Pruftechnik NDT, a German supplier of eddy current testing systems, provides equipment for inspecting semi-finished and finished products such as pipes, bars, and wire. The systems are suitable for detecting various defects—including longitudinal and transverse cracks, porosity, missed welds, and inclusions—in American Petroleum Institute (API) oil country tubular goods, seamless pipes, welded pipes, double-walled spiral-welded pipes, heat exchanger tubes, hot-rolled bars and wire, cold-drawn wire and bars, and billets. ● Comprehensive documentation of test results ● Fully digital signal processing with test frequencies ranging from 1 kHz to 1 MHz ● Operates in environments up to 40°C without the need for additional air conditioning ● High marking resolution helps reduce scrap

All pipe fittings manufactured by our company conform to Chinese national standards, American standards, European standards and other technical specifications. We also hold a variety of domestic and international qualification certificates, which allow our products to operate reliably in petroleum, natural gas, shipbuilding, chemical, power and military projects.

The FY800 is a fully automatic, consumable-free centrifugal oil purification device developed by Suzhou Fengyada. It uses high-speed centrifugal force (2800G) to separate impurities ≥5μm and moisture from oil, with a 3.2L drum capacity, 80L/min max flow, and 3.09kW power. Suitable for cold heading, drawing, hydraulic oils; operates stably at 0-80℃. Equipped with a PLC touch panel and variable speed control for adjustable centrifugal force. It features automatic slag discharge (no manual cleaning needed) and low oil content in sludge for direct disposal. Compact (870×860×1550mm), mobile installation, low noise, extends oil life by 3-5 times, and reduces O&M costs significantly.

FY600 Centrifugal Oil Purifier is a fully automatic, consumable-free oil purification device. It adopts high-speed centrifugal force (3500G) to separate impurities ≥3μm and moisture from oil, with a 4.5L drum capacity, 50L/min max flow, and 2.29kW power. Suitable for lubricating, hydraulic, drawing oils; operates stably at 0-80°C. Features automatic slag discharge, variable speed control, compact size (750×980×1480mm), low noise, extending oil & equipment life and reducing O&M costs。

Elbow is a pipe fitting that changes the direction of the pipe. According to the Angle, there are 45° and 90°180 "three most commonly used, and other abnormal Angle elbows such as 60 'are also included according to engineering needs. The methods of connecting with the pipe are: direct welding (the most commonly used way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection. The production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow and so on.

A flange is a part that is connected to each other between shafts and is used for the connection between pipe ends. There are also flanges used on the inlet and outlet of the equipment for the connection between two devices, such as reducer flanges. Flange connection or flange joint refers to the detachable connection of flanges, gaskets and bolts connected to each other as a set of combined sealing structures.

Reducer is a kind of pipe fitting (accessory) which is used in process piping to change the pipe size from a big bore to a smaller bore pipe. Mostly reducer use for a change in pipe size to meet flow requirements of the process system or connect to existing small or big piping bores as per requirements. The length dimension of the reducer is almost equal to the average of the big bore and smaller bore pipe diameters.
