Product Features
- -Stainless steel lining.
- -Various anticorrosion materials can be chosen as the liner tube, such as stainless steel, copper, etc., depending on the corrosion properties to be encountered.
- -High heat-resistance, high pressure-resistance, and high corrosion-resistance all result in a long operation life — service life is 4 to 6 times greater than common tubing.
- -The mechanical performance is excellent, and meets the requirements of API standards.
- -The surface of the inside pipe wall is smooth, and has a lower friction factor which effectively increases the flow performance.
- -Competitive Pricing.
Delivery & Handling
- -Before loading pipe on flat deck, place blocking on trailer adjacent to strap tighteners to avoid bowing of pipe and easy access for off loading.
- -Check for loose or damaged protectors prior to loading.
Operation & Maintenance
- -Tubing drift/mandrel must conform to API specifications.
- -When running tubing, check to ensure coupling seal is intact.
- -Refer to torsion value chart below to avoid over torquing and damage to threads and seal.
- -Recheck seals when tripping and rerunning tubing.
- -Tubing to be pulled and racked should have protectors installed on both ends.
