OEM Service
About pairing,
All the pipes in our store are matched accurately (not all the pipes are matched) in the workshop of the factory.
We have the conditions and advantages to match multiple pipes according to customers' requirements (four, eight and twelve pipes with the same parameters).
The matching fee is included in most of the quotations of pipes in our shop, but very few pipes need additional matching fee.
