FRP Cross Fitting

Product Overview

FRP cross fitting is a pipeline component used for four-way connections, allowing four pipe runs to merge or divide. It is formed from fiberglass and resin and has good corrosion resistance. Used with FRP pipe it forms a complete anti-corrosion transfer system and avoids the problem of metal fittings rusting in a corrosive environment. The bore is smooth and flow resistance is low, the structure is strong, and the fitting withstands the pressure and loads of normal pipeline operation. The cross fitting is light and easy to install and adapts flexibly to complicated pipe layouts, which makes it an important connecting component in industrial piping systems.

The FRP cross fitting is well formed, with accurate dimensions at every outlet, so the pipe runs straight after connection and less adjustment is needed on site. The structure is continuous throughout with no weak points, and it keeps a reliable seal under pressure fluctuation and temperature change, so the pipeline stays safe in long-term service.

Technical Specifications

Cross fitting sizes cover DN50 to DN1000 and can be made as equal or reducing patterns to suit different diameter combinations for merging and dividing flow. Ends can be machined as sockets or flanges for flexible connection, and flanges can be made to a standard or to the customer's drawing. The resin system can be selected for the medium carried, meeting the requirements of acids, alkalis, salts and other corrosive media, and the pressure rating matches that of the pipe so that the whole system performs consistently.

Wall thickness is designed for the service pressure and the structural strength meets pipeline requirements; the connection length at each outlet is moderate, so little installation space is needed. Outlets can be combined in different diameters to suit complex layouts, dimensional accuracy is high, and the fitting seals reliably when matched to the pipe.

Production and Quality

After forming, every piece is checked for uniform wall thickness and a smooth bore, and the outside surface is ground flat and clean. Cross fittings for pressure service are pressure tested by batch to confirm that the joints seal reliably and do not leak. Dimensions and appearance are fully inspected before dispatch, the data is recorded and filed, and a quality inspection report is supplied with the product. Reducing crosses and special connection forms can be made to the customer's pipeline requirements, and installation guidance is provided so that the product is used correctly and performs reliably over the long term.

The company applies strict batch management, controlling the whole process from raw material inspection to finished goods so that quality stays consistent. Fitting and pipe mating dimensions are standardised for efficient site installation, large orders are supplied to the project programme, and pipeline construction gets dependable support.

Applications

FRP cross fittings are widely used in chemical pipe networks, municipal drainage, wastewater treatment and flue gas desulfurization projects, together with FRP pipe, elbows and tees, and suit pipeline systems that need multi-directional flow distribution especially well. Their corrosion resistance and long life noticeably reduce the frequency of pipeline maintenance and lower the whole-life cost. Hebei Zhengche Trading Co., Ltd. supplies a complete range of FRP pipe fittings, providing stable and dependable matching supply for pipeline projects.

In chemical and environmental protection projects, FRP cross fittings meet the demands of complex pipework carrying media in several directions and improve the flexibility of the system layout. With stable quality and thorough service, the company helps customers build efficient and durable transfer pipelines.
