves, instruments and pipes. We directly buy raw materials from manufactures, not from any middlemen, thus reducing costs. All the raw materials have their manufacturer’s warranty. In addition, we conduct double checks on raw materials to ensure that they are qualified. By doing in this way, we guarantee both the best price and the finest workmanship.

Sound packaging and timely delivery

We take different packing approaches according to specific requirements. Wrapped bags and wooden boxes are commonly used for waterproof, dust-proof and shock-proof purposes, ensuring that every equipment remains in perfect condition after delivery.

In terms of logistics, the company has a large warehouse and a unique 800 ton private-owned wharf. We can deliver 500 tons of oversized cargos directly through the canal to Shanghai port. We also have several highways near us for land transport. We are 180 km from Shanghai port and 80 km from Hangzhou Xiaoshan International Airport. Customer visit and equipment delivery are both very convenient.
