A pipe cap is a closed pipe fitting used at the end of a pipeline system. Its main function is to block the outlet of the pipeline to prevent leakage of the medium, while protecting the inside of the pipeline from external pollution and mechanical damage. It is usually welded or sleeved on the end of the pipeline. It can be used for permanent sealing or temporary sealing for system commissioning or maintenance. The pipe cap has a simple structure and good sealing performance. It is a common and important connection component in the pressure pipeline system. Pipe caps are widely used in industries such as petroleum and natural gas, chemical industry, electric power, food and pharmaceuticals, shipbuilding, water treatment, and municipal engineering. Its good sealing performance makes it irreplaceable in improving system safety, extending equipment life, and preventing medium leakage.

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.
