Long radius 45 degree elbow (LR Elbow 45°) is a pipe fitting commonly used in industrial piping systems. Its main function is to achieve a smooth transition of direction while maintaining smooth flow of the pipeline. Compared with short radius elbows, the bending radius of long radius elbows is 1.5 times the nominal diameter (R=1.5D). This design can not only effectively reduce the impact force and pressure loss of the fluid at the bend, but also reduce pipeline wear and noise. Therefore, it has significant advantages in working conditions with high requirements for flow rate, pressure and system stability. In terms of application, 45-degree long radius elbows are widely used in oil and gas transmission pipelines, chemical plants, high-temperature and high-pressure boiler systems, power plant cooling water and steam pipelines, offshore platforms and ship equipment. It can not only improve the overall operating efficiency of the system, but also reduce maintenance costs.

Pipe fitting production process：

1.Cutting: cutting pipes according to size;

2.Forming: cold pressing/hot pushing bending, or die forging;

3.Welding (if split): grinding welds after welding;

4.Heat treatment: eliminating forming stress and improving mechanical properties;

5.Surface treatment: sandblasting, electroplating or coating with anti-corrosion layer;

6.Inspection: dimensional accuracy, pressure testing and non-destructive testing to ensure compliance with standards.

How do we ensure the quality of pipe fittings?
Raw Materials	Secondary inspection of raw materials Our raw materials come from large factories such as Baosteel, TSINGSHAN, Yongxin...Each batch of raw materials requires MTC and PMI. After the raw materials arrive, we conduct PMI and other inspections again to ensure that they meet the requirements.
During Production	Traceability of the production process Hongdi is equipped with CNC lathe, automatic laser cutting machine, 1,000tons hydraunlic press, elbow mandrel machine and other major productionequ equipment. Each process is supervised by experienced engineers and technicians. Each link is supervised by professional qc inspectors and photographed for archiving. The entire process uses process cards to ensure accuracy and traceability.
Before Shipment	100% inspection before shipment MTSCO has professional QC team to conduct a series of inspections and experiments on the fittings, including routine appearance, PMI, size, quantity, NDT and other inspections. At the same time, we also conducts mechanical testing, chemical composition analysis, intergranular corrosion and other laboratory tests. For welded pipe fittings we carry out 100% ultrasonic or radiographic testing of the raw material and pipe fittings. In addition, we also accept third-party inspection, such as SGS, TUV, and BV.
Packaging and Container Loading	As A factory complexes supplier, MTSCO has many years of experience in packaging and containerization. Conventional packaging methods are, large one wrapped in cling film, small one molded or wrapped in bubble wrap. The end is protected by pearl cotton. The outside is packed in wooden box/pallet, and the cabinet is reinforced with wooden strips and ropes. All inspection results and loading process will be documented with photos for your traceability requirements.
