FAQ
Q1: Besides the pipes themselves, can you provide related fittings and connection solutions?
A1: Absolutely. This is the core advantage of MTSCO’s one-stop procurement service. Since 2010, we have held a professional pipe fittings factory. We can provide butt-weld fittings, flanges, and other components that perfectly match 316L pipes, ensuring material integrity and consistent performance throughout your entire piping system.
Q2: What international certifications do your products hold?
A2: Our 316L seamless pipes are manufactured under ISO 9001 quality management systems. They also hold prestigious certifications including PED, M650, and AD2000. These ensure our materials fully comply with the stringent regulatory requirements for pressure equipment in the European and global markets.
Q3: How are the pipes protected and packaged for shipment?
A3: To prevent impact damage, both ends of the pipes are fitted with secure plastic caps. We then utilize reinforced woven bags or seaworthy wooden cases for packaging, ensuring the goods remain intact during long-distance maritime transit.
