Q1: What installation advantage does the "Rotating Flange" design offer refinery technicians?
In complex refinery layouts, rigid pipelines are often slightly misaligned, making fixed-flange installation incredibly time-consuming and dangerous, as forcing alignment twists the joint. The rotating (or floating) flange design allows the metal flange to spin 360 degrees completely independently of the rubber body. Technicians can match any bolt pattern instantly without placing any damaging pre-installation torque on the internal rubber or PTFE liner.
Q2: Can this PTFE-lined joint handle hot oil, fuels, and petrochemical solvents?
Yes, absolutely. Standard unlined elastomers like EPDM or natural rubber will rapidly soften, swell, and fail if they come into direct contact with petroleum products. The pure, high-molecular-weight PTFE lining creates an impenetrable barrier that keeps the oil and volatile hydrocarbons completely isolated from the outer structural rubber, ensuring long-term material stability.
Q3: Do I need to buy separate chemical-resistant gaskets to install this compensator?
No separate gaskets are needed. The internal PTFE liner extends completely through the throat of the joint and wraps over the face of the rubber collar. This flared PTFE face creates a built-in, full-coverage sanitary and chemical gasket. When compressed evenly against your pipeline’s mating flange, it forms an immediate, dependable, leak-proof seal.
