Buy & Import Double Bolt Clamps from Hebei Sinopulse Tech Group Co., Ltd. - Wholesale Supply

Double Bolt Clamps from Hebei Sinopulse Tech Group Co., Ltd. are engineered with dual gripping ridges on the inner surface and reinforced bolt lugs designed to resist misalignment under high-torque conditions. These clamps conform to DIN 20039 standards and are available in sizes ranging from SL22 to SL1275, suitable for hose diameters requiring precise clamping force. The product is manufactured in two variants: one with overlapping cast-on saddles and another with loose saddles and optional safety claws, both intended for secure, leak-free connections in demanding environments.

The clamps are produced in stainless steel 304 or carbon steel with zinc plating, offering corrosion resistance suitable for marine and industrial use. Surface treatments include yellow zinc, blue zinc, and white zinc finishes, applied via electroplating or sandblasting for durability. The material choice and coating thickness follow standard industry practices for medium to heavy-duty applications. Torque values are calibrated for dry bolts; lubrication is not recommended as it reduces holding force and risks clamp failure under vibration.

These clamps are commonly specified by manufacturers in automotive, HVAC, and marine systems where hose integrity under pressure is critical. Buyers typically order in bulk for OEM assembly lines or replacement parts distribution. Export-grade packaging is available, with each clamp individually wrapped and packed in cartons suitable for sea freight. Standard lead times are confirmed upon order, and Incoterms such as FOB Qingdao or CIF are negotiable based on shipment volume.

Frequently Asked Questions About Double Bolt Clamps from Hebei Sinopulse Tech Group Co., Ltd.
The inner diameter tolerance for DIN 20039 clamps is typically ±0.5 mm for sizes up to SL500 and ±0.8 mm for larger sizes. This ensures consistent hose seating and prevents leakage under pressure. Buyers should request a dimensional inspection report if precise fit is critical for high-vibration applications.

Sourcing Double Bolt Clamps from Hebei Sinopulse Tech Group Co., Ltd. - China Import Guide

Before ordering, verify the exact model number (SL22 - SL1275), material type (SS304 or carbon steel), and surface finish (yellow, blue, or white zinc). Confirm whether the clamp design includes safety claws or loose saddles, as these affect installation and durability. Request a sample if the application involves high vibration or chemical exposure. Do not rely on product images alone - dimensional drawings are essential for compatibility with existing hose systems.

Lead time is not specified in the listing and must be confirmed directly with the supplier. Standard export packaging is available, but Incoterms such as FOB, CIF, or EXW are negotiable. Payment terms typically require 30% advance and 70% against BL copy, though LC terms may be accepted for larger orders. Ensure the supplier provides a commercial invoice with HS code 7307.99 for customs clearance in most import markets.

Quality checks should include dimensional verification of inner diameter and saddle width, visual inspection for plating defects or cracks, and torque testing on at least 5% of the batch. Request a mill test report for stainless steel material and a salt spray test certificate if used in marine environments. Documentation must include packing list, certificate of origin, and safety data sheet if applicable. Reject shipments with visible rust, bent lugs, or mismatched model numbers.
