I'm looking for one inch pipes available in either 16' or 20' lengths. The key requirement is that one end of each pipe must be designed to fit smoothly into the next pipe, facilitating a seamless connection. It's essential that these pipes are constructed to ensure durability and reliability for our intended applications. Please provide me with more details regarding your product specifications, including material options and any relevant certifications. I'd also appreciate pricing information, lead times, and minimum order quantities. If there are any additional features or customization options available, please highlight those too. Looking forward to your prompt response to discuss further!
